Hengli Petrochemical selects Dupont technologies for alkylation complex
DuPont Clean Technologies announced that Hengli Petrochemical Company, based in Dalian, China, has awarded DuPont a contract to supply the alkylation and spent acid regeneration technologies for the nrew, grassroots refinery in the Changxing Island Harbor Industrial Zone.
The contract includes the license and engineering design packages for the Stratco alkylation an Mecs SAR units. Instillation of the new units at Hengli is planned for 2018, with startup anticipated in 2019.
“DuPont is pleased to provide Hengli Petrochemical with our world-class sulfuric acid alkylation technology to improve 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.”
The alkylation process was invented in the 1930’s and since that time, alkylation feed streams have primarily come from either the FCC, MTBE or Coker. Typical alkylation feeds are made up of Butylene olefins, and in some cases propylene and/or amylene olefins as well.
DuPont is developing numerous projects with atypical olefin feed streams, such as 100% isobutylene, 100% propylene and 100% amylene. Driven by the low cost of LPG and the high value of alkylate, many in the refining and petrochemicals industries are finding that converting these atypical feed streams into alkylate make for very attractive projects.
DuPont’s Stratco sulfuric acid alkylation technology is being used by customers with the most unusual and challenging feedstocks when a full-range of olefins may not be an option.
