Sinopec’s Tianjin refinery due new alkylation unit

China Petrochemical Corp. (Sinopec) has let a contract to a division of E.I. DuPont de Nemours & Co. to provide process technology and engineering for a new alkylation unit to be built at subsidiary Tianjin Petroleum & Chemical Corp.'s (TPCC) 15.5-million tonne/year integrated refining and petrochemical complex at Tianjin Binhai New Area, Tianjin, in northern China.

As part of the contract, DuPont Clean Technologies, Overland Park, Kan., will deliver licensing and engineering design for its proprietary STRATCO sulfuric acid alkylation unit, the service provider said.

Alongside technology licensing and engineering, DuPont also will provide proprietary equipment, operator training, and commissioning assistance for the new unit, which will be designed to meet TPCC’s requirements for improving quality of the refinery’s existing gasoline pool to ensure compliance with China 5-quality standards for cleaner fuels.

Equivalent to Euro 5-quality fuel standards, China 5 emission standards cap the maximum sulfur content of gasoline and diesel at 10 ppm, according to China’s Ministry of Environmental Protection.

With project construction scheduled to begin in early 2017, TPCC currently is planning to commission the 7,700-b/sd STRATCO alkylation unit by late 2017 or early 2018, DuPont said.

A value of the contract was not disclosed.
