Means for recovering high-pressure hydrogen?
Thread Content
At present, PSA is the primary method used for high-pressure hydrogen recovery in China; the maximum pressure achievable with this method is around 5.6 MPa. Are there any other methods available, such as membrane separation? Can the pressure be increased further? ? Does anyone have a better way?
Membrane separation: 18-20 MPa is no problem
Are there any suitable manufacturers you can recommend? Domestic
Currently, in addition to PSA (Pressure Swing Adsorption) technology, there are indeed other methods for recovering high-pressure hydrogen, such as membrane separation technology. Membrane separation can be carried out under certain pressure, but its upper pressure tolerance is usually lower than that of PSA. In addition, there are also methods for recovering and condensing liquid hydrogen, etc. As for whether higher pressures can be achieved, it depends on the advancements in specific technologies and the pressure resistance of the materials. For the recovery of hydrogen at higher pressures, technological innovation or the use of materials and equipment with higher pressure resistance is required. .
