Document Type and Number:
WIPO Patent Application WO2001044734
Kind Code:
A3
Abstract:
Apparatus (30) for compressing gaseous refrigerant for use in a refrigeration circuit (2) of a liquefaction plant, which refrigeration circuit (2) has an inlet (5), a first outlet (6) for refrigerant at low pressure, a second outlet (7) for refrigerant at intermediate pressure, a third outlet (8) for refrigerant at high pressure and a fourth outlet (9) for refrigerant at high-high pressure, which apparatus (30) comprises a first and a second compressor (31a, 31b), wherein the first compressor (31a) has a main inlet (36) connected to the first outlet (6), a side-inlet (37) connected to the third outlet (8) and an outlet (38) connected to the inlet (5) of the refrigeration circuit (2), and wherein the second compressor (31b) has a main inlet (39) connected to the second outlet (7), a side-inlet (40) connected to the fourth outlet (9) and an outlet (41) connected to the inlet (5) of the refrigeration circuit (2).
