Dushanzi Petrochemical Tarim Phase II Ethylene Project is accelerating

Petrochemical Industry Going Global Alliance | November 9, 2024

At present, Dushanzi Petrochemical is accelerating the construction of the Tarim 1.2 million tons/year Phase II ethylene project, which will quickly release 1.2 million tons of polyethylene, 450,000 tons of polypropylene, and 100,000 tons of rubber production capacity. At the same time, it can provide 400,000 tons of raw materials per year to drive the development of the downstream industrial chain.

The Tarim 1.2 million tons/year Phase II ethylene project adheres to the innovative and green construction concept and has built 11 major production units, 10 of which use domestic technology (9 use China Petroleum’s own technology); it maximizes the use of domestic technology and localized equipment, with a localization rate of 99%.

At the end of October this year, the first domestically produced dual-end functionalized solution-polymerized styrene-butadiene rubber SSBR3540 F was successfully started up at the 240,000 tons/year SSBR/SBS rubber unit of PetroChina Dushanzi Petrochemical, filling the domestic gap. Currently, the production capacity of solution-polymerized styrene-butadiene rubber of Dushanzi Petrochemical has reached 160,000 tons/year.

On September 17, the first large tower hoisting ceremony of the Tarim 1.2 million tons/year Phase II Ethylene Project of Dushanzi Petrochemical Company was held at the Shangku Petrochemical Park in Korla, Xinjiang.

As the first large tower, the quench water tower is the equipment with the largest diameter in the ethylene unit. It took only more than 100 days to complete the manufacturing, setting a record for the manufacturing of large oversized equipment. The main line of this hoisting used a 4,000-ton crane, and it took only 9 days to transport and assemble.

This hoisting marked the entry of the ethylene unit into the equipment installation stage, which kicked off the on-site construction.

The installation of the quenching water tower is the first large tower crane installation of the project, which opens the prelude to the installation of 9 large tower cranes in the entire ethylene unit. It is planned to complete the installation of 9 large tower cranes on October 31, marking a new stage in the construction of the ethylene unit project.

The main function of the cracking gas quenching water tower is to reduce the temperature of the cracking gas and recover low-grade heat at the same time. The cracking gas quenching water tower achieves cooling and partial condensation of the cracking gas through direct countercurrent contact with the quenching water. This process not only helps to reduce the temperature of the cracking gas and separate part of the gasoline in the cracking gas, but also recovers part of the low-grade heat through the quenching water cycle, further improving energy utilization efficiency. This series of operations effectively reduces the temperature of the cracking gas, ensures the normal operation of the cracking gas compressor, greatly reduces the amount of sewage discharged, and improves the energy utilization efficiency of the ethylene unit and reduces energy consumption by recovering low-grade heat.

At present, the overall progress of the project has been completed by 13.6%. It is planned to complete the construction of the underground pipeline network of the entire site on September 20 and the construction of the entire road on October 30. This year's interim goal is to complete 70% of the soil-less construction before the arrival of winter, creating good conditions for installation next year.

The total investment of the Dushanzi Petrochemical Tarim 1.2 million tons/year Phase II ethylene project is 21.88 billion yuan. After completion, it can produce more than 2 million tons of high-end polyolefins and high-performance rubber materials annually, further improving the localization rate of the domestic high-end petrochemical product industry chain supply chain. The basic machinery of the project is scheduled to be completed by the end of 2025, and fully completed and put into production in 2026.

On the morning of November 28, 2023, the construction of the 120,000 tons/year solution butadiene styrene rubber (SSBR) unit and the 80,000 tons/year styrene-butadiene-styrene thermoplastic elastomer (SBS) unit of the Guangxi Petrochemical Refining and Chemical Integration Transformation and Upgrading Project started.

Among them, the 120,000 tons/year solution-polymerized styrene-butadiene rubber (SSBR) unit adopts a complete set of technologies jointly developed by China Petroleum and Chemical Research Institute and Lanzhou Huanqiu Engineering Co., Ltd. The unit has two production lines, a 60,000 tons/year continuous polymerization SSBR production line and a 60,000 tons/year intermittent polymerization SSBR production line, which can produce the largest general-purpose grades and fourth-generation functionalized grades in the domestic market. The grades of the intermittent production line are mainly third/fourth-generation functionalized grades, and the grades can be customized and developed according to the needs of the downstream market. The unit is EPC-contracted by a consortium consisting of Lanzhou Huanqiu and CNPC Seventh Construction, and is scheduled to be delivered in June 2025.

80,000 tons/year styrene-butadiene-styrene thermoplastic elastomer (SBS) plantThe process technology jointly developed by Xinjiang Huanqiu Company and Dushanzi Petrochemical is adopted. The key technology of this process lies in its SBS intermittent polymerization technology, which has great production flexibility and can produce a variety of grades of products. According to the final use and product range, SBS products with different components and structures can be produced to meet the needs of downstream asphalt modification, polymer modification, shoemaking, adhesives, etc. The consortium composed of Xinjiang Huanqiu and CNPC First Construction will undertake the EPC general contracting, and the project is scheduled to be handed over in June 2025.

Entering November, the Guangxi Petrochemical Refining and Chemical Integration Transformation and Upgrading Project has been successful, and many installation tasks have been completed according to the nodes. At present, the overall progress of the project has been completed by 62.81%, and the construction progress has exceeded half.

In order to improve the project construction progress and ensure the quality and inherent safety of the project, the Guangxi Petrochemical Refining and Chemical Integration Transformation and Upgrading Project strictly implemented the group company's "six-in-one" construction concept at the beginning of the design, and made the construction safer, more efficient and reliable through factory prefabrication and modular construction. In order to further promote factory prefabrication and modular construction, Guangxi Petrochemical has built "second construction sites" of varying sizes near the project construction site in accordance with local conditions - prefabrication yards, of which there are 8 pipeline prefabrication yards alone. The factory prefabrication rate of the steel structure of this project exceeds 95%, and with the concept of deepening factory prefabrication and modular construction, the operating efficiency has been greatly improved, the workload and safety risks on the construction site have been greatly reduced, and civilized construction on site has been further promoted.

7 Nov 2024

PetroChina, one of China’s major oil companies, plans to close its Dalian refinery in northeastern China by mid-2025, marking the first complete shutdown of a state-operated refinery in the country. The Dalian refinery, which dates back to 1993, has a crude processing capacity of 410,000 barrels per day (bpd) and a Nelson complexity index of approximately 6.1, reflecting its ability to handle various crude oil types and produce a range of refined products. It contributes around 3% of China’s total refining capacity and has been a significant part of PetroChina’s refinery network for decades.

The refinery plays a vital role in supplying refined products to the Chinese domestic market, including diesel, gasoline, and jet fuel. While its primary focus has been on meeting local demand, the Dalian refinery has also engaged in exports, supplying refined products to other regions in Asia, particularly  Japan and  South Korea. The facility primarily processes  Russian ESPO (East Siberia Pacific Ocean) crude, which is delivered via pipelines from Siberian fields through China’s northeastern region.

PetroChina’s decision to close the Dalian refinery stems from multiple factors, including overcapacity, weakened domestic fuel demand due to slower economic growth, and an increase in vehicle electrification across China. Environmental concerns have also played a role, as the refinery has been situated in a densely populated area, with incidents such as an oil spill in 2010 and fires in 2013 and 2017 highlighting the risks of operating a large facility in close proximity to urban areas.

The phased shutdown began in October 2023, with PetroChina closing a 210,000-bpd unit within the refinery. The remaining capacity is scheduled to be taken offline by 2025. Once the shutdown is complete, PetroChina intends to redirect crude oil supply to other refineries in northern China, including the WEPEC (West Pacific Petrochemical Company) refinery in Dalian and another facility in nearby Jinzhou.

In a bid to offset the reduction in refining capacity, PetroChina’s parent company, the China National Petroleum Corporation (CNPC), announced plans to develop a new, smaller refinery and chemical complex on Changxing Island, approximately two hours from Dalian. This project, valued at CNY70 billion (USD 9.6 billion), is expected to process around 200,000 bpd of crude oil and produce 1.2 million tonnes of ethylene annually. However, the new complex is still in the pre-feasibility stage, and a final investment decision has yet to be made.

The closure of the Dalian refinery underscores PetroChina’s efforts to modernise its infrastructure, reduce environmental risks, and adapt to changing energy demands. With China moving towards greener energy solutions and reduced reliance on fossil fuels, PetroChina’s shift reflects the country’s broader strategic push towards sustainability.
