Honeywell UOP gets a Chinese petrochem project

Honeywell UOP announced that Zhejiang Petrochemical Co. Ltd. (ZPC) 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. The complex will use Honeywell Experion™ distributed control systems from Honeywell Process Solutions, and the PSA units will be controlled by Honeywell C300 controllers integrated with the Experion system.

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. Also, 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.
