Biogas Digesters By Bryce Dinger
Copying Nature to Produce Energy
Barriers to BiogasInadequate payback/economics
Operations and maintenance complications and concerns
Digester heating costsLack of education
What is Biogas? Biogas is created when bacteria degrade
biological material in an anaerobic state, or the absence of oxygen
Biogas is a clean fuel produced from anaerobic digestion
Biogas is comprised of 55-65% methane, 35-45% carbon dioxide, 0.5-1.0% hydrogen sulfide and other traces of water vapor
Biogas is corrosive in nature making it difficult to store
Why Biogas?By harnessing biogas, various
types of energy can be produced Power has become a major
concern in rural regions of third world countries
Sanitation problems exist in every population, and digesters offer a healthy solution
Biogas Production4 stages within process1.Liquefaction2.Acid production3.Acetate Production4.Methane Production
A more practical example
