The debottlenecking revamp and energy efficiency upgrading project for Fushun Petrochemical’s 800 kt/a ethylene plant has entered its final construction phase. Handover for commissioning is scheduled for the end of June 2026, with formal commissioning and startup by late September. Upon completion, the plant’s annual ethylene capacity will rise from 800,000 tons to 950,000 tons, with a total investment of 2.58 billion yuan.
Alongside the ethylene capacity expansion from 800 kt/a to 950 kt/a, a brand-new 200 kt/a solution-process polyethylene plant will be constructed, adopting PetroChina’s first domestically developed proprietary process technology. Auxiliary supporting units including air separation, butadiene extraction and MTBE facilities will also undergo technical upgrading.
The project applies a modular "building-block" construction methodology. For instance, the No.9 cracking furnace was fully pre-assembled at a prefabrication yard before being shifted into place as a whole. This construction mode enables revamping works to proceed alongside ongoing plant production without disrupting the normal operation of existing facilities. In addition, domestically manufactured million-ton-class ethylene compressors and proprietary large-scale ethylene technologies developed by China Huanqiu Contracting & Engineering Corporation are deployed for the project.
