Natural gas contains varying amounts of undesirable impurities in addition to hydrocarbons, combustible, and that should be removed and disposed of, in order to become a gas suitable for different uses. The most important of these materials, impurities, water vapor and nitrogen gas and hydrogen sulfide and carbon dioxide, argon and helium, and sometimes small amounts of elemental mercury.
And begin the process of purification of natural gas, separation of water vapor by airborne materials by drying in particular, ethylene glycol and a trio of silica and alumina paste. This is followed by natural gas rid of a compound of hydrogen sulfide and carbon dioxide, which is Amtsasma ethanol solution of single-or dual-Secretary of the Secretary of the glycol. The advantage of hydrogen sulfide resulting in the preparation of some important chemical compounds, sulfuric Khaamad, the carbon dioxide associated with natural gas We learn several things from it in some industries, food and soft drinks in the mobilization of fire fighting equipment.
In case of natural gas containing mercury are disposed of in several ways, most notably the use of sulfur-impregnated activated carbon, or caught doping with alumina or use some Kmahlol solutions of potassium permanganate.
Separate the components of natural gas
After the stage of purification of natural gas from its impurities, starting hydrocarbon phase separation of its constituent components. Valmithan and ethane are separated for use as fuel in some industries and in power generation. Are also separate each of propane and butane for use in the domestic sector and Moafatthma often according to the percentages that are required and as the seasons change, becoming more and more percentage of butane in summer and less in winter. These gases are sold either through a pipeline network for distribution or packed in special steel cylinders under pressure, note that the gas is odorless and a special substance is added to impart a distinct odor to warn him in case of leakage. The components of other hydrocarbons, including propane and butane, are utilized as feedstock in the petrochemical industries, some of the task.
Liquefaction of natural gas
Requires the transfer of natural gas from one place to another, or stored in containers in particular, to convert from a gas to a liquid state, a so-called term gas liquefaction, is called in this case natural gas (LNG).
The idea of the liquefaction of gas in the United States of America in 1914, patented, and in 1917, established the first commercial unit for the liquefaction of natural gas in West Virginia in America, and the subsequent global spread of this technology. And resort to the process of liquefying the gas to facilitate the transportation and storage in large quantities, for example, can store 2 million cubic feet of gas in the tank with a diameter of 15 feet and a height of 20 feet and this means that the gas (LNG) takes up less space at 600 times the volume occupied by a in the gaseous state. And is followed several methods for the liquefaction of natural gas, but they all share in exposing the gas pressure exceeds 400 lbs / square inch, and then cooling to a temperature low up to -259 degrees Fahrenheit, and this process is the physical place in the industrial units, burst, and saves gas (LNG) thick metal containers.
Uses of natural gas
Resorted to many countries of the world to use natural gas as fuel to generate electric power, and desalination of sea water, and also as fuel in some of the oil industry, in addition to its use as feedstock in the petrochemical industries, and as a source of hydrogen.
Studies show that about 30% of the total use of natural gas in the Arab states is in the field of electric power generation, and about 36% is used in refineries and oil processing, and about 36% is used in different industrial sectors, and the remaining are used for domestic cooking and heating .
The most frequent natural gas an important place in the world of industry as a source of energy, especially in industries that require large amounts of heat, Kalsnaat metal such as iron, steel, aluminum, and also the manufacture of cement, glass and bricks in addition to its use in some of the chemical industry as raw material, most notably the manufacture of detergents, paints and plastics and paints. Also, some countries used natural gas as a fuel in vehicles that operate within cities. In spite of the positive aspects that can be achieved, but that such technology requires overcoming technical difficulties, multiple, such as the provision of private stations to refuel, and substantial amendments to the combustion system in vehicles, and the accompanying real challenges for the use of compressed gas inside and rolling stock, which extent of use as fuel for transport in general.
Despite the importance of using natural gas as the main source of energy sources, but studies have shown that its use as a feedstock for the production of a large number of important chemical compounds, more useful than burning directly, energy is can be provided from oil or from other sources. Industries are petrochemical based on natural gas as feedstock for the production of a large number of vehicles Calaythelen, propylene, polybutadiene, methanol, ethanol and other dozens of vehicles that are used in turn to produce a very large number of vehicles, materials and chemical products task, such as fertilizers, synthetic rubber, synthetic fibers and plastics, detergents, paints, pesticides, resins and medicines.
