Heavy oil refineries lose capacity with light crude because their equipment—designed for heavy, high-viscosity feedstock—becomes overwhelmed by the higher volume of light naphtha and gases produced, causing distillation tower flooding. Additionally, these plants lack sufficient downstream capacity (reforming/isomerization) to process the excess light materials.
Key Reasons for Capacity Loss:
Tower Flooding: Light crude produces roughly three times more light gases (methane, propane, butane) than heavy crude, exceeding the capacity of the top of the distillation tower.
Equipment Mismatch: Units designed for heavy oil (like cokers and vacuum towers) become underutilized, while units designed for light products (reformers, alkylation units) get overloaded.
Furnace Limitations: The increased volume of lighter, vaporized material can exceed the capacity of furnaces to heat the crude oil, forcing operators to lower the total feed rate.
If you say so..................smh
Your last sentence makes no sense at all. Refining equipment/furnaces can be and are adjusted for various conditions. I could go into that, but you wouldn't believe it anyway.
As I tried to say, most were built before heavy crude was a big thing, then added on and modified for heavy,
