Biogas Upgrading Plants

PSA Biogas Upgrading and Purification Plants | Mahler AGS

PSA Biogas Upgrading and Purification units are designed for the biomethane generation from biogas.

The pressure swing adsorption (PSA) technology employs the basic principle of gas separation at ambient temperatures by using carbon molecular sieve (CMS; a material that adsorbs carbon dioxide to leave a rich stream of biomethane).

Mahler AGS biogas upgrading plants are based on pressure swing adsorption technology for capacities from about 500 to 5000 Nm³/h.

01. High yield for methane and product purity

02. No operating personel required

03. Automatic adaption to the quality of raw gas

04. Support via remote monitor
