DuPont Clean Technologies (DuPont) has been awarded the contract to supply Hengyi Industries SDN BHD (Hengyi) with licensing and engineering for a STRATCO® alkylation unit at the Brunei refinery in Pulau Murara Besar, Brunei. The new refinery will not only supply the domestic market but also plans to produce refined fuel for export. To comply with the China VI standard of 10 ppm sulfur content for fuel, Hengyi commissioned DuPont for a STRATCO® alkylation unit with 800 kmta (20,750 bpsd) alkylate capacity. The Pulau Muara Besar refinery and the petrochemical plant can refine 8 million tons of crude oil per year.
The STRATCO® alkylation unit will enable Hengyi to generate low-sulfur, high-octane, low-Rvp alkylate with zero olefins that meets the criteria of the China VI standard. The startup is targeted for 2023.
The STRATCO® alkylation Technology is sulfuric acid, a catalyzed process that converts low-value, straight-chain olefins (propylene, butylene, and amylene) into high-value, branched components called alkylate. Alkylate, with its superior blending properties, is a key component for clean gasoline and 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. The STRATCO® alkylation technology is licensed and marketed by DuPont as part of its Clean Technologies portfolio in Overland Park, Kansas. DuPont the alkylation technology company 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.
