40Nm3/hr PSA Oxygen Plant?

?
Description:
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.

Competitive Advantage:
?
It adopts up-to-date air separation technics flow and reasonable equipment schemes, having the virtues as low working pressure, simple operation, less maintenance fee and good discontinuous running performance.
It adopts the nitrogen-water pre-cooling system with back cooler and regulated packing, needing much less water in the system.-It equips inter-lock device to avoid water into purifier.

TCO Series PSA Oxygen Plant Flow Chart
?
The normal purity oxygen system (90%~93%) is consisted of equipment as followings: (according to user different requirements, may has changes)
?
?
PRESSURE SWING ADSORPTION PROCESS
?
It has 2-vessels filled with Zeolite Molecular Sieves. Clean compressed air at 30o C temp. is passed through 1-vessel and Oxygen comes out as product gas. The other vessel is depressurized to atmospheric pressure and purged with little quantity of Oxygen coming out from other vessel. This regenerates Zeolite Molecular Sieves for use in next cycle. Thus 2-vessels keep cycling alternately in Oxygen production and Regeneration making Oxygen gas available continuously. These units are designed and supplied for 93% to 95% (Max) Oxygen purity.
?
? From PSA design Oxygen pressure is available directly up to 5 Bar (A) without need of booster compressor. So this design is preferred for Low and medium pressure Oxygen requirements.
? It’s very simple in construction and very easy in maintenance and more popular for most Oxygen requirements.
