SEPURAN® Noble Membranes for efficient hydrogen recovery

Evonik's SEPURAN® Noble membrane has been especially developed for hydrogen recovery and purification enabling highly pure hydrogen to be efficiently produced even when inlet concentrations of hydrogen are very low.

Molecular hydrogen can be produced by steam reforming and subsequently by a water gas shift reaction or it occurs as a by-product of different reactions. The largest consumers of hydrogen are refineries as well as ammonia and methanol production facilities.

Hydrogen is used in the most varied chemical reactions. In the case of many of these reactions, the hydrogen used is not fully consumed and can thus be purified and recycled.  The very selective SEPURAN® Noble membrane developed by Evonik enables high product gas purity, a high hydrogen yield as well as reduced energy consumption.
