Abstract

See full text

The invention relates to a gas scrubbing process for purifying crude synthesis gas with methanol as a physical absorption medium, wherein an acid gas comprising at least hydrogen sulfide (H2S) is produced. The acid gas is produced in a hot regenerator arranged downstream of an absorption apparatus and subsequently separated from gaseous methanol in an acid gas separator by cooling and condensation. The acid gas separator has a condensation region and an absorption region, wherein both regions are separated from one another by a gas-permeable tray. This has the result that impurities such as hydrogen cyanide and/or ammonia outgassing from a first acid gas substream are not reabsorbed in the condensation region of the acid gas separator, thus avoiding an accumulation of impurities in the hot regenerator or other parts of the gas scrubbing plant. The invention further relates to an acid gas separator and to the use of the acid gas separator according to the invention in a process according to the invention.
