The technical of Purification of hydrogen by pressure swing adsorption

Hydrogen containing gas mixture into the PSA adsorption tower, the adsorption bed adsorbent on adsorption capacity of each gas mixture in the with the change of pressure difference, pressure when the adsorption of impurities in the raw material gas, is not easy to absorb the components of hydrogen from the outlet end of the adsorption bed as the product output, decompression. The adsorption of impurities The components were desorbed and desorbed while the adsorbent was regenerated. At least four adsorption beds are used to achieve continuous hydrogen output。

Working principle:

Hydrogen containing gas mixture into the PSA adsorption tower, the adsorption bed adsorbent on adsorption capacity of each gas mixture in the with the change of pressure difference, pressure when the adsorption of impurities in the raw material gas, is not easy to absorb the components of hydrogen from the outlet end of the adsorption bed as the product output, decompression. The adsorption of impurities The components were desorbed and desorbed while the adsorbent was regenerated. At least four adsorption beds are used to achieve continuous hydrogen output。


Control mode and characteristics:

Control mode: The SPA device is controlled by the controller and meter. The controller can select DCS, FCS and PLC control system according to the scale and control requirements of the SPA device。

Characteristics: It not only realizes the conventional control of the system, but also realizes the expert control and adaptive optimization control of arbitrary combination and switching of multiple towers, which not only improves the operational flexibility of the device, but also ensures the long-term, stable and safe operation of the PSA device。
