Also known as: distillation fractions, straight run streams
Distillation cuts are the output streams from a distillation tower.
- Refinery gas - Made up 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 feedstock, 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 - 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
