UIG Air separation plants are designed for a vast range of capacities and products summarized below: FOR OXYGEN 99.7 % AND NITROGEN 99.999%

Specifications:

Two compression methods:

1)Internal compression air separation plants:

Air-Compressed-Pre-cooling-Purifier-Rectification-heart exchanger (low pressure liquid)-Liquid oxygen pump(pressurized liquid oxygen)-oxygen vaporizer - oxygen cylinders

2)External compression air separation plants:

Air-Compressed-Precooling-Purifier-Rectification-heart exchanger (low pressure gas)-oxygen storage-oxygen compressor(pressurized oxygen)-oxygen cylinders

 The main technical specifications of internal compression

Oxygen filling (or booster) with liquid pump.

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 compressor,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. WN is obtained from the top of lower column, after condensed through condenser-evaporator, a part of WN is used as rectification reflux liquid for lower column; another part after cooling through sub-cooler and after throttling goes to the top of upper column as rectification reflux liquid. Pure liquid oxygen is obtained from the bottom of upper column, and it is condensed by condenser-evaporator. Liquid oxygen is abstracted from the bottom after cooling through sub-cooler, then it goes to LOX pump to be pressurized. It is evaporated in O2 heat exchanger and is reheated to normal tempt and then directly goes to oxygen filling ramp for filling of cylinders.

WN from the top of upper column goes through sub-cooler, the ower part of main heat exchanger to be reheated to a certain tempt. Then it goes to expansion turbine to create cold and returns to sub-cooler and main heat exchanger again to be reheated to normal tempt. A part of it passes to purifier as regenerating gas resource and another part goes to be vented partly.

Description:

Process Overview:

1. Air compressors: The air is compressed to 0.5Mpa-0.7Mpa by the air compressor.

2. Pre-cooling: The air in the pre-cooling unit is pre-cooled to 5°C -10°C, 3. Purification: The remaining water, carbon dioxide and hydrocarbons in the air are removed from the purified air of the molecular sieve.

4. Air expansion: The air undergoes expansion refrigeration in the expander to provide the cooling capacity required by the device.

5. Heat exchanger: the aluminum plate fin heat exchanger has light weight and high heat transfer efficiency.

6. Sub-cooling: Liquid air and liquid nitrogen are cooled by the nitrogen and impure nitrogen in the sub-cooler.

7. Distillation: the air is subjected to distillation separation in the lower tower, product nitrogen is obtained in the upper tower, and product oxygen is obtained at the bottom of the upper tower.
