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.
Hydrogen Upgrading with Prism Membranes
PRISM® Hydrogen Membrane Systems recover hydrogen and adjust synthesis gas streams which increases efficiency at oil refineries, petrochemical and ammonia processing plants. In reaction loops, where gas mixtures are cycled through multiple times, PRISM® hydrogen membranes control the buildup of inert byproducts. The upgraded hydrogen is suitable for the reaction feed stream.
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.
