Total investment 30 billion, including 800000 tons/year ethylene, 800000 tons/year PE, 400000 tons/year PP, Sinopec Tahe refining and chemical integration project approved.

on June 20, the Environmental Impact Assessment and Emission Management Office of the Department of Ecology and Environment of Xinjiang Uygur Autonomous Region made a decision to approve the environmental impact report (table) of the refining and chemical integration project of Sinopec Tahe Refining and Chemical Co., Ltd., and the publicity period is June 2025 From 20th to June 26th, 2025, a total of 5 working days. This approval indicates that the project has made important progress in the preliminary preparation stage and laid the foundation for the follow-up construction.

(I) Project Name and Nature

the name of the project is the refining and chemical integration project of Sinopec Tahe Refining and Chemical Co., Ltd., and the construction nature is reconstruction and expansion. The purpose of this reconstruction and expansion is to enhance the production scale and product diversification of the enterprise to meet market demand and enterprise development strategy.

(II) construction site

the project is located in the chemical industry concentration zone of Kuqa Economic and Technological Development Zone in Aksu Prefecture, Xinjiang. The region has a good industrial foundation and supporting facilities, which is conducive to the construction and operation of the project, and can also promote the development of enterprises with the help of local resource advantages and policy support.

(III) project investment

the total investment of the project is 29.987 billion billion yuan. Such a large-scale investment reflects Sinopec's attention and confidence in the project, and also reflects the higher requirements of the project in terms of technology, equipment and construction.

(IV) construction unit

the construction unit is Sinopec Tahe Refining & Chemical Co., Ltd. The company is located in Xinjiang National Kuqa Economic and Technological Development Zone, and is the only refining and chemical enterprise of Sinopec in Northwest China. In 2012, Sinopec actively responded to the spirit of the Central Xinjiang Work Conference, promoted industrial assistance to Xinjiang, and jointly established Tahe Refining and Chemical Company with Aksu. At present, Tahe Refining and Chemical has a crude oil processing capacity of 5 million tons/year and has 18 sets of production units, mainly processing Tahe crude oil. The products cover gasoline, diesel, aviation kerosene, asphalt, petroleum coke, sulfur, xylene, etc., and are sold directly to various places through the company's special railway line.

(I) oil refining unit expansion

on the basis of Tahe Refining's existing refining and processing capacity of 5 million tons/year, it will be expanded to 8.5 million tons/year. A series of units are proposed in the old refinery area, including 3 #5 million tons/year atmospheric and vacuum distillation unit, which is the initial link of oil refining process and carries out preliminary separation of crude oil; 3 #2.2 million tons/year delayed coking unit, used to treat heavy oil and produce light oil and petroleum coke; 2.4 million tons/year hydrocracking unit, which can improve oil quality and light oil yield; 100000 standard/hour PSA unit, used to produce high purity hydrogen; 4#2 × 60000 tons/year sulfur recovery unit to reduce sulfide emission and realize environmental protection production; 2#1 million tons/year aviation kerosene hydrogenation unit to improve the quality of aviation kerosene; 2 × 2 million tons/year boiling bed residue hydrogenation unit to further treat residue and improve resource utilization rate; 1 #80000 standard/hour hydrogen production unit provides necessary hydrogen for oil refining and chemical production.

New (II) chemical plant

A 800000-ton/year ethylene plant is planned to be built in the new chemical plant. Ethylene is an important basic raw material for the chemical industry, with many downstream products and broad market prospects. The 450000-ton/year pyrolysis gasoline hydrogenation unit hydrotreats pyrolysis gasoline to improve product quality; The 100000-ton/year butadiene extraction unit extracts butadiene from pyrolysis gasoline for the production of synthetic rubber, etc; 10/30000 tons/year MTBE/butene-1 plant, producing MTBE (methyl tert-butyl ether) and butene-1, MTBE can be used as gasoline additive, butene-1 is used in the synthesis of various chemical products; 1 #400000 tons polyethylene plant per year and 2 #400000 tons/year polyethylene plant produce polyethylene products, which are widely used in plastic products and other fields. 400000 tons/year polypropylene plant, which produces polypropylene, has a wide market demand; 800000 tons/year aromatics combined plant, which produces aromatic products, is an important chemical raw material; 2 #1.5 million tons/year continuous reforming unit, reforming naphtha, production of high octane gasoline components and aromatics.

(III) supporting works

at the same time, the project will also support the renovation or new public works, auxiliary facilities, storage and transportation projects, environmental protection facilities, off-plant projects, etc., to ensure the normal operation of the project and environmental protection standards.

(I) year running time

the annual operation time of the refining part, continuous reforming and aromatics combined unit is 8400 hours, and the annual operation time of the chemical part is 8000 hours. Different operating schedules are determined according to the production characteristics of each device and market demand, which helps to improve production efficiency and equipment utilization.

(II) and commissioning plan

it is expected that the refinery and aromatics complex will be put into operation in June 2028, and the ethylene plant will be put into operation in October 2029. This production plan fully considers the construction progress of the project, equipment installation and commissioning and other factors to ensure that the project can be successfully put into production and achieve the expected benefits.
