| titleOfInvention | Process and apparatus for recovering pressure oxygen and pressurized nitrogen by cryogenic separation of air |
| abstract | The method and apparatus are for recovering pressure oxygen and pressurized nitrogen by cryogenic separation of air in a nitrogen-oxygen separation distillation column system having at least one pressure column (8). Feed air is compressed in an air compressor (2). The compressed feed air (3, 6) is cooled in a main heat exchanger (20) and at least partially introduced into the pressure column (8). A liquid oxygen stream (11, 12) is taken from the distillation column system for nitrogen-oxygen separation, brought in liquid state to an elevated pressure (13), introduced under this increased pressure in the main heat exchanger (20), in the main heat exchanger (20 ) or pseudo-evaporated and warmed to about ambient temperature and finally recovered as gaseous pressure oxygen product (14). A gaseous circulating nitrogen stream (18, 19) is withdrawn from the distillation column system for nitrogen-oxygen separation and is compressed at least in part (21) in a cycle compressor (22). A first substream of the circulating nitrogen stream (34, 734) compressed in the cycle compressor (22) is brought into indirect heat exchange with the oxygen stream in the main heat exchanger (20) and subsequently expanded (36, 38), the relaxed first substream of the cycle nitrogen stream (37) being at least partially introduced in the liquid state in the distillation column system for nitrogen-oxygen separation. A second partial stream of the cycle nitrogen stream is branched off downstream of the cycle compressor and / or from an intermediate stage of the cycle compressor under a product pressure (P2, P3, P4) and recovered as pressurized nitrogen product (27, 29, 53, 564, 565). A turbine stream (40) formed by a third substream of the circulating nitrogen stream compressed in the cycle compressor (22) is recirculated (41) and at least partially introduced into the nitrogen-oxygen separation distillation column system. |
