Abstract (en)

[origin: EP0641982A1] All of the entering air is compressed to a high pressure and then cooled to an intermediate temperature. At this temperature, some of the air is turbined (at 4) at medium pressure, and the remainder is liquefied. The low-pressure column operates under a pressure of the order of 1.7 to 5 bar absolute, and its residual gas is expanded in a second turbine (9) after having been heated to ambient temperature then superheated (at 7) by heat exchange with compressed air. Application to the production of impure pressurised oxygen and, simultaneously, of at least one liquid product. <IMAGE>
