Designed specifically for the demands of the Biogas market, this analyser provides reliable and accurate measurement, helping you to optimise your productivity and improve plant availability. The MTL / Eaton GIR6000 innovative modular concept not only enables quick and easy installation and commissioning, but allows users to maintain sensors on-site without the need for engineer site visits or expensive service contracts. This integrated platform system also offers the flexibility of upgrading or expansion to meet future demands as your plant’s measurement needs evolve.
Biogas consists of a mixture of Methane (CH4) and Carbon Dioxide (CO2). Oxygen (O2) and Hydrogen Sulphide (H2S) are usually present in small quantities which have implications for gas quality, efficiency and safety. Dedicated modules for up to 4 gases are available for use in Zone 2 hazardous area applications. Other trace elements are also often present in low levels and may need measurement.
Methane is the desired component in fuel gas for CHP engines and gas-to-grid applications. We use long life NDIR sensors to measure Methane and Carbon Dioxide. These sensors are temperature compensated and designed to withstand the damp, corrosive nature of Biogas.
Hydrogen Sulphide is present in digester gas in varying amounts depending on the waste composition. Hydrogen Sulphide is highly toxic and can be extremely corrosive to engine generator sets. Accurate monitoring helps control scrubbing systems and prevent costly damage. Eaton has developed a system which allows for measurement of H2S, while still maximising sensor lifetime by automatically purging the analyser which rejuvenates the sensor.
Modular sensor design is an innovative feature of the MTL GIR6000. Self-diagnostics on each sensor provides important preventative data, minimising regular service and maintenance MTL GIR6000 Biogas Analyser Multiparameter analysers for biogas applications requirements. Replacement is quick and can be completed on-site, and the modules are pre-configured to allow for “plug-and-play” installation. All modules are replaceable in the field for minimum downtime.
Intuitive user interface features a large bright colour display. Simple to use menu’s allow the user to configure and interrogate the system locally. The display indicates live gas composition for CO2 and CH4 values and sensor status in addition to important error or alarm messages. The analyser automatically goes through a purge cycle every 45 minutes which rejuvenates both the H2S and the 02 sensors. A rugged and robust keypad allows configuration data entry. Password and hardware protection ensures that unauthorised changes cannot be made to the analyser configuration.
Sample conditioning is important in the variable conditions encountered in this application. MTL GIR6000 has integral sample filters and pump, as standard, which are fitted as field-replaceable modules. A low-flow alarm ensures sample flow integrity. An external coalescing filter option to further remove moisture can also be offered and we are equipped to recommend complete systems on receipt of full gas stream specifications.
These are hazardous area applications by their very nature. All MTL GIR6000 versions are designed for use in Zone 2 hazardous areas according to the Industry Code of Practice ESA ICoP Edition 2, a decision endorsed by the Health & Safety Executive in the UK.
