DuPont Clean Technologies (Overland Park, Kan. www.cleantechnologies.dupont.com) is pleased to announce that Hengli Petrochemical Co. (Hengli), based in Dalian, China, has awarded DuPont a contract to supply the alkylation and spent-acid regeneration (SAR) technologies for the new grassroots refinery in the Changxing Island Harbor Industrial Zone. The contract includes the license and engineering design packages for the Stratco alkylation and MECS SAR units. Installation of the new units at Hengli is currently planned for 2018 with startup anticipated in 2019.
The grassroots refinery complex, with the addition of Stratco alkylation technology, will allow Hengli to produce a high-quality alkylate product (used as a blending component in the gasoline pool) from a 100% isobutylene feed stream.
“DuPont is pleased to provide Hengli Petrochemical with our world-class sulfuric acid alkylation technology to improve the overall gasoline pool from the refinery,” said Kevin Bockwinkel, global business manager for the Stratco Alkylation Technology. “The unique feed stream (100-percent isobutylene) available from the Hengli Petrochemical facility marks the beginning of a new era for alkylation in the gasoline market as the butane-to-alkylate movement grows around the world.”
Stratco alkylation technology is licensed and marketed by DuPont as part of its Clean Technologies portfolio .
