"THE RECOVERY OF C3+ HYDROCARBONS" Abstract In the recovery of C3+ hydrocarbons from a feed stream containing hydrogen and C1 to at least C5 hydro- carbons, e.g., a refinery waste gas, comprising cooling and partially condensing the feed stream; separating the partially condensed feed stream into a liquid fraction and a gaseous fraction; expanding the gaseous fraction, and fractionating the liquid fraction in a rectification column to obtain product stream consisting essentially of C3+ hydrocarbons and a residual gas stream product con- taining predominantly C2- hydrocarbons, one improvement comprises passing (a) the gaseous fraction prior to expansion; (b) the liquid fraction prior to rectification; and (c) the gaseous fraction after expansion, in indirect heat exchanger relationship with the feed stream to be cooled. Other improvements comprise separate removal of C1 and C2 fractions from the hydrogen gas; the use of a C5+ fraction as a feed to the rectification column and/or as a scrubbing liquid for separating the partially condensed feed stream.
