Gas purification

Through our Pressure Swing Adsorption (PSA) technology, we can ensure a high-purity gas stream with the desired quality.

PSA technology

Our gas purification technology utilizes Pressure Swing Adsorption (PSA) technology to deliver high-purity hydrogen. Our 4-vessel PSA system ensures continuous gas production through a cycle of adsorption and regeneration. Developed as a component of our Hy.GEN® systems, the Hy.PURE® technology delivers hydrogen purity levels up to 99.999% (5.0 quality) – essential for fuel cells and industrial processes.

High up-time

The Hy.PURE® has an uptime exceeding 99% and only needs semi-annual maintenance. The system operates for 15+ years without replacing the adsorbent material. Our control software manages pressure, volume, and cycle timing to deliver consistent performance. The Hy.PURE® is best-suited for customers who have a hydrogen gas stream that needs purification, with containerized solutions (20ft or 40ft) for site integration.

Optimizing hydrogen with PSA technology

The Hy.PURE® system operates at 6-14 bar(g) pressure. Above 11 feed pressure an additional compressor is necessary. The output pressure range can not be higher dan the feed pressure. When gas enters the vessels, impurities like nitrogen, carbon monoxide, carbon dioxide, water, chlorine, and methane stick to activated carbon while hydrogen flows through. Our VPSA (Vacuum Pressure Swing Adsorption) method uses vacuum pumps to improve the regeneration cycle. With one vessel purifying while three undergo regeneration through vacuum, blow-down, and equalization steps, the Hy.PURE® delivers a continuous stream of pure hydrogen.
