From Crude Oil – How Oil Refining Works
This content material shouldn’t be suitable on this system.
The oil refining course of starts with a fractional distillation column.
The issue with crude oil is that it contains hundreds of several types of hydrocarbons all combined collectively. It’s important to separate the different types of hydrocarbons to have anything helpful. Fortuitously there’s a straightforward solution to separate things, and this is what oil refining is all about.

Totally different hydrocarbon chain lengths all have progressively greater boiling factors, to allow them to jingbo petroleum machinerympany rankings all be separated by distillation. That is what happens in an oil refinery – in a single a part of the method, crude oil is heated and the completely different chains are pulled out by their Kinetic Energy vaporization temperatures. Every totally different chain size has a distinct property that makes it helpful in a distinct method.
To know the range contained in crude oil, and to grasp why refining crude oil is so necessary in our society, look by means of the next list of merchandise that come from crude oil:
Petroleum gasoline – used for heating, cooking, making plastics
small alkanes (1 to 4 carbon atoms)
generally known by the names methane, ethane, propane, butane
boiling range = less than 104 levels Fahrenheit / forty levels Celsius
often liquified below pressure to create LPG (liquified petroleum gasoline)
Naphtha or Ligroin – intermediate that will likely be further processed to make gasoline
mix of 5 to 9 carbon atom alkanes
boiling range = 140 to 212 degrees Fahrenheit / 60 to 100 degrees Celsius
Gasoline – motor fuel
mix of alkanes and cycloalkanes (5 to 12 carbon atoms)
boiling range jingbo petroleum machinerympany rankings = 104 to 401 levels Fahrenheit / forty to 205 levels Celsius
Kerosene – fuel for jet engines and tractors; beginning material for making different products
mix of alkanes jingbo petroleum machinerympany rankings (10 to 18 carbons) and aromatics
boiling vary = 350 to 617 levels Fahrenheit / 175 to 325 degrees Celsius
Gasoline oil or Diesel distillate – used for diesel fuel and heating oil; beginning material for making other merchandise
alkanes containing 12 or extra carbon atoms
boiling vary = 482 to 662 levels Fahrenheit / 250 to 350 degrees Celsius
Lubricating oil – used for motor oil, grease, other lubricants
lengthy chain (20 to 50 carbon atoms) alkanes, cycloalkanes, aromatics
boiling vary = 572 to seven hundred levels Fahrenheit / 300 to 370 degrees Celsius
Heavy gasoline or Gasoline oil – used for industrial gas; starting materials for making different products
lengthy chain (20 to 70 carbon atoms) alkanes, cycloalkanes, aromatics
boiling range = seven-hundred to 1112 levels Fahrenheit / 370 to 600 levels Celsius
Residuals – coke, asphalt, tar, waxes; beginning material for making other merchandise
a number of-ringed compounds with 70 or more carbon atoms
boiling range = greater than 1112 degrees Fahrenheit / 600 degrees Celsius
You may have noticed that each one of these merchandise have totally different sizes and boiling ranges. Chemists take benefit of these properties when refining oil. Take a look at the following section to search out out the details of this fascinating process.
