Question

2. What products are obtained by fraction distillation of
petroleum? What are their uses?​

Answer 1

Answer:

Fractions that are separated out include gasoline, diesel, kerosene, and bitumen. Fractional distillation allows a lot of useful products to be made from crude oil, with many environmental consequences for the use of those useful products

Answer 2

The crude petroleum oil obtained from oil field, undergoes fractional distillation and a number of products are generated. These products of fractional distillation include, petrol (or gasoline), naptha, kerosene, diesel oil, lubricating oil, fuel oil, grease and wax, and some residue. The basic idea is to heat the crude oil and then separate out the various fractions in a fractional distillation column. The crude oil vapors rise up in the column and condense at different heights, according to their boiling points. These products of fractional distillation are used for various purposes in our daily lives. Petrol (or gasoline) and diesel are commonly used for running our vehicles, which operate on petrol or diesel engines. Kerosene is commonly used in developing and underdeveloped countries for cooking. It is also used as jet fuel.

Various fractions obtained during the fractional distillation (refining) of petroleum (or crude oil) are given. The various products obtained during the fractional distillation (refining) of petroleum (or crude oil) can be divided into two categories viz., Petroleum products used as fuels: Petroleum gas (or liquefied Petroleum gas), petrol (gasoline), kerosene, diesel, fuel oil. Petroleum products not used as fuels: Petroleum ether, Lubricating oil, Greases, Petroleum jelly, paraffin wax, pitch.
