Abstract (en)

A partially condensed hydrocarbon feed stream (20) is sent to a column (25). An overhead vapour hydrocarbon stream (30) from the column is then partially condensed by indirect heat exchanging against an expanded cooling fluid flowing through a first section (124) of a cold side heat exchanging channel (120). The cooling fluid consists of a mixed refrigerant composition, and liquid from the expanded cooling fluid is continuously transformed to vapour thereby forming a residual liquid portion of not evaporated expanded cooling fluid. The residual liquid is used to progressively condense the hydrocarbon feed stream (10) to produce the partially condensed hydrocarbon feed stream (20) that is sent to the column, by allowing the hydrocarbon feed stream to lose heat to the residual liquid passing through a second section (126) of the cold side heat exchanging channel. The liquid component that is condensed out of the overhead vapour hydrocarbon stream is used as reflux (47) for the column.
