Meeting the ever-changing demands of the global biogas market
Fixed biogas analysers from Geotech are now available with additional options for moisture management to help with challenges from wet biogas.
A new variant on the reliable GA3000 PLUS also provides oxygen (O2) measurement designed for very low O2 levels, and new pre-calibrated cells for all models will reduce onsite service downtime even further.
Geotech fixed analysers were first launched in 2011 with the GA3000, an easy to install and simple to use gas analyser for methane (CH4), carbon dioxide (CO2), O2, and hydrogen sulphide (H2S). This single sample point system for continuous monitoring evolved in 2012 to become the GA3000 PLUS, and included options for up to three sample points as well as high and low H2S for pre and post desulphurisation monitoring. The GA3000 PLUS can also optionally monitor carbon monoxide (CO) and hydrogen (H2) as additional gases and is available with Modbus and Profibus communications.
There are now over 300 Geotech fixed systems installed in a variety of applications across the globe, from waste water treatment in the UK, to palm oil processing in Malaysia, and CHP engine protection the world over.
Now, for 2014, Geotech are introducing the latest improvements to the GA3000 PLUS to cater for the varying needs of a wide range of anaerobic digestion (AD) and biogas applications.
The flexibility of the GA3000 PLUS has been enhanced with new options for additional moisture management. Biogas is generally very humid and condensate can form within the system, leading to failures and damage if not managed correctly. Gas chilling systems can be expensive and fragile, so Geotech has developed a simple, robust system suitable for all biogas monitoring applications. This is an add-on option to the GA3000 PLUS which is already designed to offer market-leading resistance to problems from wet biogas. One feature is the automated drain feature on the catch pot.
This removes the need for an engineer to visit site to maintain this part of the system, saving time and resource on site. The range of user-replaceable parts has also been extended to include pre-calibrated electrochemical cells, allowing them to simply be replaced with no need for user calibration.
In addition to these new features, the popular continuous monitoring variant of the GA3000 PLUS, the GA3KPLUSC, has been superseded by the new GA3KPLUSE. The GA3KPLUSE builds on the strong reputation of accuracy and reliability of all the GA3000 PLUS models with an improved O2 measurement to give a longer life on the O2 cell in O2 deficient applications. It uses an automated daily 3 minute air purge to keep the O2 cell healthier for longer, reducing operating costs.
Geotech closely supports its fixed biogas systems around the world and is continually developing the platform to meet the changes of the biogas market.
