Natural Gas

Unreproducible resources are usually formed like oil which is the product of decomposition of organic matter by ancient marine microorganisms and the water areas where mud, silt and sand remain mixed in the seabed gradually gradually It is filled. It is sealed in oxygen-free environment and exposed to heat and pressure rise, so organic matter is converted to hydrocarbon via pyrolysis process. The lightest of these hydrocarbons is in a gaseous state under normal conditions, and is collectively referred to as natural gas.

Natural gas occurs deep in the surface of the earth. Natural gas is composed mainly of methane, compounds having one carbon atom and four hydrogen atoms. Natural gas also contains small amounts of hydrocarbon gas liquids and non-hydrocarbon gases. Natural gas is used as fuel for manufacturing raw materials and chemical products. Millions of years ago, animal and plant remnants (diatoms) rotted to form a thick layer, sometimes mixed with sand and silt. Over time, these layers are buried in sand, silt and rock. Pressure and heat convert organic matter to coal, some to oil (oil), and some to natural gas. In some places, natural gas moves into large cracks or spaces between the upper layers. Elsewhere, natural gas occurs in small holes (spaces) in specific layers of shale, sandstone and other types of sedimentary rocks, where it is called shale gas or tight gas.

Natural gas is a fossil fuel produced by decomposition of organic matter in anaerobic environments (usually from ancient marine life). There are two types of natural gas reserves: conventional type and non-conventional type. Conventional deposits are related to oil reserves such as mineral deposits that are not molded, coalbed methane, shale gas, tight sandstone and so on. Like natural gas, petroleum is produced by organic decomposition under anaerobic conditions for millions of years. Petroleum supplies 40% of the national energy demand for the production of gasoline, diesel, jet fuel, propane, asphalt. Petroleum is also used for the manufacture of petrochemical products such as plastics, synthetic rubber, chemicals, etc.

Coal is solid, petroleum is liquid, and natural gas is steam (gas). Over the years, under high pressure conditions coal and oil have been formed from deposits of deep underground plants and animals. Natural gas is also formed by these processes, but natural gases can be generated relatively quickly in the city gas landfill sites, waste disposal plants, etc. due to decomposition of organic matter. Coal is primarily obtained by mining, but oil and natural gas are extracted from wells excavated to the ground from land or sea platforms.
