DuPont to supply clean technologies for Hengli’s new Chinese refinery
Dalian, China-based Hengli Petrochemical Co. has awarded a contract to DuPont Clean Technologies 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 at DuPont. “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 utilize the patented XP2 technology in the STRATCO Contactorreactor. 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 says it is the world leader in alkylation technology with over 90 units licensed and with more than 800,000 bpd of installed capacity.
DuPont says it is committed to alkylation research and has extensive experience in assisting refiners with alkylation research, design, start-ups, test runs, troubleshooting, optimization, revamps, expansions, analytical testing, operator training, turnarounds and HAZOP studies.
