What is the main ingredient of natural gas?why is natural gas considered as cleaner fuel as compared to petrol and diesel
Answers
Natural gas : (also called fossil gas) is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
Natural gas is a mixture of gases which are rich in hydrocarbons. All these gases (methane, nitrogen, carbon dioxide etc) are naturally found in atmosphere. Natural gas reserves are deep inside the earth near other solid & liquid hydrocarbons beds like coal and crude oil.
Natural gas is not used in its pure form; it is processed and converted into cleaner fuel for consumption. Many by-products are extracted while processing of natural gas like propane, ethane, butane, carbon dioxide, nitrogen etc, which can be further used.
Natural gas is mainly used as fuel for generating electricity and heat. Natural gas in compressed form is used as fuel for vehicles which is known as CNG. It is used as fuel for boilers and air conditioners worldwide. This is used for making fertilizers also, mainly ammonia.
