Abstract
The present invention relates to a method and apparatus for converting carbon monooxide and/or carbon dioxide and hydrogen in a gas to methane and water. The gas comprising carbon monooxide and/or carbon dioxide is preferably a biogas, fluegas or syngas. The gas comprising hydrogen is preferably a gas obtained from electrolysis of water. The method and apparatus comprises an efficient cleaning of the packaging material without removing the packaging material from the reactor. Hereby, the efficiency of the conversion is maintained and optimised. In particular, the present invention relates to increasing the amount of green energy obtained from anaerobic digestion of an organic material by reducing the content of carbon dioxide and increase the content of methane in a gas.

Abstract
A process and apparatus for removing hydrogen sulphide from a gas is disclosed. The process comprises the steps of: providing a gas comprising hydrogen sulphide; supplying oxygen for the process if the gas does not comprise oxygen, or does not comprise sufficient oxygen for converting hydrogen sulphide to elementary sulphur; leading the mixture of gas and, if supplied, oxygen to a tank comprising i) a foam forming liquid, such as a scrubber liquid and ii) a foam layer made from said foam forming liquid on the top of the foam forming liquid where the hydrogen sulphide in the gas is oxidized to elementary sulphur to form a cleaned gas removed from hydrogen sulphide.
