Transcript of Distillation
for example : distillate crude oil.
it can contribute to more than 50% of plant operating costs
by Naeema, Shayan, Henna and Shakhana
The usual purpose of distillation is purification of the components of a mixture. This is possible because the composition of the vapour is usually different from that of liquid mixture from which it is obtained. Petrol, kerosene, fuel oil, and lubricating oil are produced from petroleum by distillation
This is a diagram of a distillation experiment.
Examples of distillation
A process in which a liquid or vapour is divided into different components by application and removal of heat.
An example of disstilation would be the fractional disstilation of crude oil. Crude oil is heated to 350 degrees celcius. it is then pumped into the bottom of a fractioning tower.
Most of the substances in the crude oil evaporate. The mixture of vapours then passes up the tower. The tower is steadily cooler towards the top. The different hydrcarbons have different boiling points as they condense at different levels up the tower. Special trays collect the condensed liquid and it runs off in pipes.
The products are (small molecules-large molecules):
- Refinery gases
- Gasoline (peterol)
- Diesel oil
- Fuel oil
- Residue (bitumen)
- Boiler, heating pad,splitting tube and thermometer
- Water supply hose and draining tube
- Clamps and fittings.
Water purification - Separation of materials
Separation of crude oil where it seperates components of boiling points
