Oxygen and nitrogen air separation plant is a set of air separation equipment that extracts oxygen and nitrogen from the air at the same time. Cryogenic air separation oxygen production equipment is a new type of turboexpander
Process. The purified incoming air is exchanged with the reflux gas in the main heat exchanger and is gradually cooled to saturated air with a small amount of liquefaction.

Then enter the lower column for rectification. Rectification is the use of oxygen and nitrogen boiling points are different to obtain pure oxygen by multiple partial evaporation and partial condensation in the fractionation column

, the process of pure nitrogen. The function of the lower fractionation column is to produce liquid air and liquid nitrogen. The function of the main condensing evaporator is to evaporate liquid oxygen at different pressures at low pressures

and gas nitrogen condensation, the function of the upper fractionation column is to obtain product oxygen and nitrogen.
