Flowserve refinery flowsheet

• 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
