Abstract: The combined production of ammonia and urea by the reaction of gases containing hydrocarbons with steam is conducted by using a steam reformer, downstream secondary reformer, and shift converter. The ammonia synthesis gas (hydrogen, nitrogen and carbon dioxide) is subjected to a high pressure scrubbing step with a physical solvent, to remove the acid impurities, especially CO.sub.2. The pressure on the loaded solvent is reduced to a first intermediate pressure for degasing of the coabsorbed inerts and then to a second intermediate pressure for removal of the bulk of the absorbed CO.sub.2, which is then used for urea synthesis. To remove residual CO.sub.2, the solvent is stripped with air and the resultant air stream containing the stripped residual CO.sub.2 is fed to the secondary reformer.

Abstract: For the purification of hydrocarbon-containing, e.g., methane raw gases containing H.sub.2 S and CO.sub.2, the raw gas is dried, and separated by rectification into a hydrocarbon-rich overhead fraction containing some H.sub.2 S and CO.sub.2 and into a bottom fraction consisting essentially of H.sub.2 S and CO.sub.2. The overhead product is freed, in a first scrubbing column, of the acidic components with a physical acting scrubbing medium selective for H.sub.2 S and COS as against CO.sub.2, e.g., polyethylene glycol ether or toluene. The bottom product from the rectification step is vaporized and selectively desulfurized in a second scrubbing column with the same scrubbing medium, and the scrubbed gas from the second scrubbing column is discharged as CO.sub.2 under pressure.

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: 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.
