Pressure Swing Adsorption (PSA) has revolutionized the production of purified hydrogen worldwide with several thousand total plants constructed. Decades of competing investment have yielded a huge number of technical advances, making the engineering of PSA plants fundamentally an “open book” process like steam reforming, but extremely complex to do correctly, and highly dependent on the technical skill of the supplier.

Howe Baker’s  PSA plants utilize the fewest adsorber beds and lowest number of switching valves in the industry for equivalent capacity and performance, and have demonstrated run times up to five years between valve overhauls. This innately low complexity assures greater reliability and less costly operations and maintenance, critical technological advantages for smaller plants: 10 MMscf/day and below. Having completed H2 PSA plants around the world with capacities up to 50 tonne/day in challenging applications with high purity up to 99.9999% our hydrogen recovery matches the optimum worldwide benchmarks, i.e. up to 87% in steam reforming applications.

We fundamentally believe that any customer interested in a H2 PSA plant demand:

Switching valves from internationally-recognized manufacturers proven to deliver 5 years between turnaround

• Ability to operate with one adsorber vessel offline for maintenance
• Load following and product purity control
• Complete Finite Element Analysis (FEA) of adsorber vessels
• The most advanced adsorbents, which deliver higher purity and lower overall system cost
