Hydrogen Recovery by Membrane Technology

Membrane hydrogen recovery units produce a gas stream enriched to a hydrogen content of 90–99.9% that can be returned to production. In many cases, membrane hydrogen concentration plants are used where the use of equipment based on other technologies is not possible or not technically feasible.
