Fujian Refining and Petrochemical Co. Ltd. (FREP) has commissioned a new alkylation unit at its 12-million tonnes/year (tpy) integrated refining and chemical production complex at the southern coast of Meizhou Bay in Quanzhou, Fujian Province, China.
As of mid-December, FREP had started up and completed performance the performance test of the new STRATCO alkylation unit, certifying that the unit is meeting performance guarantees, technology licensor E.I. DuPont de Nemours & Co.’s DuPont Clean Technologies said in a release.
The STRATCO alkylation unit will process a mixed-butylene FCC feedstock into 7,700-b/sd (300,000-tpy) of low-sulfur, high-octane, low-rvp alkylate, enabling the complex to ensure its fuel production complies with the current China VI-A (equivalent to Euro 6) emission standard, which limits sulfur content in gasoline to a maximum of 10 ppm to help reduce automobile-generated pollution, according to the service provider.
Alkylate production from the unit also will comply with the pending China VI-B standard that—scheduled to take full effect in 2023—will further reduce levels of benzene, aromatics, and olefins in the gasoline pool, DuPont said.
Alongside Fujian Petrochemical Co. Limited (50%)—a joint venture of Sinopec and the Fujian government—FREP’s other shareholders include ExxonMobil China Petroleum & Petrochemical Co. Ltd. (25%) and Saudi Aramco Asia Co. Ltd. (25%).
