Landfill gas analysis telematics in Slovenia on-line in UK

A landfill gas to energy site in Slovenia needed a 6-channel biogas analyser. Installed and commissioned in June by Automatic Flare Systems (AFS), Coventry with a twin-booster, 600 cu m/ hr flare stack, the Geotech AEMS static gas analyser measures five input lines and one output line to flare that will eventually go to two 400kw CHP engines, due for installation later. At the CeROD landfill in an ex-quartzite quarry in Novo Mesto, Slovenia, AFS client, Minerva Žalec d.d specified a 6-channel gas analyser.

For AFS, Geotech in Leamington Spa responded with a customised AEMS gas analyser built to order. The gas analysis and flare stack data have secure on-line Internet access. From the AFS flare and Geotech AEMS, data crosses to site offices by a remote link and from there on to a SCADA system. The data is then linked via broadband for secure Internet viewing. In addition the Geotech AEMS static biogas analyser has a direct GPRS link. These telematic links enable the Geotech AEMS gas analyser and the AFS flare stack systems to have on-line data download and diagnostics from anywhere and is part of Geotech service and support. Flare stack data includes flare temperature, suction on each inlet line, pressure on the gas-engine line and flow rate while the gas analyser is set to sample each of six lines sequentially at three minute intervals. On each gas line, the Geotech AEMS unit checks methane, oxygen, carbon dioxide and hydrogen sulphide.

The Geotech Automated Extraction Monitoring System (AEMS) static gas analyser has extensive application options with multiple sampling points, data inputs and 4-20mA local data outputs, Profibus and Modbus comms options, Ethernet and Internet connectivity, data logging and data transfer. For applications not requiring the extensive capability of Geotech AEMS, the user-installed Geotech GA3000 static gas analyser delivers exactly what many users need and at a very attractive package price.
