PSA technology is widely used to purify hydrogen streams produced from reforming, refining, or renewable hydrogen generation processes. These systems remove impurities such as CO₂, methane, and nitrogen to produce high-purity hydrogen suitable for industrial or energy applications.
PSA nitrogen systems separate nitrogen from compressed air to produce high-purity nitrogen used in industries such as food processing, electronics manufacturing, chemical processing, and oil & gas operations.
PSA oxygen generators use zeolite adsorbents to separate oxygen from compressed air, producing oxygen streams suitable for industrial processes, medical applications, wastewater treatment, and metal processing.
PSA systems can be integrated with cryogenic processing technologies to purify helium streams recovered from natural gas production, supporting high-purity industrial helium markets.
PSA technology can be used to upgrade biogas or landfill gas by removing impurities such as CO₂, nitrogen, and moisture, producing renewable natural gas suitable for pipeline injection or energy applications.
PSA systems can also support CO₂ separation and recovery processes, helping operators capture valuable carbon streams while reducing emissions.
ARJAE designs PSA facilities using a modular fabrication approach, allowing systems to be assembled and tested prior to shipment to site.
