Sinopec Launches Seventh Alkylation Unit

DuPont Clean Technologies announced that the Stratco alkylation unit at the Fujian Refining and Petrochemical Co., Ltd refinery in Quanzhou has successfully started up and completed the performance test, certifying that the unit is meeting performance guarantees.

“Over the last several years, we have been able to work with multiple Sinopec refineries, building an energetic relationship and providing a reliable technology solution at each site. The consistency of our technology provides Sinopec the ability to deliver high quality alkylate to the gasoline pool, decreasing the environmental impact of its fuels. It has been a pleasure to work regularly with the Sinopec organization, a rapport that will continue throughout the lives of these seven units,” said Kevin Bockwinkel, global business manager, STRATCO® Alkylation Technology.

With this startup at the FREP refinery, the total capacity of alkylate produced by Startco® alkylation units in the Sinopec refinery network is 60,380 bpsd (2,360 kmta).

The Stratco alkylation technology is a sulfuric acid-catalyzed process that converts low-value, light olefins (propylene, butylene and amylene) into high-value, branched components called alkylate. Alkylate is known for its superior blending properties and is a key component for clean gasoline. The STRATCO® alkylation technology helps refiners safely produce cleaner-burning gasoline with high octane, low Reid vapor pressure, low sulfur, zero aromatics and zero olefins. Licensed and marketed by DuPont as part of its Clean Technologies portfolio, the STRATCO® alkylation technology is the world-leading alkylation technology with more than 100 licensed units worldwide and more than 915,000 bpsd (35,800 kmta) of installed capacity. DuPont 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.
