fractional distillation of petroleum mixture

It is the most important of the fossil fuels. Petroleum occurs under the Earth's crust. It is believed to have formed due to the bacterial action of decomposition on marine animals and prehistoric forests inside the Earth, under conditions of high temperature and pressure. Petroleu..

The fermented liquor contains 9-10% of ethanol and is called wash or wort. It is distilled in a Coffey still (Distillation of wash in a Coffey still) to remove water and other impurities present in wash . The Coffey still consists of two tall fractionating column..

Crude oil or petroleum pumped out of an oil well, is a viscous and complex mixture of several hydrocarbons and small amounts of other compounds. It is not useful in this state. The 'refining of (crude) petroleum' involves the process of fractional disti..

The digested reaction mixture, on cooling, is transferred to a round bottomed distillation flask, and distilled with a concentrated alkali solution (NaOH). Ammonia produced is absorbed in a known volume of HCl solution of a known strength...

Petroleum - Petroleum is a dark, viscous, foul smelling liquid, a mixture of solid, liquid and gaseous hydrocarbons with traces of salt, rock particles and wat..

Distillation is a method used to separate a solute and a solvent from a solution. In evaporation, vaporization takes place and only the solute is obtained. However, distillation is actually a combined process of vaporization and condensation. In distillation, bot..

Petroleum is brought to the surface by drilling a hole in the Earth's crust and sinking pipes deep down through the impervious cap rock. Natural gas first comes out under high pressure. Then, petroleum is pumped out, collected in tanks and transported, for further processing. ..

This liquid air contains two main substances, nitrogen and oxygen in liquid forms whose boiling points are -196 o C and -183 o C respectively. So when this liquid air is allowed to warm up, nitrogen with low boiling point boils over first and is separated. What remains behind is liquid oxygen, whi..

The outgoing hot vapors from the main iron still preheat coal tar obtained from the destructive distillation of coal, in a pre-heater. In this process, coal tar loses most of the water it contains, along with some low boiling hydrocarbons. It is then sent to the main iron still (a side r..
