Liquefied natural gas - fuel of the future

Liquefied petroleum gas is universal synthetic mixture of propane, butane and minor amounts of unsaturated hydrocarbons, obtained by extraction of oil and its subsequent processing.In principle, such a mixture is a by-product of oil production, so to speak, a nice bonus.In developing the fields of "black gold" is an allocation of associated petroleum gas (APG), which was then at the enterprises of the relevant profile is processed into liquefied natural gas.

For every ton of crude oil falls from fifty to five hundred cubic meters of associated gas, which is sent along with the main product to a refinery, where it made its compression (liquefaction).Liquefied natural gas is obtained from NGLs (natural gas liquids), which stands out from APG.Then the mixture is compressed under high pressure without changing the temperature.

liquefied gas intended for industrial use and heating of various buildings, is stored in special ground or underground tanks - gas holders.According to this indicator, the amount of energy released, the fuel from the hydrocarbon components is second only to the main natural gas.

Liquefied hydrocarbons are an important raw material of petrochemical industry.For manufacturing various products such gases are subjected to a pyrolysis process, which takes place at very high temperatures.As a result, the compounds of olefins (ethylene, propylene, etc.) - Acyclic unsaturated hydrocarbons having one double bond between the atoms.Then, these complex compounds by the polymerization process are converted to different kinds of polymers and plastics (polyethylene, polypropylene, etc.).So every day we use packing containers, disposable dishes and a variety of everyday objects were once liquefied gases.

But the main purpose of such gaseous mixtures is different.In light of some of the problems in the energy sector against the backdrop of the general economic crisis and underlined the international community cares about the environmental situation in the world liquefied natural gas becomes extremely urgent and could soon take a leading position as a motor fuel.Environmentally friendly fuel, which is important.

Even today, the world fleet of vehicles using liquefied hydrocarbon, has more than 20 million. Units of vehicles.Also LPG is widely used for heating homes and buildings of huge industrial plants, drying, cutting and welding metals.In addition, it takes a strong position in the field of agriculture, where it is used to burn off weeds and pests.

Magnificent environmental, economic and heat engineering qualities that have fully liquefied petroleum gas, make it an ideal source of energy today and tomorrow.He is able for many years to solve energy and environmental problems of humanity.
