DID YOU KNOW?

Siloxanes are used frequently in industrial processes and many consumer products, therefore sometimes they can be introduced into feedstocks and then volatilise into the biogas being produced.  These silicon-containing gases can cause damage to gas engines and other AD plant equipment because when they are heated they form hard, glass like shards which damage surfaces and other engine parts.  There are various methods for removing siloxanes including activated carbon beds and siloxane removal systems.

We also have a fantastic diagram which visually takes you through the biogas monitoring process. Take a look!

Palm oil processing in Malaysia

Application Biogas from palm oil Customer EnviroEquip Requirement A biogas monitoring system was required to monitor the raw biogas being produced, and to then monitor the biogas after it has been processed in a desulphurisation unit. The site uses 2 x GA3000s for this purpose. Operation The site was originally set up as a CDM... Read more »

Other applications

Farm waste AD (small scale)

Individual farms install AD (anaerobic digestion) plant and use for on-site heating to generate revenue and dispose of farm waste, which may be a mixture of animal and plant waste.

Mixed food waste AD

Local authorities and waste contractors install AD plants to dispose of mixed organic waste and generate revenue.

Sewage / waste water treatment AD

AD of human waste has been common in many countries for years but increasing energy costs now drive efficiency. Sewage processors are large energy users and AD can offset and help manage this.

AD Research

Many universities, government departments and specialist operators carry out research. This can be using full-scale pilot AD plants or small-scale laboratory experiments.
