Abstract:
An improved process for separating a hydrocarbon bearing feed gas containing methane and lighter, C(ethylene and/or ethane), and heavier components into a fraction containing predominantly methane and lighter components and a fraction containing predominantly Cand heavier hydrocarbon components including the steps of cooling and partially condensing and delivering the feed stream to a separator to provide a first residue vapor and a first liquid containing C, directing a first part of the first liquid containing Cinto a heavy-ends fractionation column wherein the liquid is separated into a second hydrocarbon bearing vapor residue and a second liquid product containing C; further cooling the second part of the first liquid containing Cand partially condensing the second hydrocarbon bearing vapor residue; combining the cooled second part of the first liquid and partially condensed second hydrocarbon-bearing vapor residue and directing them to a second separator effecting a third residue and a third liquid; cooling and directing a first part of the third liquid into the lights-ends fractionation column, to thereby condense C's and heavier components while the methane is evaporated in the light-ends fractionation column to thereby obtain fourth residue vapor and liquid, heating and supplying the fourth liquid recovered from the light-ends fractionation column to the heavy-ends fractionation column as a feed thereto; conducting the second part of the third liquid to the heavy-ends fractionation column as a feed thereto.

Abstract:
A process for separating a hydrocarbon gas into a fraction containing a predominant portion of the methane or ethane and lighter components and a fraction containing a predominant portion of the C2 or C3 and heavier components in which 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 C2 or C3-containing liquid; and C2 or C3-containing liquids at substantially the pressure of separation are directed into a distillation column wherein the liquid is separated into a second residue to recover a C2 or C3-containing product. A portion of the vapor and/or a portion of the liquid from the first hydrocarbon vapor/liquid separation is further cooled and introduced into a fractionation column to increase the C2 or C3 and heavier hydrocarbons recovery from the natural gas stream.

Abstract:
An improved process for separating a hydrocarbon bearing feed gas containing methane and lighter, C. sub. 2 (ethylene and ethane) and heavier components into a fraction containing predominantly methane and lighter components and a fraction containing predominantly C. sub. 2 and heavier hydrocarbon components including the steps of cooling and partially condensing and delivering the feed stream to a separator to provide a first residue vapor and a C. sub. 2 containing liquid, directing a portion of the C. sub. 2 containing liquid into a heavy ends fractionation column wherein the liquid is separated into a second hydrocarbon bearing vapor residue and a C. sub. 2 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 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 C. sub. 2 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 C. sub. 2 and heavier components while the methane itself is evaporated in the light ends fractionation column.
