Natural Gas प्राकृतिक गैस
प्राकृतिक गैस (Natural gas) कई गैसों का मिश्रण है जिसमें मुख्यतः मिथेन होती है तथा ०-२०% तक अन्य उच्च हाइड्रोकार्बन (जैसे इथेन ) गैसें होती हैं। प्राकृतिक गैस ईंधन का प्रमुख स्रोत है। यह अन्य जीवाश्म ईंधनों के साथ पायी जाती है।
यह करोडों वर्ष पुर्व धरती के अन्दर जमें हुये मरे हुये जीवो के सडे गले पदार्थ से बनती है। यह गैसिय अवस्था मे पाइ जाती है। सामान्यत यह मेथेन, एथेन, प्रोपेन, ब्युटेन, पेन्टेन का मिष्रण है, जिसमे मिथेन ८० से ९० % तक पायि जाति है। इसके अतिरिक्त कुच असुध्धिया भी पायी जाती है, जैसे सल्फर, जल वास्प, आदि होते है।
Natural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants originally obtained from the sun is stored in the form of carbon in natural gas. Natural gas is a nonrenewable resource because it cannot be replenished on a human time frame. Natural gas is a hydrocarbon gas mixture consisting primarily of methane, but commonly includes varying amounts of other higher alkanes and even a lesser percentage of carbon dioxide, nitrogen, and hydrogen sulfide. Natural gas is an energy source often used for heating, cooking, and electricity generation. It is also used as fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.
Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates. Petroleum is also another resource found in proximity to and with natural gas. Most natural gas was created over time by two mechanisms: biogenic and thermogenic. Biogenic gas is created by methanogenic organisms in marshes, bogs, landfills, and shallow sediments. Deeper in the earth, at greater temperature and pressure, thermogenic gas is created from buried organic material.
Before natural gas can be used as a fuel, it must undergo processing to remove impurities, including water, to meet the specifications of marketable natural gas. The by-products of processing include ethane, propane, butanes, pentanes, and higher molecular weight hydrocarbons, hydrogen sulfide (which may be converted into pure sulfur), carbon dioxide, water vapor, and sometimes helium and nitrogen.
Natural gas is often informally referred to simply as gas, especially when compared to other energy sources such as oil or coal. However, it is not to be confused with gasoline, especially in North America, where the term gasoline is often shortened in colloquial usage to gas.
Natural gas was used by the Chinese in about 500 B.C. They discovered the potential to transport gas seeping from the ground in crude pipelines of bamboo to where it was used to boil sea water in Ziliujing District. The world's first industrial extraction of natural gas started at Fredonia, NY in 1825. By 2009, 66 trillion cubic meters of natural gas had been used out of the total 850 trillion cubic meters of estimated remaining recoverable reserves, representing the usage of 8% of economically recoverable global reserves of natural gas. At estimated 2015 world consumption rate of about 3.4 trillion cubic meters of gas per year, the total estimated remaining economically recoverable reserves of natural gas would last 250 years
