Abstract

1517140 Purifying producer gas METALLGESELLSCHAFT AG 2 May 1977 [26 May 1976] 18355/77 Heading C5E A solids-laden crude gas at 350-800‹C, which has been produced by gasifying a solid fuel (e.g. coal) under a pressure of 5-150 bars with steam and/or free O 2 , is purified by removing some of the solids in a coarse purification stage (e.g. one or more cyclones) and then scrubbing the gas with a liquid hydrocarbon at 200-300‹C and having a maximum water content of 5 weight per cent, to give a gas having a high calorific value and low dust content. The gas leaving the coarse purification at above 350‹C may be cooled before scrubbing by being sprayed with water. Preferably at least 70% of the hydrocarbon scrubbing liquid has a b.pt. above 350‹C. The scrubbing may be carried out in one or more Venturi-type or radial flow scrubbers. The used scrubbing liquid may be separated into a heavy phase and a lighter phase, the former being recycled to the gasification reactor, and the latter to the scrubber.
