distillation process of petroleum

Separation of the Constituents of Mixtures - Distillation - 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 pro..

Due to the small difference in the boiling points, both liquids form vapors simultaneously. Vapors of the boiling liquid mixture are made to pass through a glass fractionating column. The fractionating column is a simple packed column, packed with glass beads, or it is a specially designed column ..

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..

Distillation under reduced pressure or vacuum is carried out in a specially designed glass apparatus. A two necked 'Claisen's flask' is used, the main neck of which is fitted with a long capillary tube and the side neck being fitted with a thermometer. The side tube is connected to a con..

Crude petroleum is pumped into the furnace where it is heated to a temperature of about 400 o C. Petroleum is converted to vapours in the furnace. The vapours of petroleum are fed into the fractionating column from the bottom. As the vapours enter the column, t..

The mixture to be separated is taken in a suitable solvent and the solution is poured on the top of the column of the adsorbent. It is allowed to pass slowly through it and as it passes through the column the different constituents of the mixture get adsorbed to different extent, forming bands in ..

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..

In this process, powdered coal is mixed with heavy oil and heated with hydrogen under high pressure (200-250 atm) at about 748 K in presence of iron oxide as catalyst...
