Abstract
1434029 Gas purification WOODALLDUCKHAM Ltd 6 Dec 1973 [22 Dec 1972] 59404/72 Heading C5E The circulating reagent in a gas purification process in which the H 2 S in a foul gas stream is absorbed by a liquid reagent and thereby converted to sulphur which is recovered from the reagent, the latter being regenerated and recycled for absorption of further H 2 S, is decontaminated by bleeding-off a sidestream of contaminated reagent and subjecting the same to high-temperature hydrolysis in a non-oxidizing atmosphere, thereby to produce a gas phase containing H 2 S, and recycling the gas phase to the foul gas stream being subjected to purification by the process. The hydrolysis may be a spray-roaster or equivalent device in which the sidestream is distributed as droplets in a non- oxidizing atmosphere comprising the products of combustion of a fuel/air mixture. The hydrolysis may take place at 50‹ to 800‹ C. within a period of 5 to 15 seconds. A solids residue produced by the hydrolysis step may be subjected to high-temperature reduction, e.g. by coke oven gas at 500‹ to 800‹ C.
