Vonen - Model H2-PRF / MHS - Hydrogen Purification and Dehumidification Systems

The VONEN H2-PRF / MHS Hydrogen Purification and Dehumidification System Allows continuous purification, storage and use of hydrogen gas. The system is based on the use of the H2-MHS VONEN hydrogen storages’ metal hydride, which only absorbs hydrogen and rejects most contaminants like oxygen, water and nitrogen. These contaminants are purged out from the H2 storage vessel.

VONEN PSA - PSA Systems for Hydrogen Purification and Recovery

VONEN Pressure Swing Adsorption (PSA) product range for Hydrogen Recovery and Purification. With our PSA Systems, hydrogen can be recovered from various sources and purified further. Good examples include: - Upgrading industrial hydrogen-rich waste streams from Ammonia production: up to 180–240 Nm3 H2 per ton of NH3 is purged to keep the inert gases concentration below a threshold value. - Syngas, where we have exceptional competitive advantage regarding CO adsorption - See CO adsorption graph in https://vonen.com/psa-hydrogen-purification/ - Biogas production. - Chlor-alkali process. - Electrolysis of water: Drying / Dehumidification of hydrogen, including integration upstream with Gas-Water Separator and Catalytic Reactor as well as integration downstream with H2 Buffer Storage. The purified hydrogen can be guaranteed to comply with the quality standards set for fuel cell vehicles and electronics industries.
