Question

How is petroleum refined

Answer 1

Answer:

Deposition of petroleum occurs with natural gas in the rocks called oil wells from where it is taken out by drilling. Refining is a process where the separation of various compounds of crude oil occurs. Fractional distillation is a process used to separate its compounds.

Crude Oil procured from an oil well is a mixture of many liquids. Different temperature evaporates a different liquid. This temperature is the boiling point of that liquid. The crude oil is heated to a temperature of 400-degree Celcius, is fed in at the bottom of the column and heated further. The liquid with the lowest boiling point changes into vapor first and condenses. At higher temperature, the next volatile liquid changes into a vapor state and rises.
