摘要： In a method of treating a hydrocarbon stream, such as a natural gas stream, a partly condensed feed stream (10) is supplied to a first gas/liquid separator (2), where it is separated into a gaseous stream (20) and a liquid stream (30). The liquid stream (30) is expanded and fed (40) into a second gas/liquid separator (3), and the gaseous stream (20) is split into at least two sub-streams (50, 70). A first sub-stream (50) of the at least two sub-streams is expanded, thereby obtaining an at least partially condensed first sub-stream (60), and subsequently fed (60) into the second gas/liquid separator (3). A second sub-stream (70) of the at least two sub-streams is cooled against a cold stream (120), thereby obtaining an at least partially condensed second sub-stream (90, 90a), which is fed (90, 90a) into the second gas/liquid separator (3) from which a gaseous stream (130) and a liquid stream (100, 100a) are removed. The at least partially condensed second sub-stream (90, 90a) may have a temperature of below −95° C.
