Project Name: Integrated Refining and Chemical Processing Project of Sinopec Tahe Refining and Chemical Co., Ltd.
Nature of Construction: Expansion and renovation
Location of Construction: Chemical industry cluster area in Kuqa Economic and Technological Development Zone, Aksu Region, Xinjiang
Contents and Scale of Construction: Expand the existing refining capacity at Tahe Refining and Chemical from 5 million tons per year to 8.5 million tons per year, and build new production facilities for 800,000 tons per year of ethylene and 800,000 tons per year of aromatics. In the old refinery area, it is planned to build a No. 3 vacuum distillation unit with a capacity of 5 million tons per year, a No. 3 delayed coking unit with a capacity of 2.2 million tons per year, a hydrocracking unit with a capacity of 2.4 million tons per year, a PSA unit with a capacity of 100,000 standard cubic meters per hour, a No. 4 sulfur recovery unit with two units, each having a capacity of 60,000 tons per year, a No. 2 jet fuel hydrogenation unit with a capacity of 1 million tons per year, two fluidized bed residue hydrogenation units, each with a capacity of 2 million tons per year, and a No. 1 hydrogen production unit with a capacity of 80,000 standard cubic meters per hour. In the new chemical plant area, it is planned to build an ethylene plant with a capacity of 800,000 tons per year, a pyrolysis gasoline hydrogenation plant with a capacity of 450,000 tons per year, a butadiene extraction plant with a capacity of 100,000 tons per year, MTBE/butene-1 plants with capacities of 100,000/30,000 tons per year respectively, Plant #1 for polyethylene production with a capacity of 400,000 tons per year, Plant #2 for polyethylene production with a capacity of 400,000 tons per year, a polypropylene plant with a capacity of 400,000 tons per year, an aromatic compounds complex plant with a capacity of 800,000 tons per year, and Plant #2 for continuous reforming with a capacity of 1.5 million tons per year. As well as the utility systems, auxiliary facilities, storage and transportation facilities, environmental protection facilities, and off-site projects that are upgraded or newly constructed concurrently. Annual operating hours: 8,400 hours for the refining unit, continuous reforming and aromatics complex, and 8,000 hours for the chemical processing unit. Owner of the facility: Sinopec Tahe Refining & Chemical Co., Ltd. Estimated date of commissioning: The refining and aromatics complex is expected to be put into operation in June 2028, while the ethylene plant will commence operations in October 2029. Sinopec Tahe Refining & Chemical Co., Ltd. is located in Kuqa City, Aksu Region, Xinjiang; it is Sinopec’s only refining and chemical enterprise in that region. The company was established through a joint investment by Sinopec Corporation and Kuqa Asset Management Co., Ltd. At present, Tahe Refining & Chemical Company operates 16 production units, including atmospheric and vacuum distillation, delayed coking, hydrogen production from natural gas, hydroprocessing of gasoline and diesel, continuous reforming and hydroisomerization, as well as hydroprocessing of aviation fuel. The processing capacity is 5 million tons per year at atmospheric pressure and 500,000 tons per year under reduced pressure. It processes high-sulfur Tahe heavy crude oil, and can produce products such as gasoline, diesel, petroleum asphalt, mixed xylene/reformed oil, liquefied petroleum gas, petroleum coke, and sulfur.
