    摘要： A method and apparatus for separating air in which a compressed and purified air stream is cooled in a main heat exchanger. Thereafter, the compressed and purified air is separated in a distillation column system to produce product streams. The product streams warm within the main heat exchanger by indirectly exchanging heat with the compressed and purified air stream. One or more of the product streams is distributed to a plurality of vortex tubes at successively warmer temperatures so that warm and cold streams produced thereby become successively warmer and one or more of the warm streams has a temperature warmer than that of said compressed and purified air stream upon its introduction into said main heat exchanger. All but the warm stream(s) having the warmer temperature are recycled back to said main heat exchanger to participate in the indirect heat exchange and heat is rejected by discharging said warm stream(s) so that heat is rejected at the warmer temperature and refrigeration is produced.

    摘要： 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.degree. to 100.degree. K. The cooled air with a partial content of the liquid is supplied to separation into at least one vortex tube.An apparatus for carrying said process comprises a compressor (1) and heat-exchangers (2) positioned along the path of movement of the compressed air, which heat-exchangers have a high-pressure cavity and a low-pressure cavity, and a vortex tube (4) having, at one end thereof, an inlet nozzle (5) and a diaphragm (6) for discharging nitrogen and, at the other end thereof, a diffuser (7) for discharging oxygen. The inlet nozzle (5) of the vortex tube (4) is connected with the high-pressure cavity of the heat-exchanger (2), while the diaphragm (6) of the vortex pipe (4) is connected with the low-pressure cavity of the heat-exchanger (2).
