1. Backgrounds

• API gravity (American Petroleum Institute gravity)

  Comparing the specific gravity of oil with water

  $$ API={141.5\over d}-131.5 $$

  d : density of crude oil

  (Venezuelan oils: Close to 15 API, Middle east oils: Close to 40 API)

• Light ends are the light hydrocarbon gases and liquids that come off the top of distillation towers and fractionators. This usually includes refinery gas and some C3s and C4s.

• Braun K10

  Braun K10 is used when the component of crude oil has heavy hydrocarbon or in low-pressure process (<700kPa)

  The error is large when there are much acid gas or light hydrocarbon

• Specific gravity

  Light crude < 0.825

  0.825 < Medium crude < 0.875

  0.875 < Heavy crude < 1.000

  Extra heavy crude > 1.000

2. Objective

A flash vaporization curve is to be generated for a crude oil mixture as the first step in the design of a crude unit
