General:

Biogas, sewage gas and landfill gas always contain water vapour in an unsaturated state. During combustion, the water vapor results in considerable corrosion damages to the gas engines. Malfunctions caused by these damages lead to significant downtimes and high repair costs. Removing the moisture from your biogas, using a biogas dehumidifier, will protect your CHP engine and other equipment from corrosion and minimize long term maintenance costs.

A standard biogas dehumidifier consists of a gas to cold water heat exchanger integrated with an industrial grade water chiller. The condensation of the water vapour in the gas is caused by temperature reduction which in turn results in a dehumidification. The condensate is separated out in a trap installed after the chiller and removed via a siphon and auto drin system.

The use of a gas dehumidification system can considerably extend the engine’s service life and notably reduce the maintenance costs.

Benefits:

Removing the moisture from your biogas, using a biogas dehumidifier, will protect your CHP engine and other equipment from corrosion and minimize long term maintenance costs. Oil, which is an essential lubricant in the CHP engine, is less likely to become contaminated and require changing. Your engine will spend less time offline and will perform better, for longer, by simply adding a gas dehumidifier to your system.
The biogas dehumidifier only takes up a small space and can be incorporated into an existing system or designed into a new plant. It will shut down and start up at the touch of a button to ensure engine downtime is kept to a minimum.
