Natural Gas

A natural gas alternative energy sources for fuel oil from high-efficiency low-cost low- polluting emissions. Natural gas important primary energy source for the chemical industry.

Natural gas consists of plankton, a micro-organisms including algae and organisms initial died and built up in layers of the oceans and the earth, and remains under sedimentary layers. And over the millennia has pressure and temperature resulting from the sedimentary layers convert these organic materials to natural gas, natural gas does not differ much in its formation from other fossil fuels such as coal and oil . As oil and natural gas under the same natural conditions, these compounds usually passing by together in the fields under the ground or water, generally layered sedimentary organic buried in depths ranging between 1000 to 6000 meters (at temperatures ranging from 60 to 150 ° C) produces petrol while those buried deeper and at higher temperatures produces natural gas, and the greater the depth of the source whenever drier (i.e. less than gas condensates). After formation gradual in the earth's crust leaking natural gas and oil slowly to small pits in the porous rock nearby that operate warehouses to save raw, because these rocks are usually filled with water, the oil and natural gas - both lighter than water and less dense than the surrounding rock - passed down for higher across crust sometimes long distances. In the end trapping some of these hydrocarbons transmitted to the top of the layer is not porous (non-waterproof) of rock known as rock cover (Cap Rock), and because natural gas is lighter than oil who shall configure layer above the oil called cover gas (Gas Cap). It must be accompanied by petroleum gas called associated gas (Associated Gas), also contain coal mines amounts of methane - the main component of natural gas - and in coal seams sedimentary distracted methane often through pores and cracks of the mine, called this type commonly methane coal mines .
