Abstract

1277606 Treating gases with liquids FUJI IRON & STEEL CO Ltd 20 Nov 1969 [20 Nov 1968 (2) 6 Feb 1969 20 Feb 1969 (2)] 56872/69 Heading B1R [Also in Divisions C5 and C7] An apparatus for washing and cooling a gas from a gasifier comprises a chamber 61 into which a gas inlet pipe 8 depends, a cylinder 63 surmounted by a water-vapour separating plate 68 surrounding the end 62 of the pipe 8. Water is delivered at 66 and a controller LTC regulates the water level in the chamber 61 by actuating a valve 65 on a water outlet pipe 64. Cooled gas leaves at 67.
