Reliable Gas Separation PSA Plant With Pressure Swing Adsorption System

According to customers’ specific requirements and productioncharacteristics, the most appropriate technical plan, processroute, adsorbents types and proportion are provided to ensure theyield of effective gas and the reliability of index.

Dense filling technology of adsorbents is adopted to further reducethe dead spaces between the bed layers and increasing the recoveryrate of the effective components.

In the operation plan, mature and advanced control software packageis adopted to optimize the adsorption time, which enables the plantto operate in the most economical mode for a long time and be freefrom the influence of technical level and careless operation ofoperators.

The lifespan of our PSA programmable valves with specialtechnologies is above 1 million times.

1. CO2 Separation and purification (PSA - CO2)
To recycle pure CO2is recycled from CO2-rich gas mixture. Materialgases include: such as exhaust gas of lime kiln, fermentation gas,converted gas, natural mine gas and other gas sources with CO2.with CO2, with tThe purity of the recycled CO2 reaching can reach98~99.99%.

2. H2 Recycling from H2-rich gas mixture
To Recyclerecycle pure H2 from H2-rich gas mixture such asconverted gas, refined gas, semi-water gas, city gas, coke-ovengas, fermentation gas, methanol tail gas, formaldehyde tail gas,FCC dry gas of oil refinery, converted tail gas and other gassources with H2, . with the purity of H2 reaching 98 - 99.999%.Thepurity of the recycled H2 can reach 98~99.999%
3. CO Separation and Purification (PSA - CO)
To recycle pure CO is recycled from CO-rich gas mixture. Materialgases include: such as semi-water gas, water gas, blast furnace gasof cuprammonia regenerated gas, yellow phosphorus tail gas andother gas sources with CO, . The purity of the recycled CO canreachwith the purity of CO reaching 80~99.9%.

4. CO2 Removal (PSA - CO2 Removal)
Remove CO2 from converted gas. which It is applied fordecarbonization of synthetic ammonia and methanol production, aswell as other CO2-removal cases.

5. CH4 Concentration and Purification from Biogas
This technology is to get high purity CH4 from CH4-rich biogas bysuccessively conduct compression and desulfurization, and removeforeign gases by PSA technology.

6. Hydrocarbons above C2 Removal (PSA - C2 Removal)
Remove the hydrocarbon above C2 from natural gas and oilfield gas,for producing pure CH4.
