Abstract:
1. An apparatus for obtaining a light hydrocarbon enriched liquid fraction comprising means for introducing feedstock at least one absorber (C 1 ) comprising means for withdrawing a liquid effluent ( 3 ), at least one cold separator means (D 1 ) for separating a gaseous phase ( 8 ) and for feeding the separated gaseous phase ( 8 ) to the absorber (C 1 ); means for mixing at least a portion of said withdrawn liquid effluent ( 3 ) with feedstock ( 1 ), at least one cooling means (RF 1 ) for cooling resultant mixture of said at least one portion of liquid effluent ( 3 ) and feedstock ( 3 ); at least one means for recycling to said cold separators the resultant cooled mixture containing feedstock and at least a portion of the liquid effluent ( 3 ) obtained from the absorber, at least one means for recovery ( 9 , 10 ) of a light hydrocarbon-enriched liquid fraction obtained from said cold separator and at least one means ( 7 ) for evacuation of unabsorbed gases from said at least one absorber (C 1 ).
