Reliable and accurate measurement data is crucial to help control and optimise the production process. requirements. Replacement is quick and done on-site, without special tools or training and the modules are pre-configured to allow “plug-and-play” installation. All modules are replaceable in the field for minimum downtime. Biogas consists of a mixture of Methane (CH4) and Carbon Dioxide (CO2). Oxygen (O2) and Hydrogen Sulphide (H2S) are usually present which have implications for gas quality, efficiency and safety. Dedicated modules for up to 6 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. 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 values and sensor status in addition to important error or alarm messages. A rugged and robust keypad allows configuration data entry. Password and hardware protection ensures that unauthorised changes cannot be made to the analyser configuration. Methane is the desired component in fuel gas for CHP engines and gas-to-grid applications. MTL 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. MTL has developed a system which allows for continuous measurement of H2S, while still maximising sensor lifetime. 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 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. The enclosure contains a heater to avoid condensation forming in the analyser. An external coalescing filter option to further remove moisture can also be offered. MTL are ready to recommend complete systems on receipt of full gas stream specifications. These are hazardous area applications by their very nature. All 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.
