Specifications:

Process:

Air→ Air compressor → Pre-cooler → Purifier →Rectification column and Turbo-expander →liquid oxygen tank or liquid nitrogen tank

Description:

Air enters the suction air filter and after being removed of dust and other mechanical contaminants in it, it is compressed to the pressure of 1.0MPa by air compressor. Air from the air compressor is cooled to 10℃ in the air precooling system and separated condensing water in water separator. after the water being separated its condensed water, taken into the molecular sieve adsorber for removing H2O, C2H2 and CO2.

   Then the cleaned air is divided into two streams, one of them is taken into the rectifying column and cooled by the return waste nitrogen, oxygen,expander air through the main heat exchanger. The steam-liquid air mixture is taken into the lower column for rectifying, and herein the pure nitrogen from the top of the column enters into the evaporator-condenser and condensed by liquid oxygen from the upper column. A part of the liquid nitrogen is fed to the lower column as reflux. The other part after subcooling apart two parts after throttled. One part enters into the top of the upper column,other part enters storage tank as product(LIN).

  Another cleaned stream is compressed in booster end of the booster expansion turbine, then enters the main heat exchanger.  air from the middle and cold end of the main heat exchanger enter into the turbine expansion to generate most refrigeration for need of the plant's operation. After the expanded air return to heat exchange.

The LOX is drawn from oxygen side of the evaporator-condenser, some of them enters storage tank as product.

To meet different demands from customers, different  processes like air cycle process ,nitrogen cycle process, high and low temperature booster turbine expanding processor low temperature refrigerating process etc. are adopted to reduce the power  consumption. In order to achieve stable and reliable operating of plant, PLC control system or DCS control system are recommended.
