Abstract
A process of treating aqueous condensate which is formed as a result of the cooling of raw gas produced by the gasification of solid fuels under a pressure of 5 to 150 bars. The condensate formed as a result of the cooling is at a temperature of at least 110.degree. C. and under a pressure of at least 2 bars and at least part of it is pressure-relieved. The flashed-off vapor is removed and the pressure-relieved condensate is fed to a separator, from which a condensate phase consisting mainly of water is withdrawn. The condensate or a portion thereof is used as a coolant for the raw gas. The flashed-off vapor may be burnt.
