Abstract (en)

A hydrocarbon stream of a composition comprising methane, ethane, and one or more hydrocarbon components heavier than ethane is provided (10). A side portion (70) of the hydrocarbon stream having the same composition as the hydrocarbon stream is selectively branched off, whereby a main portion of the hydrocarbon stream passes to a liquefaction system (15). The side portion is passed to an extraction unit (200) where an ethane-enriched stream is extracted from the side portion, which ethane-enriched stream contains a higher relative amount of ethane than the side portion. the ethane-enriched stream is passed to a storage tank where it forms an accumulated amount of the ethane-enriched stream which is stored for subsequent use as a refrigerant fluid (150) in the liquefaction system.
