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.
