Abstract
A fluid consisting at least partly of a mixture of hydrocarbons is liquefied by means of the following stages: PA1 the mixture under pressure is cooled so as to condense it at least partly to produce a liquid phase and a gas phase, and bringing into contact of at least a fraction of each of said phases is simultaneously achieved at least partly in a countercurrent flow so as to obtain, by matter transfer, a gas phase enriched in light hydrocarbons and a first liquid phase enriched in heavy hydrocarbons, and PA1 the two phases obtained thereby are separated and the gas phase enriched in light hydrocarbons is sent to a second cooling stage in order to obtain a second liquid phase enriched in light hydrocarbons.
