DuPont to provide STRATCO alkylation technology license to Sinopec

DuPont Clean Technologies signs contracts with China Petroleum & Chemical Corporation (Sinopec) for five grassroots STRATCO alkylation units at five Sinopec refineries in China.

The scope of these contracts includes the license, engineering and supply of proprietary equipment for grassroots STRATCO alkylation units. The most recent awards include one of China’s leading suppliers of olefins and aromatics, Sinopec Yangzi Company (YPC), as well as Sinopec Zhenhai Refining and Chemical Company (ZRCC). DuPont was commissioned to supply grassroots STRATCO alkylation units for three other large-scale refining facilities at Sinopec Tianjin, Sinopec Qilu and Sinopec Zhongke in China.

Sinopec is looking to DuPont Clean Technologies for help in complying with the strict gasoline emissions regulations introduced as part of the China V standards in January 2017. The STRATCO alkylation technology enables refiners to produce cleaner-burning fuel with high octane, extremely low sulfur content, low Rvp and zero olefins. The five STRATCO alkylation units commissioned by Sinopec range in size from 7,700 bpsd to 10,300 bpsd alkylate production and will be built in Tianjin municipality and Shandong, Zhejiang, Jiangsu and Guangdong provinces. Startup for the first four alkylation units is expected by mid to late 2018.

STRATCO alkylation technology is the established global leader in the industry with more than 90 units licensed worldwide and more than 850,000 bpsd of installed capacity. The STRATCO alkylation technology is a sulfuric acid catalyzed process that converts olefins and low-value isobutane into high-value alkylate. This high-value alkylate is a key desirable component for clean fuel.
