In a combined plant consisting of a fluid production apparatus (P) having a main air compressor (44) and a fluid-consuming unit (2), a gas derived from the unit is expanded in a turbine (10, 20, 30, 40, 150) or another device capable of generating mechanical energy which drives a compressor (14, 24,

In a combined plant consisting of a fluid production apparatus (P) having a main air compressor (44) and a fluid-consuming unit (2), a gas derived from the unit is expanded in a turbine (10, 20, 30, 40, 150) or another device capable of generating mechanical energy which drives a compressor (14, 24, 34, 44, 154.degree. [sic]. Another turbine or device may expand another gas or the same gas derived from the unit so as to drive another compressor.
