Core Content:This project serves as a benchmark for Sinopec's "reduce oil production, increase chemical output" strategy. While maintaining the annual crude oil processing capacity of 18 million tons unchanged, the project will drastically reduce refined oil output by 1.85 mt/a and increase ethylene feedstock production by 1.67 mt/a instead. Four key processing units will be newly built, including a 3 mt/a Deep Catalytic Cracking (DCC) unit. The annual ethylene production capacity will be expanded from the original 1 million tons to 1.64 million tons.
For downstream industries, priority will be given to constructing new production facilities including a 300kt/a propylene oxide unit, a 240kt/a hydrogen peroxide unit, and a 100kt/a POE (polyolefin elastomer) unit, filling the domestic gap in high-end polyolefins.
2026 Progress:The project is in the critical stage of completion and commissioning. Full mechanical completion is expected by the end of 2026, with some units such as the propylene oxide plant having already taken the lead in trial operation.
