Abstract
909,108. Making sulphur. POWER-GAS CORPORATION Ltd. June 27, 1960 [June 26, 1959], No. 21930/59. Drawings to Specification. Class 90 A process for the substantially complete removal of hydrogen sulphide from an industrial gas with recovery of sulphur comprises scrubbing the gas in an absorber zone with an absorbent liquor and removing hydrogen sulphide, deriving a gas rich in hydrogen sulphide from regeneration of the absorbent liquor, passing gas comprising the remaining hydrogen sulphide through at least one bed of particles of iron oxide and/or manganese oxide to remove the remaining hydrogen sulphide in the form of iron sulphide and/or manganese sulphide, mixing the derived gas rich in hydrogen sulphide with free oxygen and with sulphur dioxide, passing the resulting gaseous mixture through at least one catalyst bed to effect formation of elemental sulphur by the reaction of hydrogen sulphide and sulphur dioxide, and recovering the elemental sulphur, in which process 70-85% of the hydrogen sulphide is derived from heating the iron sulphide and/or manganese sulphide under oxidizing conditions. Preferably the partially purified gas leaving the absorber zone is passed through at least one bed of particles of iron oxide or manganese oxide or both to remove substantially all the remaining hydrogen sulphide therefrom. Alternatively the partially purified gas leaving the absorber zone may be scrubbed with an absorbent liquor in a second absorber zone to remove substantially all the remaining hydrogen sulphide therefrom, the spent abosrbent liquor leaving the second absorber zone being regenerated with evolution of gas containing hydrogen sulphide and the evolved gas being passed through at least one bed of particles of iron oxide or manganese oxide or both to effect substantially complete removal of hydrogen sulphide therefrom. The absorbent liquor may be partially selective for hydrogen sulphide, e.g. a liquor having a higher H 2 S- absorption rate than a CO 2 -absorption rate. Specified absorbent liquors are aqueous triethanolamine, aqueous N-methyl diethanolamine, aqueous potassium salt of N-diethyl or N- dimethyl aminoacetic acid, aqueous sodium phenolate and aqueous tripotassium phosphate. A regeneration system comprising a steam stripping zone may be provided for spent absorbent liquor. Partially purified gas leaving the first absorber zone may have its carbon monoxide content catalytically converted to carbon dioxide. Iron oxide and manganese oxide absorbers may be regenerated by burning when their activity declines. The absorbent oxides may be employed as fixed or fluidized beds. Examples are given. Specification 719,056 is referred to.
