摘要： An improved process for separating a hydrocarbon bearing feed gas containing methane and lighter, C₂ (ethylene & ethane) and heavier components into a fraction containing predominantly methane and lighter components and a fraction containing predominantly C₂ and heavier hydrocarbon components including the steps of cooling and partially condensing and delivering the feed stream to a separator (44) to provide a first residue vapor and a C₂-containing liquid, directing a portion of the C₂-containing liquid into a heavy ends fractionation column (56) wherein the liquid is separated into a second hydrocarbon bearing vapor residue and a C₂ containing product, conducting a portion of the first residue vapors with at least part of the partially condensed second residue into a light ends fractionating column (52) to thereby obtain third residue vapors and liquids, supplying the liquids recovered from the light ends fractionating column to the heavy ends fractionation column as the liquid feed thereto and directing part of the C₂ containing liquid from the first step into intimate contact with the second residue, which liquid provides additional liquefied methane which acts with the partially condensed second residue as a direct contact refrigerant to thereby condense C₂ and heavier components while the methane itself is evaporated in the light ends fractionation column.

摘要： The present invention relates to a process for separating a hydrocarbon gas into a fraction containing a predominant portion of the ethane and lighter components and a fraction containing a predominant portion of the C.sub.3 and heavier components in which process the feed gas is treated in one or more heat exchange, and expansion steps; partly condensed feed gas is directed into a separator wherein a first residue vapor is separated from a C.sub.3 -containing liquid; and C.sub.3 -containing liquids, at substantially the pressure of separation, are directed into a distillation column wherein said liquid is separated into a second residue is separated to recover a C.sub.3 -containing product. The foregoing process is improved by cooling said second residue to partially condense it; directing the partially condensed second residue into said separator forming thereby a liquid portion and a vapor portion; intimately contacting at least the first residue vapor with at least the liquids portion of the partly condensed second residue in at least one contacting stage within said separator, and thereafter separating the vapors and liquids from said contacting stage; supplying the liquids thereby recovered to the distillation column as a top liquid feed thereto; and directing the vapors thereby recovered into heat exchange relation with said second residue from the fractionation column, and thereafter discharging said residue gases.
