Device name: Pressure swing adsorption decarbonization and hydrogen extraction device
Device scale: 2000-50000Nm³/h
Equipment customers: Shanxi Yangmei Fengxi Chemical Co., Ltd. Linyi Branch, Shanxi Yangmei Fengxi Co., Ltd. Jishan Branch
Process principle:

After the raw material gas enters the adsorption tower of the pressure swing adsorption (PSA) device, the adsorption capacity of the adsorbent in the adsorption bed for carbon dioxide (CO₂) varies with the pressure. When pressurized, the CO₂ in the raw material gas is adsorbed, and the components are not easily adsorbed. (Hydrogen) H₂ and (Nitrogen) N₂ are output from the outlet end of the adsorption bed as purified gas; during decompression and evacuation, the adsorbed CO₂ and other impurity components are desorbed from the adsorbent and the adsorbent is regenerated.
　　According to the specific requirements of users for products, different technological processes can be used to decarbonize and recycle high
Purity CO₂.
Raw gas:

　　 shift gas, coke oven gas, and other gases that need to remove carbon dioxide
Technical index:
