Abstract

The invention relates to a method for the production of at least one gas from air by cryogenic distillation in at least a first operating mode, in which an auxiliary turbine (27) sucks a gaseous fraction of the air flow which has been cooled down in the main exchange line (7), the suction pressure of the auxiliary turbine is substantially greater than or equal to the average pressure, and a portion of the air constituents is produced in a liquid form as a final product while, in a second operating mode, the air flow processed in the auxiliary turbine is reduced and the production of liquid as a final product is decreased.
