UOP’s Polybed PSA sets the industry standard for H2 purification and recovery


For hydrogen recovery/purification applications where the feed stream is at low to intermediate pressure (<1000 psig) and where downstream process requirements require minimum pressure reduction and high purity hydrogen product, Pressure Swing Adsorption (PSA) technology is the process of choice. UOP’s market leading Polybed PSA technology is the result of years of technical innovation and commercial experience. As the industry leader in molecular sieve/adsorbent research and development, UOP combines superior high performance adsorbent technology with innovative process and mechanical design. Process benefits include:

  • The highest hydrogen recovery through the use of proprietary UOP adsorbents.
  • Maximum production of hydrogen due to control systems that automatically adjust to maintain production, even during upset conditions.
  • Lower capital cost due to adsorbent efficiency, process design, and control philosophy
  • Minimal feed pretreatment requirements
  • Long adsorbent life
