April 18, 2025 | Paraffin Industry Innovation Fushun Petrochemical Company has achieved a 20% surge in liquid paraffin production capacity following a targeted maintenance initiative dubbed the "Cleaning Campaign.
Key operational data confirms post-maintenance feed rates now reach 50 tonnes/hour – up from 40 tonnes/hour – enabling daily production exceeding 800 tonnes, a milestone in high-purity paraffin manufacturing.
Addressing Production Bottlenecks The breakthrough centered on revitalizing the feed depropanizer column in the preprocessing unit.
This critical infrastructure, responsible for crude oil separation, had suffered from:
• Severe corrosion in air-cooled condensers due to aggressive feedstock
• Pressure escalation from accumulated sludge deposits
• Forced reduction of liquid paraffin output (+15% energy intensity) to maintain operations Strategic Maintenance Execution Executed between April 8-12, 2025, the comprehensive system revamp included:
✅ Pre-maintenance stockpiling of intermediates ensuring continuous downstream supply
✅ Systematic shutdown protocol: circulation-cooling-deoiling-steam cleaning
✅ Condenser replacement & internal anti-corrosion surface renewal
Industry Implications
The restoration delivers dual competitive advantages: Enhanced capacity reliability for global paraffin supply chains Stabilized operating costs amid volatile energy markets With Fushun Petrochemical controlling China’s premier paraffin industrial cluster (Liaoning Province), this operational excellence reinforces its position as a low-cost, high-volume producer meeting 12% of global demand. Fushun Petrochemical – A SINOPEC subsidiary – operates Asia’s largest integrated paraffin facility with 1.2Mton/year production capacity, specializing in Industrial-grade paraffins.
