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.
