MOSCOW (MRC) -- DuPont Clean Technologies (DuPont) announced that the STRATCO alkylation unit at the Sinopec Qilu refinery in Zibo, Shandong Province, China, successfully completed the performance test, certifying that the unit is meeting required performance guarantees, said Hydrocarbonprocessing.
The STRATCO alkylation unit at Sinopec Qilu Petrochemical Corporation (Sinopec Qilu) is designed to produce 400 kmta (10,300 BPSD) of alkylate product from a MTBE raffinate feedstock and enables production of low-sulfur, high-octane, low-Rvp alkylate with zero olefins that meets the criteria of the China V standard.
"It is our great pleasure to see this successful collaboration between DuPont and Sinopec come to fruition. In order to meet extreme plot space limitations within the refinery complex, DuPont worked to design and fabricate the Model 74 Contactor™ reactor, reducing equipment count and providing high reliability to Sinopec. We are very pleased with the implementation of this larger reactor, affording Sinopec Qilu the high on-stream time they have come to expect from our technology. As Sinopec continues to drive towards lower emission specifications, DuPont was excited to assist with a custom-designed solution,” said Kevin Bockwinkel, global business manager, STRATCO® alkylation technology.
The Sinopec Qilu refinery marks the first commercialization of the innovative Model 74 Contactor reactors. Fundamentally the same as commercially operating reactors in service throughout the world, the Model 74 Contactor reactors reduce the total number of reactors and plot space required for STRATCO® alkylation units and result in an overall lower capital cost. These reactors continue to offer the high reliability and productivity refiners have grown accustomed to with the STRATCO® alkylation technology.
The Model 74 Contactor reactor includes the latest reactor improvements and each has a volume of 68.1 m3 (18,000 gallons), increasing volume from the standard size Contactor (Model 63) at 43.5 m3 (11,500 gallons) per reactor. Both reactor models are commercially available from DuPont.
The STRATC® alkylation technology is a sulfuric acid-catalyzed process that converts low-value, straight-chain 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.
It was erlier reported, DuPont is investing USD400 million in the production capacity of Tyvek nonwoven fabric made from high density polyethylene (HDPE) at its site in Luxembourg. A new building and a third work line at the production site will be constructed. The launch of new facilities is scheduled for 2021.
As per MRC ScanPlast, September HDPE imports were 18,600 tonnes, which corresponds to the figure a month earlier. Overall imports of this PE grade totalled 202,500 tonnes in January-September 2020, down by 27% year on year. The largest decrease in supplies was due to film and pipe HDPE.
DuPont Corporation, founded in the USA in 1802, operates in more than 70 countries. The company produces specialty chemicals, offers goods and services for agriculture, food production, electronics, communications, security and protection, construction, transport and light industry. In Russia, DuPont has 100% control over the DuPont Khimprom plant since 2005, and in 2006 established a joint venture between DuPont - Russian Paints and Russian Paints.
