China oil major PetroChina will shut its entire Yunnan petrochemical plant for maintenance from November 15, 2025, to January 15, 2026, the company said in a statement on Monday.

The overhaul covers about 23,000 tasks with a wide scope and significant depth, it said. Operational and supply adjustments will be made during the maintenance period.

The refinery in Southwestern China has a crude capacity of 13 million metric tons per year and mainly produces China VI–standard gasoline, diesel, and jet fuel, serving Southwestern China and Southeast Asia, according to a company report published in July.

Since its startup in 2017, it has processed 83 million tons of crude oil, and in 2024 alone, it processed 11.56 million tons of crude and produced 11.15 million tons of products, including gasoline, diesel, jet fuel, and LPG, the report said.

The timing of the two-month maintenance is based on unit operating conditions to ensure safe, reliable, and efficient operations after the overhaul, the company statement added.
