Abstract (en)
[origin: EP0776961A1] This new process cleans gases from the partially-oxidative gasification of carbonaceous materials at 700-1100 degrees C. Solids entrained in the gases are separated by a cyclone. In the new process, a gas extraction line leaves high on the cyclone; solids leave via a low outlet channel. Through this channel in addition, a side stream, 5-30% of the gas, is led with the solids into an oxidation chamber. Here, at 1300-1800 degrees C, a lean oxygen supply produces either flue- or fuel gas, and slag. This gas, together with gas from the extraction line of the cyclone, is led into a mixing chamber. The mixture has a temperature of 900-1200 degrees C, and residence time at least of 0.5 seconds. Gases extracted from the mixing chamber are cooled.
