    • The generation of electric power and the separation of a feed gas mixture (131) containing oxygen and nitrogen are carried out by combusting an oxidant gas (101) and fuel (109) in a combustion engine (107) to generate shaft work (127) and a hot exhaust gas (111), utilizing the shaft work (127) to drive an electric generator (125) to provide the electric power, compressing (133) the feed gas mixture (131) and separating the resulting compressed feed gas mixture (135) into two or more product gas streams (143,145) with differing compositions, heating one of the product gas streams by indirect heat exchange (119) with the hot exhaust gas (115), and work expanding (155) the resulting heated product gas stream (153) to generate shaft work (159) and yield an expanded product gas stream (161). The feed gas mixture (131) can be air and the combustion engine (107) can be a gas turbine combustion engine, and the air separation process preferably is operated independently of the gas turbine combustion engine.

    • A unit for producing an oxygen gas of a super-high purity by deep freezing of the air, and an object of the present invention is to provide an oxygen gas production unit capable of dispensing with an expansion turbine which is expensive and which often causes troubles. In the unit according to the present invention, a liquid oxygen storage means (23) is connected via an introduction passage (23a) to an upper portion (15) of a rectifier (11) which consists of the upper portion (15) provided with a condenser (16) therein and a lower portion (12) of an intermediate pressure, so as to cool the condenser (16) with liquid oxygen. The compressed air of a super-low temperature is fed into the interior of the lower portion (12) of an intermediate pressure of the rectifier (11) via an air-compressing means (1), an air cooling column (6), an adsorption column (7) and a heat- exchanging means (8), and then cooled with the latent heat of vaporization of a refluxing liquid nitrogen obtained in the condenser (16) to thereby convert the resultant air into liquid air having a higher oxygen content. This liquid air is introduced into the upper portion (15), and the nitrogen is taken out as a gas of an intermediate pressure from the top of the upper portion (15) with the oxygen left therein in a liquid state by utilizing a difference between the boiling points of the two substances. The gasified oxygen obtained from the remaining liquid oxygen is utilized as a product oxygen gas.
