Abstract
Process for treating raw gas produced by the gasification of coal under elevated pressures and temperatures by a treatment with oxygen and steam and, if desired, additional gasifying agents such as carbon dioxide. The raw gas leaving the gas producer is cooled in a first condensing stage to a temperature which is in the range of 150.degree.-220.degree. C and 3.degree.-25.degree. C below the dew point temperature of the raw gas. The resulting condensate is withdrawn and the raw gas is conducted through at least one additional condensing stage. The condensate of the first condensing stage is treated independently of the condensate from the further stage or stages.
