What is PSA?
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 CO2 rich mixture and the product gas can be H2, N2 as well as CO.
Production technology is mature and operation is reliable
The process flow is simplified and easy to operate accompanied by a prompt action for both start-up and shut-down
Automation is high, and the operation and control are simple and reliable
Operation is stable, safe and reliable
Less land occupation and investment can be recovered in a short time
Cost-effective in operation and production
Recover CO2 with high concentration >90%
De-carbonization separates carbon dioxide from other gaseous components by utilizing the nature of adsorbent which is selected adsorption of carbon dioxide in gas mixture under pressurized condition.
At the same time, adsorbents release adsorbed carbon dioxide gas under the depressurizing conditions to enable adsorbents to regain adsorbing capacity.
One stage or two stages of operation are adopted based on the client’s different requirements for the contents of carbon dioxide as a product so as to ensure the yield of valid components and stable index.
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.
