55Fundamentals – biogas CHP plant

1. Digester: Production of Biogas

2. Gas cooling system FriCon: Removal of

humidity coming along with the biogas

3. Reheating: Adjusting the relative humidity

4. Activated Carbon Filter ActiCo:

Removal of H2S

5. Blower: Delivery of biogas to the engine

6. CHP-unit with exhaust heat exchanger

77Fundamentals – gas drying for what?

• Fulfil the gas quality requirements of the enginemanufactures

• Optimizes the combustion process in the engine

• Avoiding condensation in the following gas pipes

• Partial separation of H2S

• Separation of solid particles

• Improvement of the caloric value (less water content)

• Gas is optimally conditioned for further cleaning steps (e.g.

activated carbon)
