Abstract
The present invention relates to a method of cooling and separating a hydrocarbon stream: (a) passing an hydrocarbon feed stream () through a first cooling and separation stage to provide a methane enriched vapour overhead stream () and a methane depleted liquid stream (); (b) passing the methane depleted liquid stream () to a fractionation column () to obtain a bottom condensate stream (), a top stream enriched in C1-C2 () and a midstream enriched in C3-C4 (), (c) cooling the upper part of the fractionation column () by a condenser (), (d) obtaining a split stream () from the methane enriched vapour overhead stream () and obtaining a cooled split stream (') by expansion-cooling the split stream (), (e) providing cooling duty to the top of the fractionation column () using the cooled split stream (′).
