Abstract
In the fractionation of a gaseous mixture under pressure containing methane, ethane, propane, inert gases, higher hydrocarbons, hydrogen sulfide, as well as carbon dioxide, e.g., a natural gas, the higher hydrocarbons are obtained by rectification as bottoms product, whereas methane, ethane, propane, hydrogen sulfide and carbon dioxide comprise the head product. The rectification is conducted in three stages, wherein the separated head product of the second stage forms at least in part the reflux of the first stage. By means of this process, a C.sub.4+ hydrocarbon condensate free of sour gases, as well as a C.sub.3- head fraction of high purity are obtained.
