In a process for compressing a gas, associated with a unit (5) for separating a gas mixture, the compressor (1, 2, 7) comprises a number of stages less than that which would be necessary to produce an optimal compressor of the isothermal type compressing the same flow rate of the gas to the same pre

In a process for compressing a gas, associated with a unit (5) for separating a gas mixture, the compressor (1, 2, 7) comprises a number of stages less than that which would be necessary to produce an optimal compressor of the isothermal type compressing the same flow rate of the gas to the same pressure. The compressor may compress the gas mixture to be separated or a product of the separation.

[ We claim:] [1.] Process for separating air by cryogenic distillation, comprising:compressing feed air in a compressor to obtain compressed air;purifying the compressed air in a purification unit by adsorption to obtain purified compressed air;cooling the purified compressed air and separating it in a distillation apparatus;removing a gas stream from the distillation apparatus;warming the gas temperature to a regeneration temperature using compressed feed air having a temperature of at least 100.degree. C. prior to the purification step; andusing the warmed gas stream at the regeneration temperature to regenerate the purification unit.
