Petroleum
Petroleum or Crude Oil, is composed of thousands of
organic molecules called hydrocarbons.
Crude from various sources has different properties
and is characterized as sour or sweet, meaning high or
low sulfur; light or heavy, meaning less or more
density; and Asphaltic or Wax based.
Generally light, waxy, and low sulfur make the value
more.

Petroleum is processed by simple distillation
into about 5 products:
Naphtha or gasolines - reprocessed to increase
octane
Kerosine –goes to Jet Fuel
Diesel – goes to finished diesel or furnace oils
Gas Oil – goes to lubricating oil or cracked into
gasoline
Residuum – very heavy – wax, road oils and
asphalts, Fuel Oil, or cracked to gasoline
Extensive and expensive reprocessing of these
products to remove contaminants such as sulfur,
metals, nitrogen, and other substances to improve
