    Abstract: A vapor fraction containing hydrogen and at least one hydrocarbon selected from the group consisting of C1 to C4 hydrocarbons is separated from a hydrogen-rich refinery off-gas feed to give a liquid product fraction. The refinery off-gas (1) is fed to and compressed in a compressor/expander (21) having compressor means (20) and expander means (24) mounted and driven on a common shaft (25), and then cooled and partially condensed to form a two-phase fluid (4) in a heat exchanger (22) followed by separation of the vapor (5) and liquid (9) product phases of the fluid in a separator (23) or a separator/fractionation column stabilizer unit (30). The separated vapor phase (5) is transmitted to the compressor/expander unit (21) wherein the vapor is depressurized and partially condensed, thereby driving the compressor (20). The partially condensed depressurized vapor fraction (7) from the expander (24) and, optionally, the liquid phase product fraction (9, 10) from the separator (23) are transmitted in separate streams to the heat exchanger (22) for separate thermal contact with the compressed feed gas (2) wherein the partially condensed depressurized vapor fraction (7) is fully vaporized and the feed gases (2) are cooled. The fully vaporized fraction (8) and the liquid product fraction (13) are recovered in separate streams.

    Abstract: The present invention provides a method for liquefying a hydrocarbon-containing gas stream, comprising cooling the hydrocarbon-containing gas stream (20) in a first heat exchanger (3), wherein the pressure of the cooled hydrocarbon-containing stream (40) is below the cricondenbar being a liquid-vapour multiphase flow and is separated in a liquid bottom stream (50) and a gaseous top stream (60). The gaseous top stream (60) is cooled in an expander (4) and separated in a separator (5) obtaining a gaseous stream (80) and a liquid stream (90). The liquid stream (90) is passed to a pressure reduction and separation stage (91) to obtain one or more further gaseous streams (110, 180) and a liquid hydrocarbon stream (170). The gaseous stream (80) is passed through the first heat exchanger (3) and a compressor obtaining a compressed gas stream (220). At least part of the compressed gas stream (220) obtained in step (h) is combined with the hydrocarbon-containing gas stream (20) provided in step (a). The liquid bottom stream (50) enriched in C3+-hydrocarbons is passed to a NGL-fractionation stage to obtain one or more gaseous streams enriched in C1 and/or C2 which are recycled to at least partially be combined with the hydrocarbon-containing gas stream (20).
