MOSCOW (MRC) -- DuPont Clean Technologies (DuPont) announced the successful startup and performance test of a 300 KMTA STRATCO alkylation unit licensed by DuPont at the Hengli Petrochemical Company (Hengli) new refinery complex, Changxing Island Harbor Industrial Zone, China, reported Hydrocarbonprocessing.
The new alkylation unit enables Hengli to produce high-quality alkylate, a key component for cleaner, high octane gasoline, from a 100% isobutylene feed stream. This first-of-a-kind unit was developed through DuPont research into the best ways to maximize product octane and minimize end point with this feedstock. Hengli had awarded DuPont the contract for the new alkylation unit as well as a MECS Sulfuric Acid Regeneration unit in 2015.
The alkylation unit uses the latest innovative patented XP2 technology by DuPont in the STRATCO Contactor reactor. The reactor enhancement is designed to improve the acid/hydrocarbon emulsion flow path near the tube bundle heat transfer area of the reactor in order to realize significant process benefits and achieve optimal alkylate product quality.
“DuPont Clean Technologies could not be happier with its ability to enable Hengli Petrochemical Company to meet performance guarantees while processing a feed never before processed in an alkylation unit,” said Eli Ben-Shoshan, Global Business Leader, DuPont Clean Technologies. “It’s a groundbreaking achievement and we’re very pleased to provide innovative technology and services that support the operational and business goals of Hengli.”
“We’re delighted that the new alkylation unit is performing to design specifications,” said a unit manager at the Hengli Petrochemical Company. “The fact that we’re able to produce high-quality alkylate with high-octane values from isobutylene by using the STRATCO alkylation technology benefits our refinery’s overall gasoline pool.”
The STRATCO Alkylation Technology is a sulfuric acid, catalyzed process that converts low-value, straight-chain olefins 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 RVP, low sulfur, zero aromatics and zero olefins. STRATCO alkylation technology is licensed and marketed by DuPont as part of its Clean Technologies portfolio in Overland Park, Kansas. DuPont is the world leader in 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.

As MRC wrote oreviously, Hengli Petrochemical Co Ltd ramped up the operation rate of its new No. 5 purified terephthalic acid (PTA) line at Dalian to around 85% on 11-12 July, 2020. The company managed to produce prime grade PTA cargoes at its new PTA line in China on 30 June. This line was successfully launched on 28 June, 2020. Based in Dalian, China, the company has 5 PTA plants with combined production capacity of 11.6 million tons/year, making Hengli Group the world's largest PTA producer, as each PTA plant has production capacity of 2.5 million tons/year.
As per MRC's ScanPlast report, May estimated PET consumption in Russia amounted to 70,170 tonnes, which corresponds to the level of consumption last year (70,450 tonnes). In total for the period January - May of this year, the estimated PET consumption in the Russian Federation amounted to 304,310 tonnes of material. This is 3% lower than the same indicator in 2019.
