Anaerobic Digester Gas Monitoring
February 2010
Anaerobic digesters are now commonplace at water utility companies as the waste-to-energy possibilities of sewage become apparent. Thus water companies are increasingly interested in gas analysis. Methane is the fuel gas and needs to be measured to optimise generator set efficiency. Depending on the source of the substrate, hydrogen sulphide can be present in variable quantities and high levels can destroy expensive generators.
The GIR5000 biogas analyser from Hitech Instruments is a 2 or 3 gas analyser measuring methane and hydrogen sulphide with an option of oxygen or carbon dioxide. Hitech design and manufacture according to customers applications and other sensors will be available on demand.
Hitech Instruments were the first company to introduce a purpose designed, fixed biogas analyser that is Zone 2 ATEX compliant – a requirement in this application.
The GIR5000 uses Hitech’s proven sensor technology and robust electronics making it highly reliable in field use. There are no consumables and the maintenance requirement is very low. Occasional checks will determine if calibration is necessary.
Hitech realise that the analysis is only as good as the sample presented to the sensors. A coalescing filter to remove water and an internal pump in case of variable flow are recommended options. Contact Hitech today with your specific application requirements for a detailed quotation.
