1.Features of the plant:

 

a.Purifying air by molecular sieve adsorption makes the process simple, start-up and operation easy and safe, switch-over loss small and rectifying condition stable.

 

b. By using the pre-cooling system to cool the air with normal temp. Thus it makes the molecular sieve adsorbent in good condition.

 

c.For the use of the automatically controlled filter, the air bearings turbo-expander and the aluminum

plate-fin heat exchanger, the stability, safety and reliability of the whole plant are improved greatly.

 

d.By using a new construction of the evaporator-condenser to avoid the accumulation of C-H chemical compounds.

2.Process Description of Liquid Nitrogen/Oxygen Plant

 

a.air compression and pre-filter system: air is compressed by screw compressor. Then part of free water and oil is removed by the following oil-water separator

 

b.Air pre-cooling purification system: After compression and water separation, air enters the pre-cooling unitand be pre-cooled. Then it enters into two stage of fine filter to further filter out water, oil and gas.

 

 c.Air purification system:After pre-cooling and purification, air enters into the molecular sieve purification system, Gaseous impurities such as the remaining water, carbon dioxide are removed by molecular sieve absorption

 

d.Distillation system:After pre-cooling and purification, basically, the air can be considered to be a mixture of oxygen and nitrogen.It then enters into the distillation system in the fractionating tower, after expansion refrigeration, distillation of liquefied; we can get the liquid product of 99.7% oxygen and 99.999% nitrogen

 

e.Liquid reserves pressurization system:Liquid oxygen and nitrogen products are sent into the cryogenic liquid storage tank for storage after coming out from the fractionation tower. They are pressured according to the user need through the liquid pump. After that they are directly bottle filled or sent to users after entering the air heated vaporizer for gasification.
