2500N/M³ Gas Reformation PSA Hydrogen Plant Pressure Swing Adsorption Technology
Yulin Dongyuan Gas Reformation 2500N/M³ PSA Hydrogen Plant
Technology Application:
Hydrogen-rich gas is separated and purified for high purity hydrogen and proton
membrane fuel cell hydrogen standards(ISO 14687) through double high pressure swing adsorption technology(THiPSATM).
Pressure Swing Adsorption (PSA) - Hydrogen plant
Recovering and purifying hydrogen with PSA
Pressure Swing Adsorption (PSA) from TECHAIRS is used to recover and purify hydrogen from a variety of hydrogen-rich streams such as synthesis gases resulting from steam reforming and gasification processes or off-gases from refinery and petrochemical plants. The technology relies on differences in the adsorption properties of gases to separate them under pressure, and is an effective way of producing pure hydrogen.
We deliver PSA hydrogen plant 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.
Processes description
The feed gas for PSA generation plant can be raw hydrogen from a wide variety of sources, including steam methane reforming, partial oxidation, cryogenic purification, methanol plant purge gases, ethylene offgas, styrene offgas, gasification and ammonia plants.
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.
TECHAIRS PSA hydrogen plants uses the advanced adsorbents and control program design that are optimized for recovery and productivity rates. The PSA hydrogen plants are made for outdoor and unmanned operation, and are designed to be both compact and fully skid-mounted.
