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).

摘要： The method and the device serve to produce oxygen by the low-temperature separation of air at variable energy consumption. A distillation column system comprises a high-pressure column (34), a low-pressure column (35) and a main condenser (36), a secondary condenser (26) and a supplementary condenser (37). Gaseous nitrogen (41, 42) from the high-pressure column (34) is liquefied in the main condenser (36) in indirect heat exchange with an intermediate liquid (43) from the low-pressure column (35). A first liquid oxygen stream (70) from the bottom of the low-pressure column (35) is evaporated in the secondary condenser (26) in indirect heat exchange with feed air (25b) to obtain a gaseous oxygen product (72). The supplementary condenser serves as a bottom heating device for the low-pressure column (35) and is heated by means of a first nitrogen stream (44) from the distillation column system, which nitrogen stream was compressed previously in a cold compressor (45). In a second operating mode of lower energy consumption, less feed air (1) is compressed in the main air compressor (3) of the installation to a lower pressure compared to a first operating mode of higher energy consumption, less liquid oxygen (70) from the low-pressure column (35) is passed into the secondary condenser (26) and more nitrogen is compressed in the cold compressor (45). Furthermore, in the second operating mode, a second liquid oxygen stream (73) is additionally passed into the secondary condenser (26).
