Abstract
A process for the stepwise separation of accompanying gases from a raw synthesis gas stream by a liquid absorbent countercurrently guided through all process steps and circulated via regeneration plants, wherein either the accompanying gases HS, COS and COare separated in a common absorption step or, in one of the selective absorption steps chiefly HS and COS are separated and in the next step in flow direction of the gas chiefly COis separated, and in the last step a separation of accompanying gas residues (fine wash) is effected, wherein before the separation of HS and COS an absorption step chiefly for the separation of aromatics and subsequently an absorption step chiefly for the separation of methyl mercaptan is carried out.
