Abstract:
The present invention relates to a method of cooling and separating a hydrocarbon stream: (a) passing an hydrocarbon feed stream ( 7 ) through a first cooling and separation stage to provide a methane enriched vapour overhead stream ( 110 ) and a methane depleted liquid stream ( 10 ); (b) passing the methane depleted liquid stream ( 10 ) to a fractionation column ( 200 ) to obtain a bottom condensate stream ( 210 ), a top stream enriched in C1-C2 ( 220 ) and a midstream enriched in C3-C4 ( 230 ), (c) cooling the upper part of the fractionation column ( 201 ) by a condenser ( 206 ), (d) obtaining a split stream ( 112 ) from the methane enriched vapour overhead stream ( 110 ) and obtaining a cooled split stream ( 112′ ) by expansion-cooling the split stream ( 112 ), (e) providing cooling duty to the top of the fractionation column ( 201 ) using the cooled split stream ( 112′ ).

Claim (Index 7):
Method according to  claim 6 , wherein the main overhead stream and the combined stream are cooled in parallel cooling paths in the second cooling stage.
