Biogas to biomethane upgrader, 2500 Nm³/h

Biogas to biomethane upgrade is a complete solution suitable for biogas flow of 2500 m³/h. It uses self-regenerating vacuum pressure swing adsorption technology (VPSA) to clean biogas from CO₂.

VPSA is a physical process for separating gas mixtures resulting in a pure biomethane gas, that can directly substitute natural gas in any application, including vehicle fuel. Besides biomethane, biogas upgrade with an extra option allows to recover and liquefy CO₂ of the food grade, that can be used for food & drinks as well as for greenhouses. The upgrade system operates fully automatically and has remote control and monitoring. The biogas upgrade has a standardized modular design and is installed in containers, which are fully tested before being sent to the client. 

VPSA differes from PSA in the pressure 3 bar. Thus it requires less electric energy. Instead of 0,22 kWh per m3 biogas it's required just 0,15 kWh per m3.
