DuPont Clean Technologies (DuPont) is pleased to announce that Hengli Petrochemical Company (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 start-up 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.”

As part of DuPont’s commitment to innovation, the alkylation unit at Hengli will utilize the patented XP2 technology in the STRATCO® Contactor™ reactor. The XP2 technology is one of the latest Contactor™ reactor enhancements developed by DuPont to ensure the most effective and efficient use of the tube bundle heat transfer area, providing significant process benefits resulting in improved alkylate product quality.

STRATCO® alkylation technology is licensed and marketed by DuPont as part of its Clean Technologies portfolio in Overland Park, Kansas. DuPont is the world leader in alkylation technology with over 90 units licensed and with more than 800,000 BPSD (31,400 kmta) of installed capacity.
