Sinopec and DuPont sign contracts for alkylation units

DuPont Clean Technologies (DuPont) has signed 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 the grassroots alkylation units.

The awards include one of China’s leading suppliers of olefins and aromatics, Sinopec Yangzi Co. (YPC), as well as Sinopec Zhenhai Refining and Chemical Co. (ZRCC). In the months prior to these awards, DuPont was commissioned to supply its grassroots alkylation units for three other large-scale refining facilities at Sinopec Tianjin, Sinopec Qilu and Sinopec Zhongke.

Sinopec is looking to DuPont for help in complying with the strict gasoline emissions regulations introduced as part of the China V standards in January 2017. Its alkylation technology allows refiners to produce cleaner-burning fuel with high octane, extremely low sulfur content, low Rvp and zero olefins. The five alkylation units commissioned by Sinopec range in size from 300 kmta (7700 bpsd) to 400 kmta (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 over 90 units licensed worldwide and more than 850 000 bpsd (33 300 kmta) of installed capacity. The alkylation technology is a sulfuric acid catalysed process that converts olefins and low-value isobutane into high-value alkylate, a key desirable component for clean fuel. With units built over 80 years ago still in operation, the technology is a highly effective, reliable solution for producing cleaner-burning fuel with high octane, low Rvp, low sulfur and zero olefins.
