    摘要： The invention relates to a method and device for generating two purified partial air streams under different pressures. A total air stream (1) is compressed to a first total air pressure. The compressed total air stream (5) is cooled with cooling water under the first total air pressure by way of heat exchange (4, 6). The heat exchange with cooling water for cooling the total air stream (5) is carried out as a direct heat exchange in a first direct contact cooler (6), at least in part. The cooled total air stream (9) is divided into a first partial air stream (10) and a second partial air stream (11). The first partial air stream (10) is purified in a first purification device (18) under the first total air pressure, generating the first purified partial air stream (19). The second partial air stream (11) is re-compressed to a higher pressure (12), which is higher than the first total air pressure. The re-compressed second partial air stream (14) is cooled with cooling water in a second direct contact cooler (15) by way of direct heat exchange (13, 15). The cooled second partial air stream (17) is purified under the higher pressure in a second purification device (30), thus generating the second purified partial air stream (31).

    摘要： The process and the device serve for cryogenic air fractionation, in particular for supplying an oxygen-enriched (product stream to an oxyfuel power plant. The distillation column system for nitrogen/oxygen separation has a high-pressure column (26) and a low-pressure column (32). The high-pressure column (26) and the low-pressure column (32) are thermally coupled via a condenser-evaporator (37). Feed air (1) is compressed in an air compressor (3), cooled at least in a first post-cooler (6) and purified in a purification device (22), cooled in a main heat exchanger (23a, 23b, 23c) and introduced at least in part (25, 29) into the high-pressure column (26). At least one liquid stream (33, 35) is introduced from the high-pressure column (26) into the low-pressure column (32). An oxygen-enriched product stream (41, 45, 46,47, 48) is taken off from the low-pressure column (32). A first nitrogen stream (63, 64, 65, 66) is withdrawn from the high-pressure column (26) and warmed to a temperature of at least 280 K (6). The warmed first nitrogen stream (67) is work-expanded (72) in a first warm expansion engine (68). The first nitrogen stream (70, 71) which is expanded in the first warm expansion engine (68) is work-expanded in a second warm expansion engine (72).

    摘要： Nitrogen is produced above an offshore hydrocarbon reservoir (12) and injected into the reservoir, by a complex (40) mounted on a previously used vessel hull (16). The vessel weathervanes and the complex includes equipment that takes in ordinary air from a bow end (32) of the vessel, cools the air using sea water pumped into the equipment, and liquefies the oxygen component of air so pure nitrogen remains. The complex also includes injection equipment that heats and pressurizes the pure nitrogen to inject it into the reservoir. The complex is mounted above pipes (24) on the deck (22) of the vessel hull, on spacers (62) so mounting of equipment can be accomplished rapidly and without major alterations to the hull. A riser bundle (150) that extends from the hull to the sea floor, may include both a production riser (152) that carries crude hydrocarbons up to the vessel for storage in hull tanks (20), and an injection riser (160) that carries pressured nitrogen. The lower end of one of the risers is connected to a sea floor pipeline (162) that extends at least 100 meters away from the lower end of the other riser.
