Biogas is a popular source of renewable energy. However, production and conversion of biogas at the same location can result in energy losses up to 60 %. This energy loss can be reduced by upgrading the biogas to biomethane for injection into an existing gas delivery network and other uses. In order to upgrade the raw biogas produced from agriculture and industrial plants unwanted and harmful gases like CO2 and H2S need to be removed. An innovative process for biogas conditioning using hollow fiber membrane contactors is presented. In comparison to membrane gas separation no elevated pressure is needed. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The invention relates to a system for treating natural gas that contains methane, comprising: a) at least one degassing module (1) and/or at least one percolator, and b) at least one gas exchanging module (2). The invention is characterized in that the degassing module (1) and/or the percolator and the gas exchanging module (2) are connected in a water circuit and arranged successively in the flow direction of the water. The water is degassed in the degassing module (1) and/or percolator, and the degassed water absorbs undesired gases from fed natural gas in the gas exchanging module (2). The fed natural gas is fed to the at least one gas exchanging module (2) in countercurrent to the degassed water. The invention further relates to a method for treating natural gas that contains methane, said method being carried out in the system according to the invention.
