摘要： A method and apparatus for liquefying a hydrocarbon stream such as natural gas from a feed stream. A feed stream is provided and passed through at least two cooling stages. Each cooling stage involves one or more heat exchangers. One of the heat exchangers involves a first refrigerant circuit having a first refrigerant stream, and a second of the heat exchangers involves a second refrigerant circuit having a second refrigerant stream. The liquefied hydrocarbon stream is expanded and a flash vapor is separated to provide a liquefied hydrocarbon product stream and a gaseous stream. The gaseous stream, at least a part of the first refrigerant stream, and at least a part of the second refrigerant stream are passed through a heat exchanger, for the gaseous stream to provide cooling to the first and second refrigerant streams.

摘要： First and second multi-phase streams are processed in first and second trains that are structurally different from each other such that the first and second trains have different operating conditions. The first and second trains produce first and second gaseous hydrocarbon streams and first and second liquid hydrocarbon component streams. The first and second gaseous hydrocarbon streams are combined downstream of the first and second trains to provide a combined gaseous hydrocarbon component stream.

摘要： In a method and apparatus for passing a mixed vapour and liquid stream between a first heat exchanger (101) and a second heat exchanger (102) the mixed vapour and liquid stream outflows from the first heat exchanger (101) through two or more outlets (104). Then, the mixed vapour and liquid stream in the outlets (104) passes through two or more intermediate conduits (103) to the second heat exchanger (102), after which the mixed vapour and liquid stream inflows from the intermediate conduits (103) into the second heat exchanger (102) through two or more inlets (105). The number (X) of outlets (104) is equal to or greater than the number (Y) of inlets (105).
