Abstract: A method for the recovery of a methane-rich natural gas from a natural gas containing, apart from methane, also hydrogen sulfide, carbondioxide, higher hydrocarbons and, in most cases, organosulfur compounds. According to the invention a hydrocarbon fraction of C.sub.4 hydrocarbons and higher is naturally removed from the natural gas which is then subjected to a selective scrubbing for the removal of hydrogen sulfide with a regeneratable extraction, of scrubbing liquid. Next a C.sub.3 fraction is removed, the remaining gas being scrubbed with a second regeneratable washing agent, for the removal of carbondioxide to leave the methane-rich gas.

Abstract: For the fractionation of a hydrocarbon mixture, e.g., natural gas rich in a C.sub.2+ fraction, the hydrocarbon mixture is partially condensed and the thus-produced gas/liquid mixture is separated in a distillation column to produce a gaseous overhead fraction containing lighter hydrocarbons and a liquid bottoms product containing heavier hydrocarbons. In the upper column section, the gas is scrubbed with a physical scrubbing agent which is preferably a part of the bottoms product. A gaseous stream is withdrawn from the middle of the column to give the C.sub.4+ bottoms product the proper composition for scrubbing purposes. The scrubbing agent is also subcooled to lower the vapor pressure, preferably by a cooler liquid withdrawn from the column.

Abstract: The invention relates to a process for the removal of HCN from gas mixtures that contain at least HCN and sulfur compounds, especially from gas mixtures that are obtained by partial oxidation of hydrocarbons, by catalytic decomposition of HCN, as well as a catalyst for the decomposition of HCN. According to the invention, the gas mixture is brought into contact with a catalyst which decomposes the HCN by hydrogenation and/or by hydrolysis and COS that is contained in the gas mixture is decomposed at least partially in this catalyst by hydrolysis. Advantageously, a catalyst that is based on titanium oxide and/or zirconium oxide as a vehicle and that contains chromium oxide as an active component is used. Advantageously, the catalyst is reduced during catalyst production or before use with H.sub.2 and/or a reducing gas at temperatures above the operating temperature of catalytic decomposition.

Abstract: In a process for the purification of coal gasification gases, synthesis gas and fuel gas are simultaneously produced. In order to obtain a fuel gas rich in CO.sub.2, capable of handling fluctuations in demand, and to produce at the same time a highly concentrated H.sub.2 S fluid fraction, a portion of the crude gas, scrubbed to synthesis gas purity, is utilized for stripping out CO.sub.2 under pressure from scrubbing medium loaded exclusively with CO.sub.2. The partially stripped CO.sub.2 -loaded scrubbing medium is employed for the concentration of sulfur compounds in an H.sub.2 S/COS-loaded scrubbing medium.

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.
