Method and device for obtaining gas products
The invention relates to a method and to a device for physical gas scrubbing, wherein a feed gas (1) containing hydrogen, carbon monoxide, carbon dioxide and also carbonyl sulphide and/or hydrogen sulphide is conducted through a first scrubbing section (w1) in countercurrent to a scrubbing medium preloaded with carbon dioxide, in order to separate sulphur components substantially selectively off from the feed gas and to generate a desulphurized gas mixture (3). In a second scrubbing section, carbon dioxide is separated off from only a subquantity of the desulphurized gas mixture by scrubbing with an unloaded scrubbing medium (4) and the resultant carbon dioxide-preloaded scrubbing medium is used completely in the first scrubbing section (w1) as scrubbing medium..
