Hydrogen separation under high pressure
Thread Content
How can hydrogen separation be achieved under high pressures, such as those of 20 MPa or more? Existing methods like membrane separation, hydration separation, cryogenic separation, and pressure swing adsorption cannot handle such high pressures
Fractionation can be used! The pressure exerted on distillation towers is generally above several dozen megapascals.
Could you be more specific? Thank you 2# lilull2008
High pressure can be used for hydrogen separation through membrane separation; it is not related to pressure per se. Membrane separation simply has certain limitations regarding the pressure difference, and it seems to be able to withstand a pressure difference of 10 MPa.
