Honeywell wins petrochemical project contract

Zhejiang Petrochemical Co. Ltd (ZPC) has contracted Honeywell UOP to supply four Polybed™ pressure swing adsorption (PSA) units for its new integrated refining and petrochemical complex in Zhoushan, Zhejiang Province, China.

The PSA units will supply high purity hydrogen for the complex, which will use Honeywell Experion™ distributed control systems from Honeywell Process Solutions. The PSA units will be controlled by Honeywell C300 controllers integrated with the Experion system.

Zhejiang Petrochemical earlier awarded petrochemical process technology licensing, engineering design and catalysts to Honeywell UOP.

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 fibres, as well as fuels.

John Gugel, Vice President and General Manager, Gas Processing and Hydrogen at Honeywell UOP, said: “Our customers in China are selecting UOP’s PSA technology as an extremely competitive and reliable source of high purity hydrogen […] 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. 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.
