ZPC will use four Honeywell UOP Polybed pressure swing adsorption (PSA) units to supply high-purity hydrogen for the second phase of an integrated refining and petrochemical complex.
Honeywell UOP announces that Zhejiang Petrochemical Co. Ltd. (ZPC) will use four Honeywell UOP Polybed pressure swing adsorption (PSA) units to supply high-purity hydrogen for the second phase of an integrated refining and petrochemical complex in Zhoushan, Zhejiang Province. The complex is one of several new large industrial sites that are part of China’s current national economic development plan.
Zhejiang Petrochemical earlier awarded petrochemical process technology licensing, engineering design and catalysts for the first two phases of the project to Honeywell UOP. When completed, the new plant will reportedly 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, and fuels.
“High-purity hydrogen is a critical element in the efficient operation of these complexes because all of the conversion technologies in them depend on it,” says Bryan Glover, vice president and general manager, petrochemicals and refining technologies at Honeywell UOP.
UOP announced the first phase of the ZPC project in 2017, including technologies for hydroprocessing and heavy oil upgrading, and production of aromatics for plastic resins, films and fibers. ZPC awarded the second phase of the project in January 2019, doubling the plant’s aromatics capacity to about 12 million metric tons per year. With more than 50% of its crude capacity converted to petrochemicals, it will move China closer to self-sufficiency in paraxylene production and be a major new source of propylene and other products, according to Honeywell.
