摘要： 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.

摘要： A unit for producing an oxygen gas of a superhigh purity by deep freezing of the air, and an object of the present invention is to obtain a unit which is capable of dealing with sudden variations in the demand for an oxygen gas, by using both an expansion turbine and a liquid oxygen storage means as the refrigerating source. In this unit, a liquid oxygen storage means (23) is connected to an upper portion (14) of a rectifier, provided with a condenser (17) therein, via an introduction passage (23a) so as to cool said condenser with a liquid oxygen, and a lower portion (15) of the rectifier and an expansion turbine (31) for cooling a heat exchanger (7) are connected by an introduction passage (29). The raw compressed air is cooled to a super-low temperature in the heat exchanger, and then fed to the lower portion of the rectifier, in which the resultant air is further cooled with the latent heat of vaporization of a refluxing liquid nitrogen obtained in the condenser, to obtain liquid air having a higher oxygen content. This liquid air is introduced into the upper portion of the rectifier to separate a liquid containing oxygen alone from the liquid air, by utilizing a boiling point difference, and the remainder is discharged to the outside as waste nitrogen. The liquid oxygen is taken out through a conduit (32), and then gasified and taken out as a product oxygen gas through a conduit (35).
