Biogas and landfill gas always contain water vapor in an unsaturated state. During combustion, the water vapor results in considerable corrosion damage to the gas engines and flares.

The condensation of the water vapor 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. The de-humidification simultaneously results in increased efficiency.
