ExxonMobil’s Singapore Resid Upgrade Project is progressing steadily, emphasizing modular construction to accelerate deployment and reduce on-site footprint. Several reactors stand over 50 meters tall, with modules transported from off-site fabrication yards to the refinery complex in multiple shipments.

The project focuses on converting low-quality resid into higher-value base stocks and fuels, including EHC™ 50 and EHC 340 MAX™. Once operational, the upgrade will enhance the refinery’s ability to produce premium lubricant derivatives from heavier feedstocks. The modular approach reduces field risks and allows parallel construction, streamlining timelines and resource allocation—especially critical for ultra-complex upgrades in dense refinery zones.

Technical integration with the existing process chain ensures that the new resid conversion units harmonize with downstream catalysts and heat recovery systems. As global refiners increasingly target heavier crudes and demand more lubricant output, such retrofit projects highlight the shift toward refining flexibility and value capture.
