PSA

PSA Carbon Dioxide Gas Recovery and Purification systems

CO2-PSA PSA Carbon Dioxide Gas Generators

System easily and economically recovers high-purity CO2(99% or more) from a raw gas containing CO2 such as combustion exhaust gas in 1987, we commercialized this system first in the world and achieved the output capacity of 3,000 m3/h(nor.) as commercial plant. In addition, our CO2 liquefaction plant economically liquefies CO2 recovered by our CO2 PSA system. This plant is acclaimed in various industries.

Contents
Principle CO2 is adsorbed much more than N2. By utilizing this characteristic, the adsorbed CO2 is desorbed by a vacuum pump for recovery of high-purity CO2. (Patented)
Features 1.CO2 can be obtained economically.
The cost is approx. 1/2 to 1/3 of purchase cost of liquid CO2 on a tank truck basis.
2.CO2 concentrated over 99% can be obtained continuously.
3.Low running cost.
The running cost is lower than that of the conventional chemical adsorption process which consumes a great amount of steam.
4.Product CO2 can be obtained immediately after start-up.
General Specification Capacity: 3,000m3/h(nor.) per unit
Purity: 99%
Pressure: 0.069 to 2.45MPaG
Moisture: Dew point −10℃
