Process Gas Systems

 

Membrane-based process gas recovery and purification systems provide an economical and durable solution for refining and petrochemical facilities. Applications include hydrogen recovery, hydrogen purification, carbon monoxide purification, and syngas ratio adjustment. Each system is delivered on a small footprint skid and requires very little maintenance or operator attention.

 

Over 500 PRISM® Membrane systems have been sold for critical gas separation applications. Our product engineering team is ready to design, engineer, and build a system to meet your unique requirements.

 

 

PRISM Hydrogen Membranes for Petrochemical Plants

PRISM Membrane Systems recover hydrogen and adjust synthesis gas streams to provide maximum efficiency at petrochemical processing plants. The membrane separators use selective permeation to recover and purify valuable hydrogen or reject inert byproducts from high-pressure petrochemical streams. Petrochemical 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.

PRISM Hydrogen Membranes for Ammonia Synthesis Plants

PRISM Membrane Systems increase the efficiency of ammonia plants by recovering hydrogen from purge gas streams.

 

PRISM Membranes recover 90% of the hydrogen in the purge gas to increase ammonia production. The system is easily adjusted to meet fluctuating production of the ammonia plant. The membrane systems treat the purge stream by recovering ammonia as the product and returning the hydrogen to the synthesis loop. The system usually includes a water scrubber to recover ammonia lost in the purge.
