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.

Oxygen filling(or booster)with oxygen compressor.

 

Description:

 

•External compression air separation plant:

Air-Compressed-Pre-cooling-Purifier-Rectification-heat exchanger (low pressure gas)-oxygen storage-oxygen compressor(pressurized oxygen)-oxygen cylinders or Pipeline supply.

• Basic configuration of this air separation plant:

  (1) Air compressor (Oil lubrication screw type or oil-free type)        1 set

  (2) Air pre-cooling unit (Close frame structure)            1 set

  (3) Molecular sieve purification system                  1 set

  (4) Rectification column system (Cold Box)              1 set

  (5)Turbo expander                                   1 set                                                   

  6) oxygen storage                                    1set

7)oxygen compressor                               1set  

8)Instruments & electrical system                     1 set

•For the purpose of safety operation for long time, certain liquid in condenser-vaporizer are drawn out of column regularly, by doing so, it can be avoid the accumulation of hydrocarbon, especially for acetylene.

 

Applications:

 

we supplied to many countries (Russia, Kazakhstan, Tajikistan, India, Bangladesh, Thailand, Philippines, North Korea, Mongolia, Equatorial Guinea, Botswana, Zambia, Angola, Tanzania) .

Competitive Advantage:

 

High reliability. Low pressure process. Low power consumption. Short time delivery. Good service.
