Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

CASE STUDY

Biogas Research Success withAutomatic Monitoring

Automated biogas analysis has helped in a successful research project to determine methane gas yield from potatoes in an anaerobic digester Data appear instantly on screen as collected and indicate the percentage of CH4 CO2 and H2S in the biogas someasuring its quality These measurements can be used to calculate the biogas methane yield per tonne oforganicdrymatterAtGreenfinchresearcherBeckyArnoldsaidldquoDatareadingseverythirtyminutesfromthe static biogas analyser enhanced our depth of knowledge and understanding of digester behaviour and response It transformed data acquisitionrdquoGreenfinch used Geotechrsquos Automatic Extraction Monitoring System (AEMS) exclusively in a potatotrial in a pilot-scale digester at its research facility in Ludlow BeforeusingtheautomaticmonitoringoftheGeotechAEMS system set at 30-minute intervals Greenfinchanalysed biogas output volume and quality manually once a day before adding the potato feed to the digester Nowwith 48 automated reading everydayfor three months of the trial Greenfinch biogas researchers were able to observe changes in the digesterrsquos response 24 hours per day and specifically look at its response following feeding BeckyArnold said ldquoOnce commissioned byGeotechtheirequipmentranfaultlesslyItgaveusallthedatawe needed on screenwith Internet browsers in ouroffices or from anywhere we needed it at any time of day or night When we had queries support from Geotechwasexcellentrdquo

Looking at role of automatic biogas gas analysis and monitoring Greenfinch confirmed one likely beneficialusefortheAEMSiswithCHPengineswhereveryaccurateandregularmonitoringofH2Sisneededin order to protect the engines This also brings the

benefit of constantly available data on the percentage of methane within the biogas Given the significant investment in biogas plants and the ever-increasing value of the biogas continuous monitoring may have much to offer to the bio-energy industry

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Biogas Research Success withAutomatic Monitoring

Automated biogas analysis has helped in a successful research project to determine methane gas yield from potatoes in an anaerobic digester Data appear instantly on screen as collected and indicate the percentage of CH4 CO2 and H2S in the biogas someasuring its quality These measurements can be used to calculate the biogas methane yield per tonne oforganicdrymatterAtGreenfinchresearcherBeckyArnoldsaidldquoDatareadingseverythirtyminutesfromthe static biogas analyser enhanced our depth of knowledge and understanding of digester behaviour and response It transformed data acquisitionrdquoGreenfinch used Geotechrsquos Automatic Extraction Monitoring System (AEMS) exclusively in a potatotrial in a pilot-scale digester at its research facility in Ludlow BeforeusingtheautomaticmonitoringoftheGeotechAEMS system set at 30-minute intervals Greenfinchanalysed biogas output volume and quality manually once a day before adding the potato feed to the digester Nowwith 48 automated reading everydayfor three months of the trial Greenfinch biogas researchers were able to observe changes in the digesterrsquos response 24 hours per day and specifically look at its response following feeding BeckyArnold said ldquoOnce commissioned byGeotechtheirequipmentranfaultlesslyItgaveusallthedatawe needed on screenwith Internet browsers in ouroffices or from anywhere we needed it at any time of day or night When we had queries support from Geotechwasexcellentrdquo

Looking at role of automatic biogas gas analysis and monitoring Greenfinch confirmed one likely beneficialusefortheAEMSiswithCHPengineswhereveryaccurateandregularmonitoringofH2Sisneededin order to protect the engines This also brings the

benefit of constantly available data on the percentage of methane within the biogas Given the significant investment in biogas plants and the ever-increasing value of the biogas continuous monitoring may have much to offer to the bio-energy industry

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Biogas Research Success withAutomatic Monitoring

Automated biogas analysis has helped in a successful research project to determine methane gas yield from potatoes in an anaerobic digester Data appear instantly on screen as collected and indicate the percentage of CH4 CO2 and H2S in the biogas someasuring its quality These measurements can be used to calculate the biogas methane yield per tonne oforganicdrymatterAtGreenfinchresearcherBeckyArnoldsaidldquoDatareadingseverythirtyminutesfromthe static biogas analyser enhanced our depth of knowledge and understanding of digester behaviour and response It transformed data acquisitionrdquoGreenfinch used Geotechrsquos Automatic Extraction Monitoring System (AEMS) exclusively in a potatotrial in a pilot-scale digester at its research facility in Ludlow BeforeusingtheautomaticmonitoringoftheGeotechAEMS system set at 30-minute intervals Greenfinchanalysed biogas output volume and quality manually once a day before adding the potato feed to the digester Nowwith 48 automated reading everydayfor three months of the trial Greenfinch biogas researchers were able to observe changes in the digesterrsquos response 24 hours per day and specifically look at its response following feeding BeckyArnold said ldquoOnce commissioned byGeotechtheirequipmentranfaultlesslyItgaveusallthedatawe needed on screenwith Internet browsers in ouroffices or from anywhere we needed it at any time of day or night When we had queries support from Geotechwasexcellentrdquo

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

CASE STUDY

Biogas Research Success withAutomatic Monitoring

Automated biogas analysis has helped in a successful research project to determine methane gas yield from potatoes in an anaerobic digester Data appear instantly on screen as collected and indicate the percentage of CH4 CO2 and H2S in the biogas someasuring its quality These measurements can be used to calculate the biogas methane yield per tonne oforganicdrymatterAtGreenfinchresearcherBeckyArnoldsaidldquoDatareadingseverythirtyminutesfromthe static biogas analyser enhanced our depth of knowledge and understanding of digester behaviour and response It transformed data acquisitionrdquoGreenfinch used Geotechrsquos Automatic Extraction Monitoring System (AEMS) exclusively in a potatotrial in a pilot-scale digester at its research facility in Ludlow BeforeusingtheautomaticmonitoringoftheGeotechAEMS system set at 30-minute intervals Greenfinchanalysed biogas output volume and quality manually once a day before adding the potato feed to the digester Nowwith 48 automated reading everydayfor three months of the trial Greenfinch biogas researchers were able to observe changes in the digesterrsquos response 24 hours per day and specifically look at its response following feeding BeckyArnold said ldquoOnce commissioned byGeotechtheirequipmentranfaultlesslyItgaveusallthedatawe needed on screenwith Internet browsers in ouroffices or from anywhere we needed it at any time of day or night When we had queries support from Geotechwasexcellentrdquo

Looking at role of automatic biogas gas analysis and monitoring Greenfinch confirmed one likely beneficialusefortheAEMSiswithCHPengineswhereveryaccurateandregularmonitoringofH2Sisneededin order to protect the engines This also brings the

benefit of constantly available data on the percentage of methane within the biogas Given the significant investment in biogas plants and the ever-increasing value of the biogas continuous monitoring may have much to offer to the bio-energy industry

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

CASE STUDY

Biogas Research Success withAutomatic Monitoring

Automated biogas analysis has helped in a successful research project to determine methane gas yield from potatoes in an anaerobic digester Data appear instantly on screen as collected and indicate the percentage of CH4 CO2 and H2S in the biogas someasuring its quality These measurements can be used to calculate the biogas methane yield per tonne oforganicdrymatterAtGreenfinchresearcherBeckyArnoldsaidldquoDatareadingseverythirtyminutesfromthe static biogas analyser enhanced our depth of knowledge and understanding of digester behaviour and response It transformed data acquisitionrdquoGreenfinch used Geotechrsquos Automatic Extraction Monitoring System (AEMS) exclusively in a potatotrial in a pilot-scale digester at its research facility in Ludlow BeforeusingtheautomaticmonitoringoftheGeotechAEMS system set at 30-minute intervals Greenfinchanalysed biogas output volume and quality manually once a day before adding the potato feed to the digester Nowwith 48 automated reading everydayfor three months of the trial Greenfinch biogas researchers were able to observe changes in the digesterrsquos response 24 hours per day and specifically look at its response following feeding BeckyArnold said ldquoOnce commissioned byGeotechtheirequipmentranfaultlesslyItgaveusallthedatawe needed on screenwith Internet browsers in ouroffices or from anywhere we needed it at any time of day or night When we had queries support from Geotechwasexcellentrdquo

Looking at role of automatic biogas gas analysis and monitoring Greenfinch confirmed one likely beneficialusefortheAEMSiswithCHPengineswhereveryaccurateandregularmonitoringofH2Sisneededin order to protect the engines This also brings the

benefit of constantly available data on the percentage of methane within the biogas Given the significant investment in biogas plants and the ever-increasing value of the biogas continuous monitoring may have much to offer to the bio-energy industry

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

Biogas Research Success withAutomatic Monitoring

Automated biogas analysis has helped in a successful research project to determine methane gas yield from potatoes in an anaerobic digester Data appear instantly on screen as collected and indicate the percentage of CH4 CO2 and H2S in the biogas someasuring its quality These measurements can be used to calculate the biogas methane yield per tonne oforganicdrymatterAtGreenfinchresearcherBeckyArnoldsaidldquoDatareadingseverythirtyminutesfromthe static biogas analyser enhanced our depth of knowledge and understanding of digester behaviour and response It transformed data acquisitionrdquoGreenfinch used Geotechrsquos Automatic Extraction Monitoring System (AEMS) exclusively in a potatotrial in a pilot-scale digester at its research facility in Ludlow BeforeusingtheautomaticmonitoringoftheGeotechAEMS system set at 30-minute intervals Greenfinchanalysed biogas output volume and quality manually once a day before adding the potato feed to the digester Nowwith 48 automated reading everydayfor three months of the trial Greenfinch biogas researchers were able to observe changes in the digesterrsquos response 24 hours per day and specifically look at its response following feeding BeckyArnold said ldquoOnce commissioned byGeotechtheirequipmentranfaultlesslyItgaveusallthedatawe needed on screenwith Internet browsers in ouroffices or from anywhere we needed it at any time of day or night When we had queries support from Geotechwasexcellentrdquo

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

While landfill gas analysis has been required for compliance biogas analysis has different drivers It can help optimise digester operation andmaximizemethane production Biogas analysis assistsprocesscontrolwhichinturncanhelpprotectCHPorotherenginesfromH2SandmoisturedamageItcanalsoensurenewlyinstalledbiogasplantisoperatingtodesignspecification

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

ANAEROBIC DIGESTER GAS

BIOGAS OVERVIEWMethanemakesmoney It generates energy revenues carbon credits and is part of bio-treatmentsludgeprocessingMeasuringwhatwearedoingandbeingresponsiblewiththispotentiallydamaginggreenhouse gas makes good environmental and commercial sense

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

When methane is in production analysis is achieved either with hand held portable instruments or static unmanned and automated equipment The need for data may dictate the equipment specified For carbon credit trading automatic data logging secure data transfer and automatic calibrationare likely to be the norm The same equipment can also monitor digester performance and alert operators if intervention is required To run power-producing plant on methane possibly from an array of sources less frequent measurement may be needed and hand held portable equipment may be totally adequate That means finding the project dependant balance between man hour cost of using portable equipment and the capital outlay of automated equipment

Money talks

Whilst landfills and digesters both generate methane in similar biological processes there are differences in how the recovery process is monitored and operated There is no doubt that advanced technology and automation can improve system monitoring Since the gas quality and quantity determine the project payoff tight control on system operation is crucial to a projects commercial success Optimising a process for maximum gas production whilst maintaining compliance withenvironmental protection regulations is a delicate balance requiring constant attention With combined pressure of environmental consciousness and commercial return the need to make the right choice from available technology is greater than ever A comprehensive system should include components that address sampling the gas analysing the composition of the gas collecting and validatingdataand reporting the informationconsistentlyandaccuratelyQuite simplyusing theright technology can allow more to be delivered in less time Working closely with an experienced technology partner greatly increases the likelihood of success

There`s Money In MethaneMethane gas measurement has developed rapidly andtechnology is migrating to other business sectors globally The driver for this demand is the global business of energy fromwasteMeasuringmethane has a big future Fromthefirstminersrsquosafetylampsoftheearly1800stoinfraredcell measurement today methane is taken seriously When mixed with air this gas is dangerously explosive in confined spacesIntheatmosphereasagreenhousegasitissometwenty times more heat retentive than carbon dioxide The need to manage methane to avoid its problems and now to reap its rewards as an energy source spans many countries and activities They include landfill management waste-to-energy carbon credit trading bio-fuel production and coal mining right back where it started for capture as an energy resource The expertise that enabled accurate gas analysis is continuously developing With global feedback from landfill operators and EfW producers ranging from the UK to Korea Japan Germany USA and South America development never stops Whether in a portable gas analyser or in an unmanned fixed gas analysis cabinet withremoteInternetaccessattheheartareinfraredandelectrochemical cells Detectors measure the amount of infrared light that passes through the gas being analysed The cell requires little or no routine maintenance and has a lifetime of many years To ensure safe operation with an explosivegasmixtureandachieveATEXCertificationonetechnique is to wire-mesh shield the infrared light source using an idea first seen in the minersrsquo safety Davy lamp introducedin1815

For oxygen carbon monoxide and hydrogen sulphideelectrochemical cells are used to measure the gases They are simple to use but have a limited lifetime typically two years and must be replaced Carbon monoxide is usually a trace gas but accurate measurement is important as an increase in its concentration can indicate landfill site fire The quest for green or renewable energy is stimulated by many factors finite future supplies of oil and other fossil fuels growth in energy demand and rising oil and gas prices Others include the need to manage landfillgas and developments in processing waste to generate energywithagrowingoutputvalueandviaCDMtradein carbon credits These developing trends show no sign of diminishing and every sign of strengthening With them they bring new economics and knowhow to the world of gas analysis This is at a time when fast-moving technology offers much and promises more to aid the task ofgasanalysisPortablegasanalysershavetheadvantageof spreading a relatively small capital investment over an enormous number of landfill boreholes and require nothing on site Technicians take portable analysers to site obtain readings at agreed intervals record and transfer data in line with agreed protocols Much is now doneviaPCdownloadEvenmoresimplyformanyGermanorBrazilianfarmerssellingbio-electricityarelativelysimpleportable biogas analyser has been sufficient especially when used in a farming cooperative on several sites Gas
