Guangxi Petrochemical revamps hydrogen unit with Honeywell UOP technology
DES PLAINES, Ill. — Honeywell announced that CNPC Guangxi Petrochemical Company has successfully converted its existing pressure swing adsorption (PSA) unit to Honeywell UOP Polybed PSA technology, enabling it to produce high-purity hydrogen.
The newly upgraded unit, located in Qinzhou in China's Guangxi Province, now supplies hydrogen at 99.9% purity and with increased hydrogen recovery for Guangxi Petrochemical's hydrotreating units, which use the hydrogen to extract impurities from the feedstock.
The Honeywell UOP Polybed PSA technology addresses several issues faced by many manufacturers in China, such as low recovery rates and purity, control valve leakage and poor or inconsistent performance.
The PSA process uses proprietary UOP adsorbents to remove impurities at high pressure from hydrogen-containing process streams, allowing hydrogen to be recovered and upgraded to more than 99.9% purity to meet refining needs. In addition to recovering and purifying hydrogen from steam reformers and refinery off-gases, the Polybed PSA system can be used to produce hydrogen from other sources such as ethylene off-gas, methanol off-gas and partial-oxidation synthesis gas.
