摘要： Method and apparatus of separating an oxygen and nitrogen containing feed stream, for example, air, in higher and lower pressure columns. A crude liquid oxygen stream condenses nitrogen vapor in the higher pressure column for reflux purposes and results in the partial vaporization of the crude liquid oxygen stream to produce vapor and liquid fractions thereof. The liquid fraction condenses a lower pressure part of the feed stream and results in the liquid fraction being at least partially vaporized. Both the vapor fraction of the crude liquid oxygen stream and the liquid fraction after having been at least partially vaporized are introduced into the lower pressure column. Boil-up is produced within a bottom region of the lower pressure column by partially vaporizing an oxygen-rich liquid column bottoms against condensing a higher pressure part of the feed stream and then utilizing vapor or residual liquid as an oxygen product.

摘要： A first stream of compressed, cooled air is introduced into a higher pressure rectification column 12 through an inlet 14 and is separated into nitrogen vapour and oxygen-enriched liquid. At least some of the nitrogen vapour is condensed in a condenser 22 and one stream of the resulting liquid nitrogen is used as reflux in the column 12 and another stream as reflux in a lower pressure rectification column 30. Oxygen enriched liquid withdrawn from the column 12 through an outlet 32 is separated in the column 30. Impure liquid oxygen product is withdrawn form the column 30 through an outlet 52. A less pure stream of liquid oxygen is withdrawn from the column 30 through an outlet 48, is reboiled in a condenser-reboiler 16 by indirect heat exchange with a second stream of air and is reintroduced into the column 30 at its bottom through an inlet 51.

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).

摘要： Method and apparatus of separating an oxygen and nitrogen containing feed stream, for example, air, in higher and lower pressure columns. A crude liquid oxygen stream condenses nitrogen vapor in the higher pressure column for reflux purposes and results in the partial vaporization of the crude liquid oxygen stream to produce vapor and liquid fractions thereof. The liquid fraction condenses a lower pressure part of the feed stream and results in the liquid fraction being at least partially vaporized. Both the vapor fraction of the crude liquid oxygen stream and the liquid fraction after having been at least partially vaporized are introduced into the lower pressure column. Boil-up is produced within a bottom region of the lower pressure column by partially vaporizing an oxygen-rich liquid column bottoms against condensing a higher pressure part of the feed stream and then utilizing vapor or residual liquid as an oxygen product.
