Innovations and Hydrogen Processing

Technical innovation in adsorbent and membrane chemistry, along with process design and control expertise make UOP the industry’s choice to manage your new installation – from initial development to commissioning and start-up.
Our hydrogen purification solutions provide targeted hydrogen recovery and high product purity levels. Hydrogen can be produced on purpose or can be a valuable by-product. Regardless of how it’s produced, it must be recovered and purified to be useful in downstream processing.

UOP has completed more than 200 successful revamps, which offer many benefits, including:
  • New Product Specifications
  • Change in Feed Composition
  • Increased H2 Product Recovery
  • Increased H2 Product Capacity
  • Upgraded Control System
  • Increased Reliability for older units

The industry standard for sustainable H2 purification and long-term, reliable recovery

 
With more than 1,000 systems installed in more than 70 countries, Polybed PSA technology is the result of years of technical innovation and commercial experience. And as the industry leader in molecular sieve/adsorbent research and development, UOP combines high-performance adsorbent technology with innovative process and mechanical design.

UOP’s PSA process benefits include:

  • 99.95% onstream reliability in supply of 99.999% purity hydrogen, providing enhanced performance and value for downstream units
  • Higher reliability of operations can lead to: more uptime, higher hydrogen recovery per year and more stable downstream operations
  • High hydrogen recovery through the use of proprietary UOP adsorbents
  • Enhanced reliability in 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 (>30 years)
  • Units designed to make them easy to revamp and stay current as technology improvements are made available over time.

Polybed PSA systems are offered as skid mounted, modular units, complete with hardware, adsorbents, and controls systems. We do the detailed design and project management, with fabrication completed by rigorously qualified sub-vendors under our supervision.

Let UOP manage your installation:

  • Superior knowledge of upstream and downstream hydrogen requirements and implications – we can help design the most economical unit in the most profitable application
  • Valves, vessels, and other equipment selected specifically for PSA service

Low-cost solutions for high-pressure hydrogen separations

 
Hydrogen membranes can be cost effective solutions for hydrogen recovery or separation applications when the feed stream is at high pressure (typically > 1000 psig) and a lower pressure product stream at 95+% purity fits process requirements.
Polysep Membrane Systems combine state-of-the-art composite membrane technology with advances in polymer science for a fundamentally different membrane. With both hollow fiber and spiral membrane elements, our separation polymers offer a range of permeability, selectivity, and contaminant resistance, and are used in more than 80 sites worldwide.

Produce high-purity hydrogen to help optimize catalytic processes performance

 
Steam reforming of light hydrocarbons like natural gas is the dominant technology for the production of syngas. The hydrogen produced by this process requires purification before it is used downstream. UOP’s Polybed PSA system produces the high-purity hydrogen needed for optimum performance of catalytic processes, and is a proven choice for purifying hydrogen to meet downstream process requirements.

We were the first to commercialize PSA technology for steam reformer service and have provided more than 400 PSA systems with hydrogen production capacities ranging from 1 to more than 244 MMSCFD (1,000 – 268,000 Nm3/hr).

Before the gas can be processed in the downstream methanation step, carbon dioxide must be removed to low levels to avoid catalyst degradation. The UOP Amine Guard™ FS process is designed to efficiently remove CO2 to the desired specification.
