DuPont Clean Technologies has announced that Hengli Petrochemical Company (Hengli), based in Dalian, China, has awarded the company 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% 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 utilise 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.
