Liquid Oxygen Plants

We are engaged in offering excellent quality Liquid Oxygen Plants to our valuable clients.
Process:
The Plant uses normal temperature molecular sieve adsorption, medium pressure booster expansion reflux flow.
Raw air is sucked from the atmosphere,It is going through filter for removal of dust and mechanical impurities.then it is compressed to a certain degree by single stage screw compressori via end stage cooler, air pre-cooling system, the air is cooled to approx. 8. After water separation moisture is separated in water separator and then it goes to purifier for removal of moisture, CO2, C2H2 and hydrogen dioxide.
Then most part of air enters main heat exchanger to be cooled to saturated tempt. and partly is liquefied to the lower part of lower column; another part of air is compressed to a certain degree through two stage compression booster, via end stage cooler enters into oxygen heat exchanger to be cooled to be near saturated temperature, then after throttle goes to lower column. Through lower column pre-distillation we can get enriched oxygen liquid air from the bottom of the column. After cooling through sub-cooler,after throttled it goes to the middle part of upper column as reflux liquid for rectification.
