COLUMBIA, Md. — W. R. Grace & Co., a supplier of polyolefin catalyst technology and polypropylene (PP) process technology, contracted to license its UNIPOL PP process technology to Hengli Petrochemical Refinery Co. Ltd., a subsidiary of Hengli Group. The installation will be made at the company’s facility in Dalian, Liaoning province, China, and is expected to begin operations in 2019 using Grace’s leading SHAC Ziegler Natta PP catalysts.

Hengli Petrochemical’s PP unit is part of its new refinery complex designed to process 20 MMt of crude oil annually. The facility will produce a total of 450 kilotons per year of homopolymer, random copolymer, and impact copolymer thermoplastic resins in dual reactor lines. The project is one of 22 UNIPOL PP process technology reactor line licenses in China.

Grace’s UNIPOL PP process technology is an all gas-phase technology with the industry’s broadest product capabilities coupled with stable and predictable operation.

“Grace’s UNIPOL PP process and SHAC catalyst system offers us the most advanced PP product capacity available, and provides the most cost-effective technology to rapidly develop our portfolio of products,” Hengli Corporation’s Vice Chairman Chen Xinhua said.
