In this process, the apparatus for separating the feed gas is connected to the delivery side of at least one variable-rotation-speed compressor, whose speed is controlled on the basis of the measurement of a parameter representative of the flow of gas product. The process is useful in the production of nitrogen from atmospheric air.
