A world leader in catalyst science and technology
Johnson Matthey is a world leader in catalyst science and
technology. Every day, customers around the world rely on our
catalysts, our technical expertise and our operational knowledge
to operate their processes and give them a competitive edge.
Having the best catalysts and technologies is key to the success of any process but especially so in Gas to Liquids (GTL) where reliability and even small gains in efficiency and output have a major impact on plant performance and profitability.
Since our foundation in 1817 the Johnson Matthey name has been synonymous with quality and integrity and for almost a century Johnson Matthey has been a reliable and proven supplier of catalysts and technology for synthesis gas processes. We manufacture the widest range of sulphur removal products for natural gas purification; we offer an unrivalled range of reforming catalysts and for almost fifty years we have led the world in methanol technology culminating in the development of the KatalcoJM ApicoTM range of synthesis catalysts in 2009.
Manufacture of Fischer-Tropsch catalysts is a core Johnson Matthey capability which we have developed over the past ten years. In that time we have developed the formulation or manufacture of a large number of Fischer-Tropsch catalysts, many in partnership with customers. This, together with the advanced characterization techniques and manufacturing processes we employ gives Johnson Matthey an unrivalled capability in the understanding of Fischer-Tropsch catalysis.
Johnson Matthey Davy Technologies (JM Davy) develops and licenses process technologies to the synthesis gas and other industries. JM Davy has for many years been the leading licensee of the Johnson Matthey Low Pressure Methanol (LPM) process and also develops and licenses technology for GTL and other processes.
The emergence of Coal to Liquids (CTL) and Biomass to Liquids (BTL) technologies presents additional challenges. While non-catalytic gasification or pyrolysis processes replace reforming these processes produce a synthesis gas deficient in hydrogen. This must be accommodated by use of an appropriate iron based Fischer-Tropsch catalyst, by adjustment of the H2:CO ratio with a shift catalyst or by addition of hydrogen from a separate steam reforming unit. Johnson Matthey provides products for each of these options. Gasification and pyrolysis processes also produce synthesis gases laden with impurities which must be removed before further processing and Johnson Matthey can provide catalysts and absorbents for this important part of the process.

Feedstock purification
Johnson Matthey manufactures the widest range of
sulphur removal products on the market. These catalysts
and absorbents have been formulated to operate over
a wide range of temperatures and process conditions
and to be simple and reliable in operation. Our products
hydrodesulpurize organic sulphur compounds, hydrolyze
COS and absorb H2S. Our product range includes high
(350-400oC) and low (220-300oC) temperature
hydrodesulphurization, pre-sulphided catalysts where
required for ease of start up and a range of H2S
absorbents covering temperatures from sub-ambient
to over 400oC. According to your specific requirements
we can provide a tailored combination of catalysts
and absorbents combining maximum sulphur capacity
with minimum residual sulphur in the treated gas.
The Johnson Matthey range includes KATALCOJM products
for conventional process conditions and PURASPECJM
products for low temperature applications and special
duties. The PURASPECJM range also includes products for
the removal of less common impurities including mercury,
arsine, hydrogen chloride and organo-chloride compounds.
The removal of mercury has become increasingly
necessary in recent years as compounds of the metal have
been found to be present in many gas sources and its
removal for both environmental and process reasons can
be essential. Mercury is an environmental hazard if emitted
to atmosphere or into waste water and its corrosive effect
on cryogenic sections of plant, with potentially serious
consequences, are now well known. Johnson Matthey
makes a range of absorbents for removal of mercury alone
or in combination with sulphur which are simple to operate,
have extremely long lives and do not release mercury in
the event of process upsets or changing process conditions.
Natural gas purification
Almost all natural gas contains sulphur and many
gases contain other impurities such as mercury. These
impurities need to be removed to low levels in order
not to poison steam reforming and other catalysts and
it has long been established that the more complete
the removal the more efficient the plant operation
and the longer the catalyst lives that can be achieved.
Fischer-Tropsch synthesis takes the requirements for
purification to a new level; cobalt Fischer-Tropsch catalysts
are extremely sensitive to even part per billion (ppb)
levels of contaminants including sulphur compounds and
these must be removed, typically to levels below 5 ppb.
Gas production Syngas generation Fischer-Tropsch synthesis Hydroprocessing Hydrogen manufacture

CTL and BTL processes
Coal and Biomass to Liquids processes
present new challenges in purification. High
temperature gasification of solid feedstocks
produces synthesis gases containing COS,
ammonia, HCN, metal compounds and other
contaminants which may be contained in the
feedstock such as arsenic and phosphorus
while lower temperature pyrolysis processes
produce gases contaminated with a wide
variety of organic and other substances.
Cleaning these gases generally requires a
series of processing steps including liquid
scrubbing, chemical conversions and the
use of solid absorbents. Johnson Matthey’s
PURASPECJM products can provide final
treatment to ppb levels in these situations.
Liquid treating
Separation of natural gas liquids (NGL) is a common
feature of feedstock processing upstream of GTL
plants and in many cases provides an important
revenue stream where these can be exported
or sold locally. These streams can be combined
with propane and butane LPG products from the
Fischer-Tropsch synthesis section and the NGLs may
require purification before the streams are combined.
Johnson Matthey supplies a range of high
efficiency PURASPECJM absorbents which
have been specifically designed for removal of
sulphur and mercury compounds from these
streams at low temperatures and in the liquid
phase. Impurities can be readily removed to ppb
levels and the PURASPECJM products provide
a reliable solution, robust to changes in feed
stream composition and process conditions.

Reforming catalysts & technology
conventional steam reformers. The elimination of the
heavy hydrocarbons minimises carbon formation in the
downstream reformer, the presence of hydrogen ensures
maximum catalyst activity and the CRG pre-reformer
also deals with any fluctuations in the composition of
the feedstock gas supply. The CRG pre-reformer can
also be used to process olefinic hydrocarbons being
recycled from the tail gas of the Fischer-Tropsch system.
With a light feed gas the CRG pre-reforming process
is endothermic and it has become common practice to
reheat the pre-reformed gas before introducing it to the
downstream reformer. By this means lower grade heat can
be collected and introduced to the reforming system, so
improving efficiency; the absence of heavy hydrocarbons
and the presence of hydrogen in the pre-reformed gas
allows very high reheat temperatures to be used
without risk of coking in the high temperature
preheater or in the reformer itself.
Johnson Matthey has manufactured steam reforming
catalysts and operated reforming processes over many
decades and today produces catalysts for all types of
process. Many of these products have their origins in
our experience of plant operation while some have been
developed specifically to address problems arising from the
extension of reforming technology into GTL processes.
Our record in the development of steam reforming
technologies is well known. We developed the
fundamental engineering data for the design of the
reforming furnace, invented the naphtha steam reforming
process and continued to advance reforming technology
with the development of Gas Heated Reforming.
Pre-reforming
Pre-reforming has its origins in the developments
surrounding the manufacture of towns gas in the 1950s.
Originally developed and used by British Gas to produce
towns gas from petroleum sources rather than from
coal, the CRG process has been used in over 70 plants
around the world, processing a variety of feedstocks
from natural gas to naphthas. Johnson Matthey
Process Technologies manufactures the range of CRG
catalysts whilst the process is licensed by JM Davy.
The highly active CRG catalysts operate in adiabatic
reactors at low temperatures. The C2 and heavier
components of the feed are reformed to synthesis gas
and the process stream is equilibrated at the catalyst
temperature to produce a lean, hydrogen containing
gas free of C2 and higher hydrocarbons. As such it is
ideally suited to pre-process the feed to highly stressed
reforming units such as Autothermal Reformers
(ATR), Gas Heated reformers (GHR) and high heat flux

catalyst and high pressure drop in the lower parts of
the bed and further downstream where the evaporated
catalyst subsequently condenses back to solid material.
Also, as the top catalyst loses material and therefore
activity, the endothermic reforming reactions slow
down, catalyst temperatures increase and the problem
worsens and moves further down the catalyst bed.
Johnson Matthey’s scientists have studied these effects
in detail and have developed an ultra-stable catalyst and
support combination which is not susceptible to these
high temperature effects. Used with our regular ATR
catalysts in the lower parts of the bed this combination
is providing robust and reliable ATR service.
ATR technology incorporating Johnson Matthey’s
catalysts is supplied by JM Davy.
Combined reforming
Combined reforming combines a conventional steam
reformer with an autothermal reformer, the ATR being fed
with a mixture of reformed gas and desulphurised natural
gas. In recent years combined reforming has become an
increasingly popular choice for large methanol plants and
may be considered a more established technical choice
for GTL when compared with ATR or GHR alternatives.
Combined reforming incorporating Johnson Matthey’s
catalysts is supplied by JM Davy.
Autothermal reforming
Autothermal reforming (ATR) has become an important
synthesis gas generation process for GTL plants. Suitable
for light natural gas feedstocks, it can be configured
to produce a synthesis gas composition suitable for
cobalt Fischer-Tropsch catalysts and it can be scaled to
large capacity units. Autothermal reforming has been
used for many decades in the production of ammonia
(secondary reforming) and more recently in methanol
plants (combined reforming). The process has been
very successful but is technically challenging especially
in the combustion section of the reactor where both
equipment and catalyst experience a severe environment.
The severity of the conditions in an ATR for both the
burner and the catalyst cannot be overstated. The
Johnson Matthey burner unit is a proprietary design
first developed around 1970. Whereas burners in other
designs generally require frequent refurbishment or repair,
at intervals sometimes measured in months, the Johnson
Matthey units have operated for periods of over 20 years
with air and 14 years with oxygen without damage.
The catalyst in an ATR can be damaged by a poorly
designed, or damaged burner resulting in flame
impingement or local overheating of the catalyst in the
upper part of the catalyst bed. The reactor will only
perform well if the combusted gas is fully burnt and well
mixed as it enters the catalyst bed and the burner is
critical in this respect. However, conditions are so severe
in these reactors that even with a well designed system
and properly functioning burner the top catalyst can
experience problems. Specifically, at the high temperatures
involved, the nickel on alumina catalysts usually employed
are volatile and both the active nickel and the alumina
support evaporate. This results in wasting of the upper

Water gas shift catalysts
Hydrogen plant catalysts
Coal to Liquids (CTL) and Biomass to liquids (BTL)
plants produce, by gasification or pyrolysis, a synthesis
gas rich in carbon monoxide. The H2:CO ratio is lower
than that required for the stoichiometric conversion to
paraffinic hydrocarbons. CTL and BTL plants may elect
to use an iron based Fischer-Tropsch catalyst which
re-adjusts the equilibrium and effectively converts
part of the carbon monoxide to hydrogen, rejecting
carbon dioxide in the process. However, if a cobalt
Fischer-Tropsch catalyst is to be used the H2:CO
ratio must first be adjusted to approximately 2:1.
The H2:CO ratio can be adjusted by adding hydrogen
from a conventional steam reforming plant. However,
this requires a source of a suitable feedstock such
as natural gas which may not be available and,
in the case of a BTL plant, the addition of large
amounts of hydrogen produced from fossil fuels may
undermine the green credentials of the project.
The preferred way to adjust the stoichiometry
is to shift all or part of the synthesis gas using a
catalyst. Johnson Matthey makes a range of shift
catalysts and is the leading supplier of sulphided
or sour shift catalysts. This is the shift catalyst
of choice for CTL and BTL plants in which the
synthesis gases at this point are generally laden
with sulphur and other impurities. These catalysts
have been widely used in substitute natural gas
(SNG) and other coal based plants and have a long
track record of efficient and robust operation.
Hydrogen is an integral part of any GTL, CTL or BTL plant.
In plants based on partial oxidation of natural gas or on coal
or biomass feedstocks, large quantities of hydrogen may be
needed to blend with the CO rich synthesis gas from the
partial oxidation reactors or gasifiers. In almost all plants
hydrogen is also required for product finishing operations.
Johnson Matthey has extensive experience in hydrogen
manufacture and produces a comprehensive range of
KATALCOJM catalysts for use in the process. The range
includes catalysts for desulphurization and removal of other
impurities, pre-reforming, steam reforming and water gas
shift (high, medium and low temperature) catalysts. The
range is being constantly improved and updated as our
catalyst science develops and as customer requirements
change. Catalysts are also available for pre-shifting Fischer-
Tropsch tail gas where this is to be used as the feed to
the hydrogen manufacturing unit (HMU). In particular, our
range of reforming catalysts can successfully process the
heavy hydrocarbon components which may be present
in some natural gases and Fischer-Tropsch tail gases.
The latest KATALCOJM steam reforming catalysts
are produced in a QUADRALOBE™ shape,
specially designed to maximize activity and
heat transfer while limiting pressure
drop through the catalyst tube.
All these catalysts are fully
supported with technology
and services for both large
and small hydrogen units.

Synthesis gas purification
It is usual practice in gas based plants to complete the purification upstream of the first catalytic reactors – usually the reformers. However, for a variety of reasons this may not be possible; new impurities such as COS may be introduced by partial oxidation units or contaminated gases may be blended into the synthesis gas stream. And in coal or biomass based plants the synthesis gas is usually heavily laden with impurities which must be removed to very low levels before the Fischer-Tropsch section.
Synthesis gas is more reactive than natural gas. This limits the options for removal of impurities and the process conditions that may be safely used. With CTL and BTL plants purification usually begins with liquid scrubbing processes to remove bulk levels of contaminants and specific impurities such as ammonia and hydrogen cyanide. The gas is then finally purified to the required ppb level using solid catalysts and absorbents in fixed bed reactors. In GTL plants any required synthesis gas purification would be confined to the use of solid catalysts and absorbents.
Johnson Matthey’s extensive range of sulphur absorbents are particularly suitable for synthesis gas duties since the range includes products which are active at low temperatures and can achieve extremely low levels of impurity in the treated gas. With the very large gas volumes to be treated it is important to avoid high pressure drops and this can be difficult with conventional fixed bed reactors. Johnson Matthey offers proprietary designs of radial flow reactors which achieve very low pressure drop while providing complete purification of the gas and enabling easy changeout of the catalyst or absorbent at the end of its life.
One particular class of troublesome contaminant is metal carbonyls, usually nickel and sometimes iron, which can arise from the reaction between CO rich synthesis gas and pipework or items of plant equipment. Johnson Matthey can provide products to guard against these contaminants entering the synthesis section.

Fischer-Tropsch catalysts
Since their beginnings in the early decades of the twentieth century, Fischer-Tropsch catalysts based on both cobalt and iron have been used for producing hydrocarbon fuels from coal derived synthesis gas. The increases in oil prices in the 1970s spurred a further wave of development focused on natural gas feedstocks and this continued as large quantities of stranded gas became available. Fischer-Tropsch technology provides an effective way of converting large amounts of natural gas in remote locations into transportable liquid fuels. More recently, as the energy spectrum has changed, the technology is being further adapted to the production of fuels from biomass and, once again, from coal.
Since the turn of the century, the focus of Fischer-Tropsch developments has shifted towards the optimization of catalyst formulations and catalyst manufacture. New formulations have been developed to suit specific reactor technologies and an increased understanding of the linkages between catalyst manufacture and performance is enabling us to tailor manufacturing processes towards maximizing the performance of the catalyst in the plant. This understanding has been made possible by the development and use of advanced techniques for studying catalyst structure and Johnson Matthey’s scientists are at the forefront of these developments.
During the last ten years Johnson Matthey has worked closely with a number of leading companies, developing and optimizing the manufacture of Fischer-Tropsch catalysts on a commercial scale. With our extensive laboratory scale and pilot scale preparation facilities we can rapidly develop the manufacture of your catalyst formulation and can produce demonstration quantities for evaluation and testing. Our new, flexible, state of the art manufacturing facility can produce hundreds of tonnes of Fischer-Tropsch catalysts for large scale demonstration or for small to medium scale commercial plants. Catalysts can be supplied in oxide form or reduced, encapsulated and ready to go.
We work in close co-operation with our customers, using our skills and facilities to develop the efficient manufacturing processes necessary for cost effective manufacture of the highest performance catalysts. Our target is always to match or exceed the performance of your laboratory prepared samples and to contribute to still further improvements in the longer term.
Cobalt Fischer-Tropsch catalysts for slurry bubble reactors
Slurry bubble reactors can be an attractive technology choice for large commercial projects. Cost effective and with the potential to scale to very large capacities, these relatively novel reactors nevertheless place a considerable strain on the catalyst. To operate successfully, the Fischer-Tropsch catalyst must achieve high activity and selectivity with exceptional

robustness and stability to the gruelling physical and chemical regimes in these reactors. These properties are determined by both the formulation and the manufacturing processes for the catalysts.
Johnson Matthey will work with you to scale up the manufacture of your catalyst and to develop this further as your requirements change. We have developed an extensive collection of processes and characterization techniques that we apply to manufacture your catalyst and to predict its behaviour in your plant. Catalysts for slurry bubble processes are normally supplied pre-reduced and encapsulated in wax and we draw on our many years of experience in reduction and encapsulation to supply these products as clean, free-flowing pastilles which are easy to handle and load into the Fischer-Tropsch reactor.
As an alternative to your own formulation we can offer a proprietary Johnson Matthey catalyst which offers exceptional physical and chemical stability under Fischer-Tropsch conditions. Our patented manufacturing procedures underpin this unique and highly robust formulation.
Cobalt Fischer-Tropsch catalysts for fixed bed reactors
Fixed bed, tubular Fischer-Tropsch reactors can be the right choice for both smaller plants and for large multiple train facilities where the minimization of technical risk is attractive. These reactors present different challenges to the catalyst. In addition to the usual requirement for high activity and selectivity, fixed bed catalysts must possess excellent heat transfer and pressure drop characteristics, have high tolerance to thermal gradients and be strong and robust to simplify loading into the reactor and to ensure a long life.
Johnson Matthey has developed and adapted a range of technologies for the manufacture of fixed bed catalysts and our long experience in forming processes ensures that your formulation is produced with the characteristics required to ensure an efficient and trouble-free life.
Iron Fischer-Tropsch catalysts
While cobalt catalysts have become the preferred choice for natural gas based Fischer-Tropsch plants, the special characteristics of iron catalysts can be suited to coal or biomass feedstocks. The water gas shift reaction is promoted by iron and the catalyst compensates for the low hydrogen content of the synthesis gas by converting excess carbon monoxide to additional hydrogen and carbon dioxide. Iron catalysts typically produce very low levels of methane and, although thorough clean up of the synthesis gas is still necessary, the catalysts are less affected by low level residual traces of impurities.
Johnson Matthey has a long heritage in Fischer-Tropsch catalysts and these were first made in our factory at Oberhausen many years ago. Our proprietary iron catalyst has been optimised for fixed bed duties and is well suited to processes requiring this type of catalyst.
Special catalysts for special situations
While slurry bubble and fixed bed reactors will be used for the majority of Fischer-Tropsch plants, a number of other proprietary reactor designs have been developed to suit particular situations and special Fischer-Tropsch reactors may be matched with novel synthesis gas generation systems. While these use the same basic chemistry as more conventional plants the catalysts may be required in very different physical forms or may have to be specially adapted in other ways to suit a particular reactor technology.
Within the Johnson Matthey group we have expertise
in almost every aspect of catalyst manufacture
and our corporate research centres are continually
extending our understanding and capabilities. We
can work with you to develop and produce special
catalyst products to suit almost any situation based on
your knowledge and requirements and our catalysis,
characterization and manufacturing expertise.
We welcome long term cooperation on projects
but we are often able to adapt products from our
existing programmes on a shorter timescale.

Process technology
Fischer-Tropsch water treatment
JM Davy has an impressive track record
in the development of advanced process
technologies. Developed in collaboration
with BP, JM Davy’s GTL process combines
compact reforming and other reforming
technologies with fixed bed Fischer-Tropsch
technologies in a cost effective process.
In the case of compact reforming the units
are factory built and easily transported and
the fixed bed Fischer-Tropsch reactors,
also suitable for BTL and CTL plants, are
reliably scaled from existing units with years
of operational experience behind them.
A 300 barrel per day demonstration plant
began operation in Alaska in 2002 and has
provided a wealth of operational data at
effectively a commercial scale (since tubular
reactors are used), thus virtually eliminating
the scale up risk in the design of commercial
units. Development work also continues on
alternative reactor and process configurations.
The Fischer-Tropsch process generates
considerable quantities of co-produced water
which must be used within the plant or treated
efficiently for use elsewhere or disposal. The cost
of treatment, which may include secondary and
tertiary biotreatment and other capital intensive
processes is considerable in any GTL plant.
From our long experience in methanol technology
and licensing, Johnson Matthey provides natural
gas saturator technology which efficiently removes
oxygenates and other organic contaminants from the
co-produced water. The organics are stripped from
the water in the saturator by contact with hot natural
gas and returned to the reformers as feedstock
where their recovery contributes to the
overall efficiency of the plant. The
saturator generates the process
steam for the reformers using
low grade heat and surplus
water is cleaned of 99% of
its organic contaminants,
thus rendering it
suitable for other uses
or greatly reducing the
need for subsequent
effluent treatment.

Process and system modelling
Technical service and projects
Johnson Matthey has developed and maintains extensive expertise in the modelling of reactors and catalytic processes. We have particular strength in reforming and a detailed capability in the modelling of autothermal and other reformers by computational fluid dynamics (CFD) and other techniques. In addition to the catalytic systems themselves we model related parts of the plant such as flue gas ducts and other systems.
This expertise leads to the improved design and enhanced performance of our catalyst products and the systems in which they are used. We can also offer this expertise for the troubleshooting and improvement of our customers’ proprietary reactors and plant systems.
Customers often tell us that catalysts alone are not sufficient to ensure the best possible performance from a plant. As a business with an operating heritage in the industry and people on our team who have designed, built, operated, monitored and maintained plants over a period of more than 30 years, we know this to be true.
Through KATALCOJM PERFORMANCE we offer a wide range of services, from loading and start-up assistance through to detailed plant modeling and optimization advice. However, our abilities and expertise go far beyond this. By working in close co-operation with a number of partners, we can deliver a wide range of studies and services covering the key areas of concern to plant operators: Efficiency, Reliability, Throughput, Safety and the Environment. Examples of these include reformer surveys, revamp studies, measuring exact reformer tube temperatures and energy efficiency studies.
These services can be provided on a case by case basis or as part of a more comprehensive long term service agreement to accompany the use of Johnson Matthey.

We will develop purchasing strategies with you to ensure that the significant quantities of these metals required for your commercial GTL plants can be obtained at competitive prices.
Johnson Matthey provides a full range of catalyst reprocessing services which ensures that spent catalysts are transported and reprocessed in efficient and environmentally acceptable ways. The valuable metals are recovered and credited to customer accounts as quickly as possible while other components are generally put to use as secondary raw materials.
We provide this service for our full range of both precious metal and base metal catalysts. For precious metals the Johnson Matthey name is synonymous with the production, marketing, reprocessing and handling of the whole range of platinum group metals, rhenium, silver and gold.
Fischer-Tropsch catalysts present particular challenges for the reprocessor since the latest catalysts have complex formulations and quantities are large. Recovering all the valuable components can be difficult and Johnson Matthey is developing new recovery technologies to ensure that efficient recovery processes are available as the market for these catalysts develops. The recovery of spent catalysts will be an integral part of the supply of catalysts to large GTL plants and will provide plant operators with the assurance of best environmental compliance as well as maximum cost effectiveness.

Instrumentation and diagnostics
Fischer-Tropsch reactors
Slurry bubble reactors are an attractive technology
choice for Fischer-Tropsch synthesis. Combining
high productivity with economies of scale for large
plants, these reactors effectively solve the heat
management problems associated with
fixed bed reactors and provide the uniform
reaction conditions necessary for efficient
operation with either cobalt or iron catalysts.
Fischer-Tropsch synthesis is the first large-scale
application of this type of reactor and units are
being built and operated on a scale not before
seen. The reactor environment is complex with
liquid product, catalyst particles and reactant
gases all interacting in a complex set of physical
and chemical processes. These must be well
understood and closely controlled to achieve
maximum productivity and efficiency.
The performance of slurry bubble reactors
depends on a number of critical parameters
including catalyst distribution and attrition rates,
gas distribution, bubble characteristics and back
mixing, and heat transfer parameters. These
parameters are generally difficult to measure
or to infer from other data and yet are crucial
to the successful operation of these units.
Modern GTL plants incorporate many
large and complex systems that must
work reliably and efficiently together for a
successful project. Accurate measurement
plays a key part in monitoring, controlling
and understanding these systems.
As part of Johnson Matthey Process Technologies,
Tracerco offers GTL operators a wide range of
established and developing measurement and
diagnostics techniques which are ideally suited
to improving the monitoring, troubleshooting
and understanding of these complex systems.
Tracerco’s bespoke solutions can be applied to
gas production, Fischer-Tropsch reactors and
many other process systems within GTL plants.

Tracerco with over 50 years’ experience in
advanced process plant monitoring and diagnostics
analysis, offers a collection of intrusive and
non-intrusive measurement techniques enabling
real time characterization of conditions in the
industrial process for both routine monitoring
and troubleshooting on this type of reactor. A key
element of Tracerco’s technology is the ability to
diagnose a wide range of production problems using
sophisticated tracer and advanced measurement
technology. Techniques are normally carried out
online by highly trained and experienced Tracerco
engineers, require minimal site preparation and
provide immediate, onsite results for the customer.
These methods can verify conventional
instruments, give highly reliable non-intrusive
measurements for process control in hostile
environments, and provide unique measurements
not possible by other techniques. Taken together,
the measurements made possible by Tracerco’s
process diagnostics and specialist measurement
teams provide an unparalleled capability for
monitoring, process control, troubleshooting and
design development of slurry bubble reactors.
