Static Gas Analysis Demand from Landfill, Water Treatment, Biogas and CDM/Carbon Credits

Many methane producers want frequent and accurate measurements. That requires automated, static analysers which operate round-the-clock, remotely, wirelessly and unmanned. These producers may be working with landfill gases or coal bed methane or anaerobic digesters making biogas from water-treatment sludge or food waste. They may be running CDM for carbon credits.

To meet this growing demand, Geotech’s has launched and installed automated fixed position, static gas analyser for CH4, H2S, O2, CO, CO2 and other gases. Called, Automatic Extraction Monitoring System (AEMS) it is based on Geotech’s 18-year history with its tried and tested portable gas analysers. The static AEMS installations use the same gas analysis technology. In timed, automated cycles they monitor and analyse gases, store data, auto-purge and calibrate themselves. The data arrives at a producer’s Internet screen enabling, for example, claims for carbon credits, digester management and CHP engine protection through H2S monitoring.

At UK biogas research specialist, Greenfinch, researcher Becky Arnold said, “Data readings every thirty minutes from the static biogas analyser enhanced our depth of knowledge and understanding of digester behaviour and response. It transformed data acquisition.” Greenfinch used Geotech’s AEMS equipment in a potato trial in a pilot-scale digester at its research facility in Ludlow. “Once commissioned by Geotech their equipment ran faultlessly. When we had queries, support from Geotech was excellent,” she said

At United Utilities using the Geotech AEMS equipment on sludge digesters, Colin Greenhalgh, wastewater treatment specialist, said, “We placed our order with Geotech. It arrived on time it was exactly what we expected and paid for which is excellent and Geotech are passionate about what they do. We are very pleased.“
