Abstract: In a process for the regeneration of a scrubbing medium which has been utilized in a scrubbing operation and therein loaded with scrubbed-out components, the scrubbing medium is expanded and regenerated and hence can be reused in the scrubbing operation. In order to be able to subject expansion gases obtained during the expansion to an after-treatment under elevated pressure, or to be able to discharge these expansion gases under a higher pressure, the loaded scrubbing medium is expanded in at least two stages. Expansion in one stage is performed by means of a liquid-jet compressor and the expansion gases of a subsequent expansion stage are brought to an elevated pressure by means of the liquid-jet compressor.

Abstract: A process for the simultaneous removal of H.sub.2 S, SO.sub.2 and elemental sulfur from gaseous mixtures, comprises treating the gaseous mixture with a solvent. After the solvent becomes loaded with the components to be removed, it is regenerated and reused. In order to obtain savings in costs and energy, the sulfur is separated from the loaded solvent by lowering the temperature thereof. In this way, chemical regeneration of the scrubbing medium takes place within the cycle eliminating the requirement for outside regenerating apparatus.

Abstract: In the removal of sour gases, H.sub.2 S in particular, from CO-containing gaseous mixtures containing heavy metal carbonyls by scrubbing under pressure at temperatures of below 0.degree. C. with a scrubbing medium, the scrubbing medium is regenerated by inter alia, being heated by means of heat exchangers, and such exchangers are normally fouled by precipitates of metal sulfides which owe their presence to the decomposition of the metal carbonyls to form reactive heavy metal which combines with sulfide ion. To avoid fouling of the heat exchangers, the CO partial pressure is increased during the heating of the loaded scrubbing medium, to above the partial pressure of the CO in equilibrium with the carbonyls in the scrubbing medium thereby preventing the decomposition of the carbonyls.
