air separation unit process flow diagram

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.

Air Separation Unit Process Flow Diagram Pdf

Large Air Separation Unit Production of large quantities of oxygen and nitrogen Used in a wide variety of fields, large air separation units (ASU) produce high purity oxygen, nitrogen, argon and rare gases through a combination of adsorption purification, cryogenic distillation and internal compression of high pressure products.

Simulation Study of Cryogenic Air Separation Unit Using ...

The cryogenic air separation process is a tight integration of heat exchangers and separation columns which is completely driven by the compression of the air at the inlet of the unit. The air inlet stream is cooled and partially liquified against the leaving product streams. Nitrogen is then separated at a

Technology Handbook - Air Liquide

5. Air separation: The liquid air is separated into oxygen, argon and nitrogen in the distillation columns. The cold gases are fed through the heat exchanger and are warmed- up while the liquids are fed into tank. III. CRYOGENIC METHOD OF AIR SEPARATION Low temperature distillation is the main principle of Cryogenic Air Separation Process.
