How Bottom-of-the-Barrel Upgrading Turns Residues into Revenue

When it comes to refining, even the heaviest residues hold untapped value.

As Eberhard Lucke of Lucke Consulting Technology Services (LCTS) explains, bottom-of-the-barrel upgrading is a suite of technologies designed to convert heavy residues—often considered waste—into lighter, more valuable products like diesel, naphtha, and fuel oil.

These residues are typically the byproducts of crude distillation units, vacuum towers, and other upstream processes. While dense and low in hydrogen content, they contain significant hydrocarbon potential—if processed correctly.

Key upgrading technologies include:

Delayed Coking – Cracks heavy residues into lighter hydrocarbons and solid petroleum coke using high heat in a controlled drum environment.

Visbreaking – A milder form of thermal cracking that reduces the viscosity of heavy oils and improves their flow characteristics while producing light distillates.

Thermal Cracking – Breaks down complex molecules at high temperatures to maximize the yield of transport fuels.

By applying these technologies, refiners can:

✅ Boost overall product yield
✅ Reduce environmental impact by minimizing waste
✅ Generate saleable byproducts like petroleum coke
✅ Improve refinery margins and asset utilization
✅ Handle a wider range of crude slates, including heavier grades
