    Abstract: A method and apparatus for liquefying a hydrocarbon stream such as natural gas from a feed stream. A feed stream (10) is provided and passed through at least two cooling stages (2, 4). Each cooling stage involves one or more heat exchangers (12, 14a, 146). One of the heat exchangers (149) involves a first refrigerant circuit (104) having a first refrigerant stream (104a), and a second of the heat exchangers (146) involves a second refrigerant circuit (106) having a second refrigerant stream (106a). The liquefied hydrocarbon stream (50) is expanded and a flash vapour is separated (16) to provide a liquefied hydrocarbon product stream (60) and a gaseous stream (70). The gaseous stream (70), at least a part of the first refrigerant stream (104a), and at least a part of the second refrigerant stream (106a) are passed through a heat exchanger (22), for the gaseous stream to provide cooling to the first and second refrigerant streams.
