Abstract
The present invention relates to a method of liquefying a hydrocarbon stream such as a natural gas stream, the method at least comprising the steps of: supplying a partly condensed hydrocarbon feed stream () to a first gas/liquid separator (); separating the feed stream () in the first gas/liquid separator () into a gaseous stream () and a liquid stream (); expanding the gaseous stream () thereby obtaining an expanded stream () and feeding it () into a second gas/liquid separator (); feeding the liquid stream () into the second gas/liquid separator (); removing from the bottom of the second gas/liquid separator a liquid stream () and feeding it into a fractionation column (); removing from the top of the second gas/liquid separator () a gaseous stream () and passing it to a compressor () thereby obtaining a compressed stream (); cooling the compressed stream () thereby obtaining a cooled compressed stream (); heat exchanging the cooled compressed stream () against a stream being downstream of the first gas/liquid separator () and upstream of the fractionation column ().
