Unlocking current refinery constraints

When processing heavy feeds, technology based on residuum supercritical solvent extraction provides higher volumes of gas oil and DAO for conversion units. Potential constraints through existing vacuum and coker units can also be resolved.

Chemical treatment strategies for processing heavy crude oil

Desalting, solids and metals removal, and preheat fouling control are just some of the challenges currently facing the heavy processing industry. Crude compatibility studies for heavy oil blending can prevent the precipitation of asphaltenes and, with the use of desalting aids, additives and preheat antifoulants, a 75% reduction in fouling can be achieved.
