摘要： This invention is a method for the recovery of elemental sulfur from a gas mixture containing H.sub.2 S. The gas mixture is first subjected to desulfurization in a Claus installation which has a thermal part and a catalytic part resulting in the recovery of elemental sulfur. Sulfur compounds still contained in the Claus tail gas are then transformed into H.sub.2 S by means of hydrogenation and, if necessary, by means of hydrolysis and the hydrogenated Claus tail gas is subjected to catalytic direct oxidation of the H.sub.2 S to elemental sulfur. The Claus installation comprises exactly one catalytic stage and the catalytic direct oxidation also takes place in exactly one reactor. Sulfur recovery rates of 99.3% to 99.6% are achieved by the method of the invention.

摘要： A process for liquefying a flow of natural gas with simultaneous recovery of a C3/C4-rich fraction is described, whereby the liquefaction of the flow of natural gas is carried out in heat exchange for at least one refrigerant and/or mixed refrigerant flow, and the flow of natural gas that is to be liquefied, after precooling, is subjected to a rectifying column, in which higher hydrocarbons are separated from the flow of natural gas, and then is subjected to further cooling and liquefaction, whereby a C2+-rich fraction that is recovered in the subsequent cooling of the flow of natural gas is fed to the rectifying column as a reflux liquid. According to the invention, a C4/C5-rich fraction (20, 35) is fed directly and/or indirectly to rectifying column (T1) as an additional reflux liquid, whereby the feed point of the C4/C5-rich [fraction (20, 35) is located at the top of rectifying column (T1) or is identical to the feed point of the C2+-rich fraction (5).]
