Title:
METHOD FOR PRODUCING METHANE-RICH STREAM AND C2+ HYDROCARBON-RICH STREAM, AND RELATED FACILITY
Document Type and Number:
WIPO Patent Application WO/2011/004123
Kind Code:
A3
Abstract:
Said method includes cooling the supply stream in a first heat exchanger (20), separating in a first disengager (22) so as to produce a light "head" stream (44) and a heavy "foot" stream (45), and dividing the light "head" stream (44) into a dynamic expansion turbine supply fraction (48) and into a supply fraction (46) for a first distillation column (30). The method includes forming a cooled ebb stream (56) from an effluent (54) of a dynamic expansion turbine (26), the portion of the effluent being cooled and at least partially liquefied in a heat exchanger (28). The method includes placing the cooled ebb stream (56) of the heat exchanger (28) into the first distillation column (30).
