Over ten million tons! 2026 China ethylene plant maintenance plan

Thread Content

The planned major overhauls of ethylene plants in China in 2026 are mainly scheduled to take place in the second and fourth quarters. Geographically, the enterprises that will undergo these overhauls are located primarily in the East China and South China regions. North China and Northwest China are mainly home to coal chemical plants, while South China is primarily equipped with large-scale petrochemical plants ； In terms of corporate ownership, Sinopec’s facilities are relatively concentrated, while the facilities subject to planned maintenance by CNPC are mainly those of Guangdong Petrochemical. In terms of the number of maintenance companies, 2026 will not be a year of heavy maintenance activity, but operational load reduction is likely to become the norm. The routine maintenance plans for most enterprises in China for 2026 have been gradually finalized. Based on the information currently available and market trends, 2026 will not be a year of extensive maintenance activities for ethylene production facilities in China; planned maintenance is mainly scheduled to take place in the second and fourth quarters, with the majority of these facilities located in the East and South China regions. Since most ethylene cracking units are integrated facilities, their maintenance is typically carried out on a periodic basis. This mainly affects the supply and demand of downstream products, with limited impact on the ethylene market; therefore, attention is focused on the operational status of facilities such as Yangzi Petrochemical, Guli Petrochemical, and Shenghong Refining.
