Write about Petroleum in detail, in more than 100 words

Answer 1

Petroleum is a fossil fuel. It is called a fossil fuel because it was formed from the remains of tiny sea plants and animals that died millions of years ago. When the plants and animals died, they sank to the bottom of the oceans. They were buried by thousands of feet of sand and silt.

Over time, this organic mixture was subjected to enormous pressure and heat as the layers increased. The mixture changed chemically, breaking down into compounds made of hydrogen and carbon atoms—hydrocarbons. Finally, an oil-saturated rock—much like a wet household sponge—was formed.

All organic material does not turn into oil. Certain geological conditions must exist within the oil-rich rocks. First, there must be a trap of non-porous rock that prevents the oil from seeping out, and a seal (such as salt or clay) that keeps the oil from rising to the surface. Even under these conditions, only about two percent of the organic material is transformed into oil.

✨Heya!!!!✌

✍Your answer⬇⬇⬇⬇

Petroleum is a dark coloured viscous liquid and is a complex mixture of compounds containing mainly carbon and hydrogen. Petroleum is found beneath the earth's surface and is formed by the decay of tiny marine animals and plants burried under the earth about 400 million years ago. Petroleum is also a fossil fuel and in its natural form is known as crude oil. It is pumped out by drilling holes. Major oil producing countries in the world are Saudi Arabia, Iraq, Iran, Kuwait, USA and Russia.

In India, the oil wells are found onshore in Assam and Gujarat and off shore at Bombay High and the Godavari basin.

Petroleum in its crude form cannot be used as such. Petroleum is therefore, separated into its constituents fractions for their proper utilisation by the process known as fractional distillation. It is based on the fact that different fractions of petroleum boil within different temperature ranges.
The different fractions of the petroleum are:

⏩Petrol/gasoline used as motor fuel.

⏩Kerosene used as fuel in jet engines, for domestic purpose.

⏩Diesel fuel used in diesel engines, in industries.

Other fractions are petroleum wax, lubricating oil. There are seventeen refineries in India. Some of these refineries are at Mathura, Bharouch, Digboi and Haldia.
