摘要： Systems and methods are described for selectively removing an acid gas from a feed stream to reduce co-absorption of CO2. The system can include an absorber configured to contact at least a portion of the feed stream with a caustic solution or other basic solvents to produce a clean stream substantially depleted of the acid gas. To reduce co-absorption of CO2 by the caustic solution to less than 10% of the CO2 present in the feed stream, the absorber can be further configured to receive a driver gas that is substantially non-reactive with the caustic solution.

摘要： The present invention accordingly relates to a method for regenerating spent aqueous absorption liquid used in the selective removal of sulphur and/or sulphur containing contaminant compounds from a gas flow. The spent aqueous absorption liquid is regenerated by converting the solid metal salt into solid sulphur and/or a solid sulphur containing compound and converting the corresponding metal salt into the metal ion in solution with aid of a polyvalent second metal (which is the strongest oxidiser). The regeneration process may consist of four process steps: regeneration, oxidation, extraction and crystallisation.

摘要： The problem of chemical consumption and undesirable formation of sulfur-containing salts inherent in conventional processes, such as the Stretford and Takahax processes, for the removal of hydrogen sulfide from gas streams are substantially reduced by the use of a novel, substantially quinone-free washing solution containing solubilized vanadium, thiocyanate ions, a carboxylate complexing agent and one or more water-soluble nonquinone aromatic compounds capable of solubilizing vanadium. Hydrogen sulfide is removed from the hydrogen sulfide-containing gas stream (12) by contact with the washing solution (14). The absorbed hydrogen sulfide is converted to elemental sulfur by reaction with the washing solution. The sulfur is separated (36) and recovered. The washing solution is oxidatively regenerated (24) before being recycled (30) to the absorber (10).
