Biogas storage, boosting & drying

Produced biogas from an anaerobic process can be stored, the need for biogas storage is usually of a temporary nature, at times when production exceeds consumption.

The most common storage systems are low-pressure systems; these systems are used for on-site, intermediate storage of biogas.

There are a number of benefits in drying biogas to a low dew point before combustion in a combined heat and power (CHP) engine or boiler.

The benefits of cooling (drying) to a low dewpoint are:

• Increased engine/boiler efficiency
• Prevention of corrosion/oil contamination
• Partial removal of impurities such as H2S, ammonia and siloxanes
• Complies with technical instruction of all major gas engine/boiler suppliers
It is therefore essential to use a cooling/drying system which has been specifically designed to produce low dew points and operate in aggressive ambient conditions such as those experienced in biogas applications.
