Pressure swing adsorption hydrogen extraction device
Device name: pressure swing adsorption hydrogen extraction device
Installation scale: 4000Nm³/h
Device customer: Dongying Jiahao Chemical Co., Ltd.
After the hydrogen-containing (H₂) mixed gas enters the adsorption tower of the pressure swing adsorption (PSA) device, the adsorption capacity of the adsorbent in the adsorption bed for each component in the gas mixture varies with pressure, and the raw gas is adsorbed when pressurized The impurity in the adsorbent and the difficult-to-adsorb component (hydrogen) are output as a product from the outlet end of the adsorption bed. During decompression, the adsorbed impurity component is desorbed and desorbed, while the adsorbent is regenerated. At least four adsorbent beds are used for cyclic operation. Realize continuous output of product hydrogen.
