The oil refining course of starts with a fractional distillation column.

The issue with crude oil is that it contains hundreds of various kinds of hydrocarbons all blended collectively. It’s a must to separate the several types of hydrocarbons to have something useful. Thankfully there is an easy option to separate issues, and this is what oil refining is all about.

Totally different hydrocarbon chain lengths all have progressively increased boiling points, to allow them to all be separated by distillation. That is what occurs in an oil refinery – in one part of the method, crude oil is heated and the completely different chains are pulled out by their vaporization temperatures. Each different chain length has a different property that makes it helpful in a special means.

To grasp the variety contained in crude oil, and to grasp why refining crude oil is so essential in our society, look by way of the following checklist of products that come from crude oil:

Petroleum gas – used for heating, cooking, making plastics

Naphtha or Ligroin – intermediate that can be further processed to make gasoline

Gasoline – motor gas

Kerosene – fuel for jet engines and tractors; starting materials for making other merchandise

Gasoline oil or Diesel distillate – used for diesel fuel and heating oil; starting materials for making other merchandise

Lubricating oil – used for motor oil, grease, different lubricants

Heavy fuel or Fuel oil – used for industrial gas; starting material for making different products

Residuals – coke, asphalt, tar, waxes; starting material for making other products

You will have observed that each one of these products have different sizes and boiling ranges. Chemists take advantage of those properties when refining oil. Look at the subsequent section to find out the small print of this fascinating process.
