Title:
PROCESS AND APPARATUS FOR PRODUCING GASEOUS OXYGEN BY CRYOGENIC DISTILLATION OF AIR
Document Type and Number:
WIPO Patent Application WO/2015/040306
Kind Code:
A3
Abstract:
Process for producing gaseous oxygen by cryogenic distillation of air in which a portion (15) of the feed air flow is brought to a pressure P1, by means of a first compressor (1), the suction temperature T0 of which is between 0 and 50°C, the gas at the pressure P1 is cooled, in order to generate a stream of air at the pressure P1 and the temperature T1 between 5°C and 45°C, a portion (17, 19) of the air compressed in the first compressor undergoes an additional compression step starting from the temperature T1 and from the pressure P1 to a pressure P2 greater than P1, then is cooled, to the temperature T2 where T2 and T1 differ by less than 10°C.
