| titleOfInvention | Low temperature air separation method and device |
| abstract | Kind Code: A1 Abstract: [PROBLEMS] To provide a low-temperature air separation method and apparatus capable of obtaining high-purity products such as oxygen, nitrogen, and argon in a high yield with the apparatus and operating costs and low energy consumption. A first partial stream of compressed clean air is cooled and introduced into a main rectification unit where it is separated into liquid oxygen and gaseous nitrogen. A crude argon column in which the produced liquid fraction is vaporized by indirect heat exchange with the second partial stream of compressed clean air, and at least part of the second partial stream condensed at that time is connected to the main rectification unit. Used as a refrigerant for the head condenser (27) of (24). The condensed second partial stream serves substantially all of the refrigerant required for the liquefaction of crude argon by the condenser (27). At least part of the second partial stream vaporized by indirect heat exchange in the head condenser (27) of the crude argon column is introduced into the main rectification unit (4) without further pressurization. |
