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.

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.
