Continuous Biogas Analysis – More for Less

A new static gas analyser for anaerobic digestion (AD) biogas, and landfill gas monitoring suits tight-budget demand with top-quality design, components and engineering. The new GA3000 uses Geotech’s robust, field-proven technology to bring low-cost to automated fixed-position monitoring of methane-rich biogas. Easily operator installed, user field-calibrated and zeroed, the compact, self-contained, single-cabinet GA3000 has gas conditioning as standard. It continuously analyses CH4, CO2, O2 and optionally, H2S at 0-5000ppm. They are measured, at user-set timings, and supply data via three or four, 4-20mA local outputs. Users also set alarm levels and can see screen-displayed readings on a large, clear, backlit display.

Already creating a stir since its July 2010 preview at the UK Anaerobic Digestion and Biogas Association (ADBA) NEC show, the strong interest in the GA3000 is its application for AD, wastewater sludge treatment and landfill gas extraction. The GA3000 is available from Sept 2010.

AD is increasingly being used in waste processing and biogas production to recycle food and farm waste, avoid landfill and generate biogas and energy from waste. These AD installations, large and small, need continuous gas analysis to optimise AD, maximise output and ensure safety and compliance with environmental guidelines and legislation.

This new robust, reliable and cost-effective system provides continuous and accurate sampling of methane, carbon dioxide and oxygen from a single sample point. Hydrogen sulphide sampling is a GA3000 option. User field calibration of the analyser and exchange of the optional hydrogen sulphide (H2S) sensor reduce operational costs. 

With no training required and engineered for low ownership cost, this ISO 17025 calibration accredited unit is designed for quick and easy self-installation in any country, worldwide. User relocation of the GA3000 is just as easy. With gas conditioning included as standard, to ensure top quality gas analysis, the user-replaceable H2S sensor and analyser ‘Hot Swap’ capability offers zero downtime.

The GA3000 adds to Geotech’s static gas analysis range which includes the current Automated Extraction Monitoring System (AEMS) that has more extensive application options with, for example, multiple sampling points, data inputs and 4-20mA local data outputs, Profibus and Modbus comms. options, Ethernet and Internet connectivity, data logging and transfer. For applications not requiring the extensive capability of Geotech AEMS, the GA3000 now delivers exactly what many users need at the very attractive package price they want - available on application. The GA3000 will be on display, with more information, at EBEC 6-7 Oct., stand J17, Stoneleigh Park, Warwickshire UK. More: www.geotech.co.uk
