A special area in the field of plant construction is the upgrading of biogas to bio-methane. As one of the leading plant designers and constructors, VORWERK offers the most innovative and economical processes for the production of bio natural gas: amine gas treatment for the chemical absorption of acid gases and membrane technology. This is achieved by means of membrane-based gas permeation. Membrane technology is used to separate the carbon dioxide contained in the biogas from the methane. After this treatment and subsequent upgrading, the bio-methane is natural gas quality and can be fed into the natural gas network without restrictions.

Looking ahead, retrofitting biogas plants with VORWERK gas treatment systems offers attractive economical and environmental benefits.
