METHOD FOR SELECTIVE DESULPHURISATION OF A SYNTHETIC RAW GAS

The invention relates to a method for operating a gas scrubber, in which a feed gas (1) containing hydrogen, carbon monoxide, carbon dioxide and carbonyl sulfide and/or hydrogen sulfide is scrubbed in a scrubbing apparatus (A1) using a scrubbing agent (3, 4) preladen with carbon dioxide in order lar...

Beschreibung
Zusammenfassung:	The invention relates to a method for operating a gas scrubber, in which a feed gas (1) containing hydrogen, carbon monoxide, carbon dioxide and carbonyl sulfide and/or hydrogen sulfide is scrubbed in a scrubbing apparatus (A1) using a scrubbing agent (3, 4) preladen with carbon dioxide in order largely selectively to separate the sulfur components from the feed gas and to produce a desulfurized gas stream (5, 9). The invention is distinguished in that a sulfur-free scrubbing agent (3, 4) is used which, on introduction thereof into the scrubbing apparatus (A1), has a carbon dioxide partial pressure which is greater than or equal to the carbon dioxide partial pressure in the feed gas (1) to be desulfurized.
