Crude Oil Refining, An Essential Process

Crude oil first needs to be refined into other products before it can be used by consumers and industry. The process involves separating the large number of hydrocarbon molecules present in the oil into various components. Some of the molecules are very light and are in gas form, while others are very heavy. Refining converts oil into a broad range of marketable products, including gases (butane and propane); fuels (gasoline, diesel and kerosene); naphtha (a petrochemical feedstock); heating oil; base oils and asphalt for paving roads.
