DuPont Clean Technologies has been awarded the contract to supply Sinopec with a second Stratco alkylation unit; this time for the Sinopec Qilu Petrochemical Corporation (Sinopec Qilu).

Wilmington/USA — The Sinopec Qilu company is a large-scale refiner and producer of petrochemicals, fertilizers and chemical fiber in Zibo, Shandong Province. In order to comply with the China V standard of 10 ppm sulfur content for fuel, Sinopec commissioned the company for the license, engineering and equipment of a its alkylation unit with 400 kmta (10,300 bpsd) alkylate capacity.

According to the supplier, the alkylation unit will enable its client to generate low-sulfur, high-octane, low-Rvp alkylate with zero olefins that meets the criteria of the China V standard. Startup is targeted for mid-2018.

“Due to extreme plot space limitations within the Sinopec Qilu refinery, Dupont has designed the Stratco alkylation unit with the innovative Model 74 Contactor reactors. This is the first application of the Model 74 Contactor reactors, which were developed to reduce the number of reactors in an alkylation unit. This not only reduces the amount of plot space required, but also results in an overall lower capital cost while offering the extremely high reliability and on-stream time that refiners have come to expect from the Stratco alkylation technology,” said Kevin Bockwinkel, global business manager, Stratco Alkylation Technology.

Fundamentally, the Model 74 Contactor reactor is the same as commercially operating reactors of this type in service throughout the world.

Each reactor has a volume of 68.1 m3 while the standard size reactor (Model 63) has a volume of 43.5 m3 per reactor.

Efforts to Reduce Emissions in China

“Sinopec is driving gasoline and diesel production to new, lower-emission specifications at its refineries,” said Eli Ben-Shoshan, global business leader, DuPont Clean Technologies. “DuPont is pleased to be able to assist Sinopec with a custom-designed solution for its site to produce cleaner fuel.”

The Sinopec Tianjin Company (TPCC) had previously awarded a contract to the supplier for a alkylation unit at its oil refinery in the Tianjin Binhai New Area district in northern China. The Tianjin alkylation unit startup is scheduled for mid-2018.
