USA HISTORY

Detailed explanation-1: -The crude is heated by a furnace and is sent to a distillation tower, where it is separated by boiling point. Then the material is converted by heating, pressure or a catalyst into finished products including fuels like gasoline and diesel, and specialty products like asphalt and solvents.

Detailed explanation-2: -Kerosene is produced by fractional distillation of crude oil in an oil refinery. It condenses at a temperature intermediate between diesel fuel, which is less volatile, and naphtha and gasoline, which are more volatile.

Detailed explanation-3: -A refinery is similar to a giant chemistry set that takes crude oil and refines it into different products like gasoline, diesel, aviation fuel, and naphtha (commonly used as a paint thinner).

Detailed explanation-4: -Kerosene fuel is a petroleum product that is produced by separating the compounds which make up crude oil. This process is known as ‘fractional distillation’ and leaves a clear and thin oil which is roughly 0.81 g/cm³ (gram per cubic centimetre) in density.

Detailed explanation-5: -The refining process. Every refinery begins with the separation of crude oil into different fractions by distillation. The fractions are further treated to convert them into mixtures of more useful saleable products by various methods such as cracking, reforming, alkylation, polymerisation and isomerisation.
