China: Hydrogen Production Largest Petrochemical Project in China to Use Honeywell's PSA Units
Honeywell UOP announced that Zhejiang Petrochemical will use four of its Polybed pressure swing adsorption (PSA) units to supply high-purity hydrogen for its new integrated refining and petrochemical complex in Zhoushan, Zhejiang Province.
Des Plaines/USA — The complex will use the manufacturer's Experion distributed control systems; the PSA units will be controlled by C300 controllers integrated with this system.
Zhejiang Petrochemical earlier awarded petrochemical process technology licensing, engineering design and catalysts to the company. When completed, the new plant will be the largest crude-to-chemicals complex in China and one of the largest in the world, manufacturing petrochemicals to make plastic resins, films and fibers, as well as fuels.
“Our customers in China are selecting UOP’s PSA technology as an extremely competitive and reliable source of high purity hydrogen,” said John Gugel, vice president and general manager, Gas Processing and Hydrogen at Honeywell UOP. “This is critical because hydrogen is essential to the operation of any refinery or petrochemical plant, and the quality of that hydrogen helps determine the efficiency of the entire complex.”
Polybed PSA systems are skid-mounted, modular units complete with hardware, adsorbents, control systems and embedded process technology, enabling quick and efficient installation to reduce cost and downtime.
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, the manufacturer claims. 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.
