Guangdong Province's industrial research project, hosted by Professor Zhu Dongsheng from the School of Chemical Engineering and Energy, South China University of Technology, has passed the appraisal of variable temperature pressure swing adsorption hydrogen purification equipment. The device is driven by a magnetic fan and forced circulation purification outside the hydrogen engine; the process flow is optimized, and the dust removal and degreasing performance of the device is increased; the PLC control system can be used for automatic operation, and has automatic fault determination and processing functions.
According to reports, the technology uses variable temperature and pressure regeneration process and high heat conduction adsorbent to reduce the desorption temperature of the adsorbent to below 200 °C; the direction of gas flow during regeneration is opposite to the direction of gas flow during drying, which improves the regeneration of the adsorbent in the drying tower. The effect and the dryness of hydrogen, the outlet hydrogen dew point can reach below -45 °C. Experts believe that the hydrogen purifier is suitable for the adsorption hydrogen drying process of hydrogen production station, hydrogen-cooled generator set and oxygen plant of smelting plant. It can also be applied to the drying and purification of special gas with appropriate adjustment. It has good market application. prospect.
