Abstract A process of treating an aqueous liquor which has been used to scrub a hot raw gas produced by the gasification of a solid, liquid or gaseous fuel, which liquor has dissolved therein gaseous pollutant, comprising flashing said liquor from a temperature of at least 100 DEG C and a pressure of at least about 5 bars in at least on preliminary flashing stage to an intermediate pressure in the range of about 1.1 to 4 bars, separating the flashed-off gases containing the bulk of the pollutants from the residual aqueous liquor, and then flashing off the residual liquor to atmospheric pressure. The pollutant gas may contain H2S and the gas product of the preliminary flashing can be fed to a Claus process for removing sulfur compounds.
