Carbon dioxide from biogas

In a biogas plant, carbon dioxide and water vapour are produced in parallel to methane. If the methane is separated by amine scrubbing, moist CO2 remains, which can only be processed for material utilisation in a dry state.
The project investigates novel membranes for energy-efficient drying of carbon dioxide streams. The developed process is based on the principle of capillary condensation.
