For continuous generation of hydrogen multiple adsorption towers are provided and are operated with auto change-over valves controlled by a PLC. After saturation of one tower with carbon dioxide the process automatically changes over to the next tower and thus the hydrogen production is continuous.
During the PSA process, the hydrogen is recovered and purified at a pressure close to the feed pressure, while adsorbed impurities are removed by lowering the pressure. The PSA tail-gas, which contains the impurities, can then be sent back to the fuel system even without a tail-gas compressor. The entire process is automatic.
HAVAYAR in participate with Global H2 PSA packagers use the most advanced adsorbents on the market with patented cycles that are optimized for recovery and productivity rates.
The units are made for outdoor and unmanned operation, and are designed to be both compact and fully skid-mounted.
We focus on plants for the production of hydrogen and synthesis gas, oxygen and olefins as well as plants for natural gas treatment.
