摘要： A natural gas liquefaction process comprises passing natural gas through a series of heat exchangers (150, 151, 153) in countercurrent relationship with a gaseous refrigerant circulated through work expansion cycle. The work expansion cycle comprises compressing the refrigerant, dividing and cooling the refrigerant to produce at least first and second cooled refrigerant streams (126, 128), substantially isentropically expanding the first refrigerant stream (126) to a coolest refrigerant temperature, substantially isentropically expanding the second refrigerant stream (128) to an intermediate refrigerant temperature warmer than said coolest refrigerant temperature, and delivering the refrigerant in the first and second refrigerant streams (126, 128) to a respective heat exchanger (153, 151) for cooling the natural gas through corresponding temperature ranges. The refrigerant in the first stream (126) is isentropically expanded to a pressure at least 10 times greater than the total pressure drop of the first refrigerant stream across said series of heat exchangers (150, 151, 153), said pressure being in the range of 1.2 to 2.5 MPa.

摘要： C 2 and C 3 hydrocarbons, particularly ethylene and propylene, are recovered from refinery or petrochemical plant gas mixtures by cooling and fractionating a feed gas mixture containing these hydrocarbons and lighter components. Refrigeration for the process is provided by a closed-loop gas expander (147) refrigeration process cycle which preferably uses nitrogen as the recirculating refrigerant. Cooling and fractionation may be effected in a dephlegmator (121).

摘要： A process for producing a liquefied natural product such as LNG is described where a single phase nitrogen refrigerant is used in such a way that the refrigerant stream (10) is divided into at least two separate portions (12, 14) which are passed through separate turbo-expanders (106, 108) before being admitted to separate heat exchangers (103, 104) so that the warming curve of the refrigerant more closely matches the cooling curve of the product being liquefied so as to minimise thermodynamic inefficiencies and hence power requirements involved in operation of the method.

摘要： Volatile organic compounds and water vapor are recovered from a low-boiling gas by compressing the gas to an elevated pressure and cooling the gas in stages to condense volatile components and water while avoiding freezing in the system. Operating the system at an elevated pressure increases condensation efficiency, reduces the number of stages required, and minimizes operating problems to avoid freezing.

摘要： A method for the recovery of hydrogen and one or more hydrocarbons having one or more carbon atoms from a feed gas (101) containing hydrogen and the one or more hydrocarbons, which process comprises cooling and partially condensing (103) the feed gas (101) to provide a partially condensed feed (105); separating (107) the partially condensed feed to provide a first liquid stream (109) enriched in the one or more hydrocarbons and a first vapor stream (111) enriched in hydrogen; further cooling and partially condensing (123) the first vapor stream to provide an intermediate two-phase stream (125); and separating (127) the intermediate two-phase stream to yield a further-enriched hydrogen stream (129) and a hydrogen-depleted residual hydrocarbon stream (131). Some or all of the cooling is provided by indirect heat exchange (103,123) with cold gas refrigerant generated in a closed-loop gas expander refrigeration cycle (143,150,153,139,141).
