Title:
METHOD FOR PRODUCING A GAS FROM PRESSURISED AIR BY MEANS OF CRYOGENIC DISTILLATION
Document Type and Number:
WIPO Patent Application WO/2012/131277
Kind Code:
A3
Abstract:
The invention relates to a method for separating air by means of cryogenic distillation in a system of columns, in which two single-stage air superchargers (15, 25) are connected in series and coupled to two turbines (17, 27) which expand the air that was not supercharged. The superchargers supercharge the cooled high-pressure air in an exchange line in which the oxygen from the system of columns is vaporised.
