natural gas benefits

Understanding the Advantages of Natural Gas

Natural gas is often also referred to as natural gas or marsh gas, is a gaseous fossil fuel consisting primarily of methane CH4). He can be found in oil fields, gas fields and coal mines. When the gas is rich in methane produced by anaerobic bacterial decomposition of organic materials other than fossil, then it is called biogas. Sources of biogas can be found in marshes, rubbish dumps, as well as the disposal of human and animal waste.

The chemical composition

The main component in natural gas is methane (CH4), which is a chain hydrocarbon molecules shortest and lightest. Natural gas also contains molecules heavier hydrocarbons such as ethane (C2H6), propane (C3H8) and butane (C4H10), as well as gases containing sulfur (sulfur). Natural gas is also a major source of helium gas source.

Nitrogen, helium, carbon dioxide (CO2), hydrogen sulfide (H2S), and water can also be contained in natural gas. Mercury can also be contained in a small amount. The composition of natural gas varies according to the source of the gas fields.

3 Top Benefits or advantages of Natural Gas

Natural gas has now become an alternative energy source that is widely used by the world community for a variety of purposes, either for residential, commercial and industrial. From year to year, the use of natural gas is increasing. This is because of the many benefits of the use of natural gas compared with other energy sources. The energy produced natural gas more efficiently. Unlike petroleum and coal, its use is much more clean and very friendly environment so as not to cause pollution to the environment. In addition, natural gas also has some other advantages, such as a colorless, odorless, non-corrosive and non-toxic.
Broadly speaking, the utilization of natural gas is divided into 3 groups:

1. Natural gas as fuel
Partly as a power plant fuel gas / steam, industrial fuel light, medium and heavy, automotive fuel (CNG / NGV), as for household purposes hotels, restaurants and so on. Compressed natural gas (Compressed natural gas, CNG) is an alternative fuel other than gasoline or diesel. The fuel is considered to be 'clean' when compared with the two fuel oil for gas emission environmentally friendly. CNG is made by compressing methane (CH4), which is extracted from natural gas. LPG (liquified petroleum gas), is a mixture of hydrocarbons of various elements derived from natural gas. By increasing pressure and decreasing temperature, the gas turns into liquid. Components are predominantly propane (C3H8) and butane (C4H10). LPG also contain other light hydrocarbons in small quantities, for example, ethane (C2H6) and pentane (C5H12).

2. Natural gas as a raw material
Among other raw materials fertilizer plants, petrochemicals, methanol, plastic raw materials LDPE (low density polyethylene), LLDPE = linear low density polyethylene, HDPE (high density polyethylen), PE (poly ethylene), PVC (poly vinyl chloride), C3 and C4 her for LPG, its CO2 for soft, dry ice food preservatives, artificial rain, industrial iron castings, welding and light a fire extinguishing agent.

3. Natural gas as an energy commodity for export
The biggest natural gas used for export commodities in the world, LNG (Liquefied Natural Gas) or liquefied natural gas.
LNG Liquefied Natural Gas (LNG) is natural gas that has been processed to remove impurities and heavy hydrocarbons and then condensed into liquid in the atmosphere with cool tap around -160 ° Celsius.
