Hydrogen Recovery and Purification

Our proven high-performance pressure swing adsorption (PSA) plants can be used to recover and purify hydrogen from hydrogen-rich streams such as synthesis gases resulting from steam reforming and gasification processes or off-gases from refinery and petrochemical plants.

We support the full spectrum of capacities from small plants producing a few hundred Nm³/h to large-scale plants that produce more than 400,000 Nm³/h. Our proven technology delivers the highest recovery rates, and the resulting hydrogen gas meets all purity requirements up to 99.9999 mol-%.

We deliver PSA solutions to a variety of customers in the electronics, biomass and steel industries. More importantly, we also supply refineries, which require large volumes for hydrocracking, dearomatisation and desulphurisation processes. In addition, we support petrochemical plants, which need high volumes of hydrogen for processes such as methanol and ammonia synthesis.

Our high performance PSA plants deliver a host of benefits, including:

• The perfect balance between plant performance and investment costs.
• Outstanding quality and reliability thanks to rigorous selection, testing and approval of plant components.
• Virtually 100% on-stream performance and availability due to special features such as reduced number of adsorbers, adsorber group isolation and redundant control systems.
• Tailor-made solutions for individual feed gas conditions and hydrogen demands.
• Reduced costs and faster on-site set-up and commissioning times due to modular design and prefabricated equipment.
• Easy maintenance
