PSA Hydrogen Production Technology
Pressure swing adsorption for hydrogen production utilizes the selective adsorption of non-hydrogen components in hydrogen-rich gas mixtures by adsorbents under pressurized conditions to achieve the separation of hydrogen from other gas components. Meanwhile, the adsorbent releases the adsorbed impurity gases under depressurized conditions, regaining its adsorption capacity.
■ Technical Features
· Small footprint: Rational equipment layout ensures a relatively small footprint compared with similar units.· Stable operation: Capable of continuous non-stop operation throughout the year.
· Higher automation level than similar products: Complete and reasonable control points enable unattended on-site operation.
· Flexible load regulation: Safe and stable operation at a flow rate of 50%–110%.
· Start-stop on demand: Can be started or stopped as required under normal conditions.
■ Main Performance Indicators
· Unit capacity: 400~200,000 Nm³/h· Hydrogen purity: 99%~99.999%
· Operating pressure: 0.5~2.5 MPa (customizable per client requirements)
· Operating temperature: Ambient temperature
