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.
