What are the uses of natural gas?
Natural gas is mainly used for the following purposes:1, natural gas power generation, can alleviate the energy shortage, reduce the proportion of coal-fired power generation, the effective way to reduce environmental pollution, and from the economic perspective, natural gas power generation unit installed capacity required less investment, shorter construction period, lower electricity price, with strong competitiveness.2, natural gas chemical industry, natural gas is the best raw material for the production of nitrogen fertilizer, with less investment, low cost, less pollution, etc.. Natural gas accounts for the proportion of raw materials for nitrogen fertilizer production, with an average of around 80% in the world.3, the city gas industry, especially the living fuel. With the improvement of people's living standard and the enhancement of environmental protection consciousness, the demand for natural gas in most cities has increased obviously. The economic benefits of natural gas as civil fuel are also greater than that of industrial fuel.4, compressed natural gas vehicles, natural gas instead of oil, with low price, less pollution, safety and other advantages.At present, people's environmental awareness, the world demand for clean energy is running high, governments have to convey this trend through legislative process, natural gas has been regarded as one of the most clean energy, coupled with the 1990 Middle East of the Persian Gulf crisis, the United States and major oil consuming countries to deepen the development of alternative energy determination, therefore, in haven't found the real alternative energy, natural gas demand will naturally increase.
Natural gas is stored in underground porous rock, the main component of methane, the proportion of 0.65, lighter than air, with colorless, tasteless, non-toxic characteristics. Natural gas companies are in accordance with the provisions of the government to add odor agent (four thiophene), in order to sniff the user identification.If the concentration of natural gas in the air in the range of 5% to 15%, in case of open flame can occur, the concentration range is the explosion limit of natural gas. The explosion in a short time to produce high pressure, high temperature, its destructive power and risk are great. According to the state of natural gas reserves, it can be divided into three types: structural natural gas, water soluble natural gas and coal gas. The structure of natural gas can be divided into crude oil produced by the wet natural gas, and does not contain liquid components of dry natural gas.
The remains of the natural gas system, which have been deposited underground for a long time, are converted into gas hydrocarbons by the gradual transformation and pyrolysis.
