Abstract (en)
[origin: EP0641983A1] In this process for producing gaseous oxygen and/or nitrogen under pressure by distillation of air in a double column (9), pumping (at 13) of at least one liquid product withdrawn from the vessel of the low-pressure column (11), and vaporisation (at 8) of the compressed liquid product by heat exchange with air compressed to a high air pressure, all of the air to be distilled is compressed to the high air pressure and the excess fraction of this air is expanded in two series turbines (5, 6) to the pressure of the medium-pressure column (10), the air being partially heated (at 22) between the two turbines. <IMAGE>
