The characteristics, process principle and process flow of PSA decarburization technology are basically the same as that of PSA in purifying hydrogen.
The difference lies in that the raw gas of PSA is carbon dioxide-rich mixture and the product gas can be hydrogen, nitrogen, and carbon monoxide.
Decarbonization utilizes the properties of adsorbents that selectively adsorb carbon dioxide from a gas mixture under pressurized conditions to separate carbon dioxide from other gas components.
At the same time, the adsorbent releases the adsorbed carbon dioxide gas under reduced pressure, so that the adsorbent recovers its adsorption capacity. According to the different requirements of customers on the carbon dioxide content of the product, one or two stages of operation are adopted to ensure the yield and stable index of the active ingredients.
CO2 rich feed gas is pretreated and then entered into the PSA system from the bottom of the adsorption tower. Purified gas (H2, N2, CO) is obtained from the top of the tower.
From the bottom of the tower, we get the desorption gas (main content is CO2) so to recover CO2 or release it into the atmosphere.
