Vaccum Pressure Swing Adsorption

Part  1.Main descriptions of VPSA oxygen plant

1).This plant selectively absorbs the nitrogen in the air by the utilization of molecular sieve, which can absorb and desorb nitrogen according to working pressure. With the air being separated, high purity oxygen can be obtained.

 

2).Specifications

 

 

Performance Index
Oxygen Scale	10~20000 Nm3/h
Oxygen Purity	adjusted in range of 21~95%
Oxygen Consumption	when oxygen purity is 90%, it is 0.32~0.37 KWh/Nm3
Technology Character & Superiority
1 Compared to the same domestic technology, the power consumption is lower than 10~30%.
2 Simple operation and convenient startup and shutdown (the starting time is less than 30 minutes). Less site    area and low maintenance cost and low installation cost. Low civil work cost.
3 Advanced technological process, high-level automation, good operation flexibility and high reliability of long    term operation.

 

 

3). Process Flow:

This set of PSA oxygen generating system mainly consists of air compression, air purification and PSA oxygen production

(1) Air compression: Air is compressed by the air compressor to 0.7-0.8Mpa, which provides continuous and steady air flow and pressure for the oxygen generating system.

(2) Air purification: Compressed air goes through refrigerated air dryer and filter in order to remove water, oil and dust, which prepares to provide the clean air source for the next step PSA.

(3) PSA oxygen production: Purified air goes into the two adsorption towers of PSA oxygen generator after decompression. The loading molecular sieve in the adsorption tower will adsorb the oxygen and set it free. The pure oxygen will go into the next step storage tank.

Part 2.Main Applications And Advantages

 

 

The VPSA oxygen generating is widely used in every field, such as steelmaking, glass smelting, pulp bleaching & paper making, sewage treatment, nonferrous metal smelting, petrochemical engineering, mineral processing, aquiculture, fermentation and drinking water treatment, etc.

 

Compared to large-sized air separation plants, VPSA is featured with less investing capital, energy-saving, less area, stable property, simple operations, and high level of automation.The purity of oxygen, and nitrogen is up to 93% and 99.99%.The plants are designed flexibly, since it can be made according to different requirements and applications.
