Abstract
The invention relates to a method for operating a gas scrubber, in which a feed gas () containing hydrogen, carbon monoxide, carbon dioxide and carbonyl sulfide and/or hydrogen sulfide is scrubbed in a scrubbing apparatus (A) using a scrubbing agent () preladen with carbon dioxide in order largely selectively to separate the sulfur components from the feed gas and to produce a desulfurized gas stream (). The invention is distinguished in that a sulfur-free scrubbing agent () is used which, on introduction thereof into the scrubbing apparatus (A), has a carbon dioxide partial pressure which is greater than or equal to the carbon dioxide partial pressure in the feed gas () to be desulfurized.
