A b s t r a c t A process for producing nitrogen and oxygen from a precompressed and cooled air comprising compression of air to a pressure of from 0.3 to 0.6 MPa, cooling the compressed air to a saturated state with a partial liquefaction at a temperature of from 90 to 100°K. The cooled air with a par- tial content of the liquid is supplied to separation into at least one vortex pipe. An apparatus for carrying said process comprises a compressor and heat-exchangers positio- ned along the path of movement of the compressed air, which heat-exchangers have a high-pressure cavity and a low-pressu- re cavity, and a vortex pipe having, at one end thereof, an inlet nozzle and a membrane for discharging nitrogen and, at the other end thereof, a diffuser for discharging oxygen. The inlet nozzle of the vortex pipe is connected with the high-pressure cavity of the heat-exchanger, while the vortex pipe membrane - with the low-pressure cavity of the heat-ex- changer. The present invention has the advantage of small size of the apparatus and its workability under the condi- tions of inertional overloads.
