Prism® Membranes

Systems are scalable and customizable for specific operating or capital requirements.

For refinery operations, PRISM Membrane Systems recover hydrogen within hydro-processing applications at oil refineries. They reject the inert compounds that build up in hydrogen recycle loops. This means that less manufactured hydrogen is required to maintain the hydrogen balance in the system and the process becomes less costly to operate.

In petrochemical plants, PRISM Membrane Systems recover hydrogen and adjust synthesis gas streams to provide maximum efficiency. Processes include: hydrogen recovery from methanol plant purge streams, synthesis gas ratio adjustment, carbon monoxide purification, hydrogenation purge streams, and hydrogen recovery from PSA purge gas.

Ammonia syntheses processes benefit when the synthesis loop gas has inert byproducts removed. This gas composition includes hydrogen plus high concentrations of methane and argon that accumulate in normal operations. Hydrogen molecules permeate through the membrane and migrate out and the upgraded hydrogen stream is returned to the synthesis loop to supplement the feed stock of synthesis gas. This means that less manufactured hydrogen is required to maintain the hydrogen balance in the system and the process becomes less costly to operate.
