Westech Industrial Ltd. is a leading supplier of analytical instrumentation and process control equipment to a wide variety of industries. Our products include: flame and gas detection, process analyzers, valves and measurement control solutions. Westech also manufactures flame arresters and provides industrial valve servicing.
Biogas is produced by controlled degradation organic materials which can be contained in a sealed digester tank. Biogas is comprised of a complex mix of different gases, which usually includes methane (CH4) and carbon dioxide (CO2). In most plants the methane gas is either recovered as fuel or flared off as waste. In order to optimise plant productivity it’s important to ensure reliable and accurate measurement of these gases.
Westech Industrial only works with the best gas analyzers in the market and has a team of experts that can work with you to build customized Sample Conditioning Systems as well as custom structured packaging of our analyzers to meet the needs of the renewable energy industry.
Gas Analyzer Brands:
BARTEC – Available Canada Wide
Biogas from digesters is normally collected from headspace above a liquid surface or very moist substrate, the gas is usually saturated with water stream. The amount of saturated water vapour in a gas depends on temperature and pressure. Biogas typically contains 10% water vapour by volume at 43°C, 5% by volume at 32°C, and 1% by volume at 4.5°C. The removal of water vapour (moisture) from biogas reduces corrosion that results when the H2S and CO2 have not been removed from the biogas because the H2S and CO2 and water vapour react to form different acids, which can result in a severe risk factor in equipment that comes into contact with the biogas.
Bartec HYGROPHIL®-K 4326-31 is a combination of a high-quality capacitive humidity-sensor and the newest microprocessor technology. These are the guarantee for best accuracy, excellent long-term stability, small hysteresis and high resistance to pollutants. The HYGROPHIL®-K 4326-31 offers easy installation and on-site adjustment. These features guarantee a simple service and a high availability in any applications.
ENOTEC – Available Canada Wide
Energy conservation not only makes a valuable contribution to protecting the environment but is also a cost factor. Particularly energy intensive processes in biogas and biomass boilers can be optimized through a comprehensive and continuous process analysis. With the help of combustion optimization, one is able to control the combustion process optimally and therefore the energy consumption can be permanently reduced.
In order for combustion processes to run efficiently, the combustion process needs to be optimized appropriately. ENOTEC can provide you with this market leading flue gas and process analysis technology. Enotec analyzers are suitable for gas analysis in small to medium sized combustion boiler, measurement in large combustion chambers, or for continuous measurements in high temperature installations.

Optical Hydrocarbon Analyzers
Gasera – Available Canada Wide
Greenhouse gas (GHG) emissions especially methane (CH4) and nitrous oxide (N2O) play a significant role in the global warming and climate change. Methane (CH4) has 25 times and nitrous oxide (N2O) 296 times higher GHG effects than that of carbon dioxide (CO2), which leads to the secondary atmospheric contamination. The global warming and climate change are continuing to be a threat to our planet.
Gasera’s new portable product, GASERA ONE GHG greenhouse gas analyzer offers a selective, reliable and simultaneous analysis of methane (CH4) and nitrous oxide (N2O) greenhouse gas emissions with highly accurate low-ppb detection limits. It offers an affordable and easy-to-use tool for continuously monitoring the background levels of methane (CH4) and nitrous oxide (N2O). GASERA ONE greenhouse gas concentration analyzer can achieve below 10 ppb detection limit for CH4 and 2 ppb detection limit for N2O.
HOBRÉ Analyzer Solutions – Available Canada Wide
The production of biogas from organic waste material has become important as a sustainable source of energy. Raw digester biogas typically has a high H2S and water content that must be removed before injection into the gas grid. Plus, various technologies like membrane separation, CO2 scrubbing, pressure swing absorption and cryogenic are used to upgrade the gas.
For monitoring compliance with Rule 21 at the injection point of upgraded biogas into the gas grid the Gatekeeper analyzer system offers a cost-effective, high accuracy and low maintenance solution. The system includes a TDL-PA analyzer for measuring H2S, H2O and CO2 and a continuous WIM Compas analyzer for measuring CH4, H2, O2 and calculating N2. Besides these components, also Specific Gravity, Wobbe Index and Heating Value (BTU) are available as outputs. For on-line monitoring of siloxanes Hobré can offer separate a separate FTIR analyzer delivering specialized and total siloxanes.
