Air Separation Linde US Engineering. Air separation by rectification in a single/double column: Using his air liquefaction principle as a basis, Carl von Linde constructed the first air separation plant for oxygen production in 1902 using a single column rectification system. In 1910, he set the basis for the cryogenic air separation principle with the development of a double, Air Separation Plant Capacities: The Oxygen Plant Having The Following Machineries And Equipments: 1. Distillation Column The separation of air into its constituent parts at high purity requires a cryogenic distillation process. To achieve the low distillation temperatures a modern air separation unit requires a refrigeration cycle, and the cold equipment has to be kept within an insulated.

An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is fractional distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon. Cryogenic air separation takes advantage of the differing boiling points of its components as shown in Table 1. In order to start the separation process, a large quantity of the incoming air needs to be liquefied. This is accomplished by cooling the air by decreasing its temperature and manipulating the pressure until condensation begins
