First of all; LNG application technology has been more than 100 years old in the world, so the technology from production, transportation, storage, etc. is very mature, especially in Japan, 90% of its national gas supply is done by LNG, and its LNG is imported. In order to ensure a huge amount of transportation, it has developed into a large-scale LNG storage transport ship, which is received at the port receiving station and then sent to thousands of households for use. The equipment and technology of the whole process are very mature. Although China's development of LNG is late, it is fast. Now there are nearly 80 LNG production plants built and under construction in China, and the annual output exceeds 100 billion cubic meters. Therefore, a mature industrial chain from technology, technology and equipment has been formed. The focus of Yalong Gas Reconstruction Project is on the application side of LNG. As long as the storage, vaporization, pressure regulation, measurement and other links are solved, these equipments are extremely mature and common in China, so we only need to Purchase the relevant parts and connect them with pipes to complete the use of the technology. All purchased parts have formal manufacturers and production licenses, and the technology is very mature. Secondly; in terms of safety, the critical temperature between LNG gas and liquid is -162 ° C, the ignition point is 650 ° C, the explosion range: the upper limit is 15%, the lower limit is 5%, which shows that the danger of LNG mainly comes to the explosion and freezing Two aspects. By comparison, the ignition point of diesel is 220 ° C, the ignition point of gasoline is 427 ° C, and the ignition point of LNG is higher and safer. The range of diesel explosion: 0.6% of the lower limit and 7.5% of the upper limit (from the "Hazardous Chemical Safety Technology Book"), which shows that LNG is more extensive in terms of explosion range than diesel, and it is safer; and in terms of leakage or volatilization Natural gas accidents occur in general residents' homes. Most of them are leaks. The residents' indoors are a basically closed space. The leaked natural gas is nowhere to be distributed. Accidents are likely to occur after being concentrated in the explosion range. However, in this project, LNG is applied to the mixing building. The working environment is empty and mountainous. Even if there is a small amount of evaporation, since the density of natural gas is much smaller than that of air, it will be released at a speed and will not form an explosion concentration. The application of the company's gas conversion project LNG is very safe. At the same time, the pressure regulating station is installed with “double insurance†to ensure safe use of gas. The pressure regulating station is equipped with a gas leakage monitoring alarm device and is linked with the emergency shut-off valve. When the detection point of the gas alarm detects that there is a flammable gas, the emergency shut-off valve is activated immediately, and the emergency shut-off valve is immediately activated to cut off the airflow in the pipeline for protection. When the source of the combustible gas is found and processed accordingly, it can be reset. Emergency shut-off valve. In order to accurately grasp the working conditions of the whole set of pressure regulating stations, it is convenient to monitor and manage the operation of the whole system, and set up the local and external pressure and temperature local display and signal remote transmission, pressure recording and overrun. After the first, second and third stage pressure regulating devices, the first, second and third stage overpressure relief valves are respectively set. When the gas pressure in the pipeline exceeds the preset value of the safety relief valve, the safety relief valve The discharge is automatically turned on, so that the pipeline and gas equipment are always working within the set pressure range, and “double insurance†is implemented to ensure safe use of gas. Third; regarding freezing safety, LNG is stored in a low temperature (-162 °C) environment, the temperature is very low, but the LNG is transported from the factory to the final use, and the whole process is transported in a closed space or pipeline. The middle operator is only the action of the switch valve. There is no direct contact with the LNG liquid. Together with Yalong's training and equipment protection for the operator, the LNG application of the Yalong Gas Reconstruction Project is very safe.
