Abstract
1356289 Desulphurizing Claus off-gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 15 July 1971 [17 July 1970] 33217/71 Heading C1A Off-gases containing sulphur dioxide from a Claus kiln are passed at a temperature above 175‹ C. together with a gas containing free hydrogen and/or free carbon monoxide over a sulphided Group VI and/or Group VIII metal catalyst supported on an inorganic oxide carrier, the reduced gases being then passed through a liquid and regeneratable absorbent for hydrogen sulphide and the unabsorbed portion, optionally after incineration, is discharged to the atmosphere, the hydrogen sulphide enriched absorbent being regenerated for re-use and the hydrogen sulphide rich gas mixture liberated being passed to a Claus process. Group VI metals specified are molybdenum, tungsten and chromium; Group VIII metals specified are iron, cobalt and nickel. The inorganic oxide carrier may be alumina, silica, magnesia, boron oxide, thoria, zirconia or a mixture of these compounds. The sulphiding may be carried out by use of the Claus off-gases themselves, the preferred temperature being between 300 and 400‹ C. The reducing gas preferably contains at least 20% by volume of free hydrogen or an equivalent amount of hydrogen/carbon monoxide mixture. Should any carbonyl sulphide be formed when carbon monoxide is used as the reducing gas it may be decomposed in known manner by passage over a heated bed of alumina. Amines and substituted amines in aqueous solution are the preferred absorbents, in particular alkali metal salts of dialkyl substituted amino acids (e.g. potassium dimethylamino-acetate) and polyalkanolamines such as di- or tri-ethanolamine and diisopropanolamine. After absorption, the H 2 S enriched absorbent is regenerated by heating and/or stripping, the H 2 S enriched gas mixture being recycled to the Claus plant and the regenerated absorbent re-used. Using high gas velocities at temperatures lower than 40‹ C. the selectivity of the H 2 S/CO 2 ratio is enhanced, CO 2 being usually present in the off-gases when the Claus process is operated using air. Other gases present which may be reduced to hydrogen sulphide by the present process include carbonyl sulphide and carbon disulphide.
