Refinery Process Flow
A simplified crude oil refinery: desalting, distillation, conversion units and blending into finished fuels.
Drawing diagram…
What this diagram shows
- Crude is split by boiling point in distillation columns
- Conversion units turn heavy fractions into lighter fuels
- Blending produces petrol, diesel and jet fuel to spec

Refinery process flowchart: crude oil from storage is desalted, heated and fed to the atmospheric distillation column, which separates LPG, naphtha, kerosene, diesel and atmospheric residue. Residue goes to vacuum distillation, whose vacuum gas oil feeds the fluid catalytic cracker (FCC). Naphtha goes to the catalytic reformer, kerosene and diesel to hydrotreaters to remove sulphur. Products are blended into LPG, petrol, jet fuel and diesel; vacuum residue becomes bitumen or goes to a coker.
