„Gas permeation is a process for the separation of gas mixtures. In a permeation a substance (permeate) passes through a solid. The gas that is to be separated is fed with pressure into a gas separation module. In this the substances migrate due to the pressure difference through a selective membrane. Thus, the raw gas stream is separated into a retentate and a permeate.”

EnviCare® Engineering GmbH is currently working on a research project on membrane distillation so that the available application knowledge over the gas permeation is significantly expanded.
Gas permeation competes against conventional methods
The process of gas permeation is nowadays commonly used to separate biomethane from biogas and competes with washing processes, which uses the solvents amin, pressure water or glycol, but also with adsorption and must be assessed in each individual case.
