Topping Unit
Specification
- Topping units primarily consist of crude distillation which produces first cut of Naphtha, Kerosene, Diesel and Residue Distillates.
- Quality and quantity of this first cut product depends on assay of incoming crude.
- The incoming crude is first taken into a desalter, then into a heater to heat it to 1,292 °F (700 °C).
- It is then fed into the distillation column where the top part extracts Gas, Naphtha and Kerosene, and the downcomers collect Diesel and Residues.
- These are primarily built into modular capacities of 3,000 barrels per day – 20,000 barrels per day.
- • These are useful for remotely located oil fields.
