Description
Technical Field

Background
Natural gas is a combustible gas in the formation, mainly a mixture of low molecular alkanes, and can be divided into dry natural gas and wet natural gas, wherein the dry gas mainly contains methane, and the wet natural gas contains a large amount of ethane, propane, butane and the like besides methane. Department such as national energy agency's oil and gas department publishes Chinese Natural gas development report (2021), which shows: the natural gas multi-supply system in China is continuously improved, and one net in China is basically formed. The long-distance pipeline is built up by accumulation for 4.6 ten thousand kilometers, and the total mileage of the natural gas pipelines in the country reaches about 11 ten thousand kilometers. However, in areas with underdeveloped economy such as suburban counties, mountainous areas, and rural areas and areas with insufficient pipeline radiation, natural gas with obvious advantages, safety, and cleanness cannot be used for life and work. According to statistics, nearly 6 hundred million people in China still cannot use natural gas at present. However, the gas markets in suburban counties, mountainous areas and rural areas are potential markets of town gas, the energy supply of the areas is an integral part of the whole national energy system, and the supply and consumption of the areas necessarily influence the supply and demand situation of Chinese energy. At present, the key points of city construction gradually shift from urban areas to suburban counties, mountainous areas and rural strategies, and an efficient, safe and economic energy supply system needs to be established. The characteristics that the LNG storage tank is suitable for storage and transportation and is flexible in transportation are exerted, the multi-type combined transportation test point demonstration of the LNG storage tank is promoted, and the gas storage capacity is improved by taking measures. Promote the gas storage facility operation enterprises to perfect the internal management mechanism, and carry out mode innovation and product innovation. The natural gas is utilized for the last kilometer. And carrying out natural gas rural trial. And new modes such as the Internet, the energy intelligent micro-grid and the like are explored, and multi-energy cooperative supply and energy comprehensive cascade utilization are realized. And developing distributed energy application test points and the like by taking LNG as an air source in the area uncovered by the pipe network.
Liquefied Natural Gas (LNG), the main component of which is methane, is known as the cleanest fossil energy on earth. The liquefied natural gas is colorless, tasteless, nontoxic and noncorrosive, the volume of the liquefied natural gas is about 1/625 of the volume of the same amount of gaseous natural gas, and the mass of the liquefied natural gas is only about 45 percent of the same volume of water. The advent of LNG (liquefied natural gas) has enabled significant changes in the energy structure of natural gas. The application scene of the natural gas is changed into the application scene which can be built by the natural gas storage and transportation equipment without depending on pipelines and pipe transmission, and the requirements of more users are met.
The pipeline natural gas is most suitable for areas with large gas consumption and concentrated population distribution. However, in recent years, the pipeline laying cost is increased year by year, the investment is increased, the operation cost is high, and the pipe conveying capacity reaches the upper limit. LNG has the characteristics of high safety, wide application range, strong economy and good convenience, and LNG gas supply can be preferentially considered in areas unsuitable for laying pipelines. At present, most LNG gas supply stations adopt a manual verification method to carry out identity verification on filling vehicles loaded from the beginning, and manual filling operation is needed after verification is passed, so that a large amount of labor cost is required to be invested, the filling efficiency is low, and the market demand cannot be met.
