Question

Which of the following is/are the main components present in LPG?
(A) Methane
(B) Propane
(C) Butane
(D) Both B and C

Answer 1

Hint: LPG is defined as liquid Petroleum gas which is considered to be a flammable mixture of some hydrocarbon gases which are further used in heating appliances, vehicles.

Complete step by step solution:
> Liquid petroleum gases are helping us in reducing the number of chlorofluorocarbons present in the environment and also helping us introduce the damage we give to our Ozone Layer. Most commonly used components of liquid Petroleum gas are Propane and Butane. Propylene, butylene and other different kinds of Hydrocarbons are also present in very small amounts. Ethanethiol all is a very powerful odorant and is used in liquid Petroleum gas so that the leakage can be detected as the Ethanethiol has a very harsh smell and produces discomfort in breathing. Internationally tetrahydrothiophene or amyl mercaptan are being used as odorants. As liquid Petroleum gas is made up by wet natural gas which has been derived from fossil fuels, they are less harmful to our environment.
> Liquid Petroleum gas does not cause any water choking or water pollution. The calorific value of liquid Petroleum gas is 46.1 MJ/kg. Which is defined as the particular amount of heat that has been released during a combustion process. The boiling point of liquid Petroleum gas is below the room temperature so it gets evaporated quickly at normal pressure and temperature. Liquid Petroleum gas is usually kept in stainless steel vessels. The amount of pressure at which the liquid Petroleum gas converts into liquid is known as vapour pressure. The vapour pressure also depends on the temperature pressure.

The correct answer is D.

Note: Liquid Petroleum gas can flow on the floors as it is heavier than the normal air as it is a natural gas. When liquid Petroleum gas gets mixed with the air it may get exploded.
