Visit this site for interesting facts and information about Gas Energy. Learn about Gas Energy. Description together with definition of Gas Energy.
Gas energy is also known as natural gas energy. Natural gas is also a fossil fuel like oil. And it is also a non-renewable energy similar to oil energy because it can’t be replaced in human time-frame. It is formed when plants and animals, which store the solar energy in them, gets buried inside the earth and due to heat and pressure applied over a span of 1000 years.
Natural gas is a mixture of hydrocarbon gas. Its main constituent is methane of the alkane family. It also consists of various other higher order alkanes such as ethane, butane and others in varying proportions. It might also consist of small quantities of carbon dioxide, nitrogen and hydrogen sulphide.
It is primarily used for domestic purpose, mainly for cooking.
It is used for heating, and electricity generation.
In some places it is also used as an automobile fuel.
And it is also used in some industries, mostly the plastic manufacturing industries.
Natural gas is extracted from the earth by blind extraction and well drilling.
In blind extraction, the geological exploration is done and the depth at which the natural gas is located is found out. The natural gas are found at the fine pores of various rocks that are below the ground and the depth varies from 1000 meters to several kilometers.
In well drilling, there are specially built wells called the producing or operating wells that are used for extracting the natural gas.
Before natural gas is used as a fuel, it must undergo various processes to remove various impurities. Some of the by-products that are produced during these processes are ethane, propane, butane, pentane, carbon dioxide, hydrogen sulphide, water vapor, helium and nitrogen.
Unlike production of solid fossil minerals, the main feature of gas production is that gas remains in sealed structures at all times from its extraction to the moment of its delivery to consumer.
Natural gas produces 45% less carbon dioxide than coal while burning.
Museums use natural gas-fueled equipment to help maintain the proper humidity for the conservation of art, fabrics and historic papers.
If all the natural gas pipelines in the U.S. were connected to each other they would stretch to and from the moon almost three times.
Natural gas in its pure form is colorless and odorless. Utility companies add the smell of rotten eggs - a product called mercaptan - to make natural gas detectable.
There are more than 120,000 natural gas vehicles on American roads, as many companies and municipalities are deploying fleets of natural-gas powered vehicles to reduce emissions.
Natural gas is efficient. About 90 percent of the gas produced is delivered to customers as usable energy. Greater efficiency means fewer greenhouse gas emissions.
