[Project Background] The Kazakhstan butadiene plant project is a crucial component in the development of the country's downstream petrochemical industry. Butadiene is a key monomer for producing important polymer materials such as synthetic rubber and ABS resin. Upon completion, the project will fill the production gap in this field in Kazakhstan.

[Role of Chinese Enterprises] In March 2026, Sinopec Engineering Group successfully won the EPC general contract for the Kazakhstan butadiene plant project. This marks another significant EPC contract secured by the company in the Kazakhstan market, following the Silleno ethane cracking project in September 2024.

[Scope of Services] L4 EPC general contracting, providing full-process services including engineering design, equipment procurement, and construction for the butadiene production plant.

[Typical Significance] Demonstrates Sinopec Engineering's continuous breakthroughs in the Kazakhstan market, forming a series of layouts in the Central Asian polymer materials sector and deepening China-Kazakhstan petrochemical cooperation.
