KPDN High Purity Nitrogen Air Separation Unit

   Our nitrogen equipment can adoptforward flow and reverse flow, single-tower,double-tower and other process organization methods to meet the requirements of different pressure levels of customers. The whole devicecan be controlled by DCS or PLC system.

What is ASU

Following your specific require to design the machine, liquid phase or gaseous phase, the production of each product. Full set production line which is automatic.Liquid air separation equipment requires more cooling capacity than gas air separation equipment. 

Working Principle

  The basic principle of air separation is use cryogenic rectification to condense air into liquid and separate the air according to the evaporation temperature of each component. The two-stage rectification tower simultaneously obtains pure nitrogen and pure oxygen at the top and bottom of the upper tower. It is also possible to take out liquid oxygen and liquid nitrogen from the evaporation side and the condensation side of the main cooling respectively. The air separation in the rectification tower is divided into two stages, air is separated for the first time in the lower tower to obtain liquid nitrogen and at the same time obtain oxygen-enriched liquid air. The oxygen-enriched liquid air is sent to the upper tower for rectification to obtain pure oxygen and pure nitrogen. The upper tower is divided into two sections: with the liquid-air inlet as the boundary, the upper part is the rectification section, which rectifies the rising gas, recovers the oxygen component, and purifies the nitrogen purity, and the lower section is the stripping section to remove the nitrogen components in the liquid, separated to improve the oxygen purity of the liquid.
