Nanjing Chengzhi shutdown takes China's coastal MTO operating rate to zero

All coastal China MTO plants relying on imported methanol have shut for the first time, with operating rates dropping to zero amid heavy losses and constrained Iranian supply. The shutdown has sharply cut methanol demand, though impacts on polyolefins remain contained.

Nanjing Chengzhi Clean Energy (Phase I)'s methanol-to-olefins (MTO) unit halted production on October 19, leaving all of China's coastal externally-sourced MTO plants offline for the first time. This rare blanket shutdown represented "economic elimination", driven by steep operating losses and disrupted Iranian methanol supply. China Coastal Externally-sourced MTO Unit Maintenance,
