Main functions of hydrogen purification

(1) Compared with the traditional process, the pretreatment part of TSA feed gas is added in this device, which can remove most impurities above C5, effectively guarantee the service life of subsequent PSA adsorbents and buffer the changes of feed components.

(2) The 2)VPSA part adopts the 6-2-3 process, that is, two of the six adsorption towers are always in adsorption state, and the pressure is equalized for three times in each cycle and desorbed in vacuum.

(3) The normal temperature deoxidation catalyst is adopted to simplify the process flow.

(4) The automatic control level is high, and it has the functions of accident self-inspection and interlocking treatment, which improves the reliability of the device operation.

(5)PSA program-controlled valve adopts patented products, with small volume, quick action, good sealing performance and long service life.
