Also known as: distillation fractions, straight run streams
Distillation cuts are the output streams from a distillation tower.
- Refinery gas - comprised of methane and ethane. This stream remains a gas and is sent to the fuel system.
- Propane - blended into LPG or used for refinery fuel
- Butane - blended into LPG or used as refinery fuel
- light straight run naphtha - sold as a petrochemical feed stock, blended into gasoline, or upgraded through isomerization
- Heavy naphtha - mostly upgraded through the reformer
- Kerosene - used to make jet fuel or blended into diesel
- Atmospheric gasoil - used to make diesel or converted to gasoline through the FCC
- Atmospheric bottoms - this cut contains all of the hydrocarbons that do not vaporize. It is typically fed to the vacuum distillation unit for further separation.
- VGO or Vacuum gasoil - typically sent to the FCC or hydrocracker to be upgraded into light products
- Vacuum resid - literally the bottom of the barrel. Typically blended into residual fuel oil or upgraded through a coker or visbreaker
