Fractional distillation of crude oil is a process used to separate the different components of crude oil based on their boiling points. Crude oil is heated in a distillation column, and as it vaporizes, the different components with higher boiling points condense at different levels in the column. This allows for the separation of components such as gasoline, diesel, kerosene, and other petroleum products. Each component can then be further refined and processed for various industrial and commercial uses.

Fractional Distillation of Crude Oil
Fractional distillation is a separation process used to refine crude oil into various fractions based on their different boiling points. It separates complex mixtures of hydrocarbons into their constituent components, each with a distinct range of boiling temperatures.
Process:
1. Pre-heating: Crude oil is pre-heated to reduce its viscosity and facilitate separation.
2. Distillation Column: The pre-heated oil enters a tall, vertical column called a distillation column. The column consists of multiple trays or plates arranged in sections.
3. Temperature Gradient: The temperature inside the column varies from high at the bottom to low at the top. At the bottom, the temperature is hottest, causing the most volatile components to evaporate.
4. Condensation and Collection: As the vapors rise through the column, they condense at different heights based on their boiling points. Lighter, more volatile components like natural gas, gasoline, and kerosene condense on the higher trays. Heavier components like diesel, lubricating oils, and bitumen condense on the lower trays.
5. Draw-off: The condensed fractions are collected from the side of the column at specific levels corresponding to their boiling point ranges.
6. Side Streams: Often, side streams are removed from the column to produce specialized products such as jet fuel, naphtha, or solvents.
Resulting Fractions:
Fractional distillation separates crude oil into the following primary fractions:
- Natural Gas: Lowest boiling point, lightest fraction.
- Liquefied Petroleum Gas (LPG): Used as cooking fuel.
- Gasoline: Used as fuel for vehicles.
- Kerosene: Used as fuel for jets and lamps.
- Diesel: Used as fuel for trucks and heavy machinery.
- Lubricating Oils: Used to reduce friction in engines.
- Fuel Oil: Used as fuel for power plants and ships.
- Bitumen: Used in road construction and roofing.
Benefits:
- Efficient separation of crude oil into valuable products.
- Maximization of yields of specific products.
- Production of high-quality fuels and other products.
