Abstract
1402274 Purification of sulphur ENTERPRISE DE RECHERCHES ET D'ACTIVITES PETROLIERS (ELF) 20 Oct 1972 [9 Nov 1971] 48472/72 Heading C1A [Also in Division B1] Liquid sulphur from the Claus reaction containing hydrogen sulphide is cooled and contacted at 125-100‹ C. with a gaseous fraction from he Claus reaction, injecting into the resulting liquid a basic compound which is volatile at the operating temperature of the subsequent stripping with an inert gas, and stripping the residual hydrogen sulphide by means of an inert gas at a temperature between 125‹ and 140‹ C., thus degassing the liquid sulphur. The basic compound may be ammonia or a light volatile amine. The inert gas may be nitrogen, air, carbon dioxide gas or the rare gases.
