Air Products Engineered Membrane Systems

Industrial Engineered Systems Overview
Air Products PRISM Membranes engineers large, industrial membrane systems for nitrogen generation and mixed gas purification. These skid mounted systems are used in the oil and gas industry, ammonia plants, chemical manufacturing facilities, and oil refineries. We work with end users and engineering companies to provide reliable, cost effective, membrane separation solutions.

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.

LifeCycle Solutions
LifeCycle Solutions is the aftermarket and site services unit of PRISM Membranes. Our team of experts will conduct a comprehensive evaluation of your hydrogen membrane system’s performance. We then generate a report with recommendations and work with your team to optimize your hydrogen supply.


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

Petrochemical Plants
Petrochemical PlantsPRISM 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 Synthesis Plant
Ammonia Synthesis PlantThe synthesis loop gas composition includes hydrogen plus high concentrations of methane and argon that accumulate in the synthesis loop. Hydrogen molecules permeate through the membrane and migrate out. This 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.
