Abstract

In a process for cooling hot process gases from a pressure gasification reactor the hot process gas is passed through a heat exchange with water to produce saturated steam and then in countercurrent heat exchange with said saturated steam to generate superheated steam, production of saturated steam and superheated steam are performed in a single pressure vessel. Correspondingly the two necessary heating surfaces packages are arranged in an upright pressure vessel one above the other.
