Hydrogen Recovery for Industrial Applications

Using PRISM® Hydrogen Membranes

PRISM® Hydrogen membranes are used to recover hydrogen molecules that are lost in reaction loops or in off-gas streams. The PRISM® Membranes selectively separate hydrogen molecules through a membrane while rejecting the unwanted gas byproducts. The upgraded hydrogen stream can be used for reaction loop feeds or in hydroprocessing, saving the cost of generating or purchasing hydrogen. Production ramp-ups and turndowns are easily managed using simple valves. The passive devices require no maintenance or replacement parts and will process gas streams for years.

using hydrogen pressure swing adsorption

Using Pressure Swing Adsorption (PSA) is another well-established technology to recover hydrogen molecules found in many refinery and large chemical plant off-gas streams. PSA is an amazing technology that removes multiple impurities from a H2 containing gas in one step, and it can produce very pure H2 product of >99.9 to 99.999 vol% H2.
