Abstract (en)
[origin: AU2016269434A1] Abstract Process for obtaining a liquid oxygen-rich and a gaseous oxygen-rich air product in an air separation system, and an air separation system A process is proposed for the low-temperature separation of air, in which an air 5 separation system (100) having a main heat exchanger (3) and a distillation column system (6, 7) is used, which distillation column system comprises a high-pressure column (61) operated at a first pressure level, a low-pressure column (62) operated at a second, lower pressure level, and a mixing column (7). A first compressed-air stream (h) is fed in the gaseous state into the mixing column (7), in particular directly above 10 the sump, and, in the mixing column (7), is sent in counterflow to an oxygen-rich stream (n). The first compressed-air stream (h) is formed using air that is compressed to a starting pressure level above the first pressure level and thereafter is cooled to a first temperature level and is expanded in a first turbine (4). A second compressed-air stream (g) is fed into the high-pressure column (62), which second compressed air 15 stream is likewise formed using the air that is compressed to the starting pressure level and thereafter cooled to the first temperature level and expanded in the first turbine (4). In contrast, a third compressed-air stream (f) is fed into the low-pressure column (62), which third compressed-air stream is formed using air which, although it is likewise compressed to the starting pressure level, is thereafter cooled to a second temperature 20 level, expanded in a second turbine (4) and cooled further in the main heat exchanger (3) to a third temperature level. The air in the first turbine (4) is expanded to the first pressure level and the air in the second turbine (5) is expanded to the second pressure level. The air that is expanded in the first and second turbines (4, 5) is fed to the first turbine (4) at the first temperature level and to the second turbine (5) at the second 25 temperature level, wherein the first temperature level is at least 20 K below the second. The mixing column (7) is operated at the first pressure level or a third pressure level that differs from the first pressure level by at most I bar. A liquid oxygen-rich air product is passed in the liquid state out of the air separation system (100). A corresponding air separation system (100) is likewise subject matter of the present 30 invention. (Figure 1) TD C.0lM crn ix) CCu
