In this video, it is explained in detail how the crude oil which is also called “black gold”, how it is made under the earth, how it is taken out and then how is it converted into petrol and diesel in the refinery. According to the video, millions of years ago, animals and plants living in the sea were buried under the soil and rocks. Due to excessive pressure and heat on it, they turned into crude oil and natural gas. Scientists use sound waves to locate these reserves. Then this oil is taken out by digging from big oil rigs. In the refinery, crude oil is heated and divided into different parts, because the boiling temperature of each product is different. The heaviest parts remain down, while light parts such as petrol and LPG gather at the top. This entire process is called ‘Fraudled Distillation’, only after which we get fuel for our vehicles.
