Abstract (en)
[origin: US2016356547A1] A method and air separation plant for the distillative cryogenic separation of feed air in a distillation column system of an air separation plant at different distillation pressures, wherein all of the feed air in a total air quantity is compressed to a first pressure level that is at least 4 to 5 bar above the highest of the distillation pressures, and from the total air quantity a first part air quantity is first cooled to a first temperature level of 130 to 170 K and then compressed to a second pressure level that is at least 10 bar above the first pressure level, and a second part air quantity is first cooled to a second temperature level of 110 to 150 K and then expanded to a third pressure level that is below the first pressure level.
