The basic structure of the LNG storage tank is as shown in the figure. The outer piping and operating system are located at the bottom of the tank, while the inner cylinder is used to contain LNG. Various pipelines connected to it extend to the outer piping system through the annular space. The outer cylinder, on one hand, forms a sealed vacuum insulated space with the inner cylinder, and on the other hand, provides protection and support for the inner cylinder. The support between the inner and outer cylinders is made of glass fiber reinforced plastic with excellent insulation properties, used to support the axial and radial loads of the inner cylinder.

When refilling the tank with liquid, open the upper and lower inlet valves, and activate the exhaust pipe system. The liquid enters the tank through the filling port, and the liquid level is read from the level gauge. Stop refilling when liquid starts to flow out of the overflow port. For draining, activate the self-pressurization system, and the tank will maintain pressure while draining, with the liquid exiting through the filling port.
LNG (Liquefied Natural Gas) - the abbreviation for Liquefied Natural Gas in English.
Natural gas is a combustible gas extracted naturally from gas fields, primarily composed of methane.
2, LNG is produced by cooling natural gas to -162℃ at atmospheric pressure, causing it to condense into a liquid.
Liquefied natural gas (LNG) significantly reduces storage and transportation space and costs, and boasts high calorific value and superior performance.

LNG is a clean and efficient energy source.
1. Importing LNG aids energy-consuming countries in diversifying energy supply and ensuring energy security, while exporting LNG benefits natural gas-producing countries by effectively developing natural gas resources, increasing foreign exchange earnings, and promoting national economic development. Consequently, LNG trade is emerging as a new hot spot in the global energy market.
Natural gas, as a clean energy source, is gaining popularity, with many countries listing LNG as an optional fuel. Its proportion in energy supply is rapidly increasing.
Liquefied natural gas is growing at an annual rate of approximately 12%, making it one of the fastest-growing energy sectors globally.
In recent years, global LNG production and trade have become increasingly active, with LNG emerging as a scarce clean resource and becoming a new hot spot in the world's oil and gas industry.
To ensure diversified energy supply and improve the structure of energy consumption, major energy-consuming countries are increasingly focusing on the import of LNG. Japan, South Korea, the United States, and Europe are all constructing LNG receiving terminals on a large scale.
6. Major international oil companies are increasingly shifting their new profit growth focus to LNG operations, with LNG poised to become the next hot global commodity in the energy market after oil.
China's natural gas utilization is extremely unbalanced, and natural gas constitutes a small proportion in China's energy mix.
8. Looking at China's natural gas development situation, natural gas resources are limited, and production is far less than demand, with the supply-demand gap widening.
9. Although it hasn't reached scale yet, the characteristics of LNG determine its rapid development.
10. It is predictable that in the next 10 to 20 years, LNG will become the dominant force in China's natural gas market.
In 2007, China imported 2.91 million tons of LNG, triple the amount of 2006.
In January to December 2008, China's total import of liquefied natural gas was 3,336,405 tons. In January to December 2009, the total import was 5,531,795 tons. Amidst China's continuous and rapid economic growth, there was a severe shortage of energy to power the economy.
Detailed Description of LNG Low-Temperature Storage Tank:
The LNG storage tank is a horizontal double-walled structure, composed of an inner tank, an outer tank, internal and external supports, an insulating layer, a pressure safety system, a vacuum pump, and a pipeline system. All vacuum-insulating structures rely on vacuum. Due to the high degassing rate and suction resistance of the insulating space materials, and the inability to exceed high baking temperatures for the sealing materials, which also degas slowly, suction is challenging. To achieve the required vacuum level within the design-specified suction time, factors include the vacuum pump and suction process, as well as the flow area of the annular suction pipes. To ensure a high vacuum level and improve suction speed, a vacuum pump is installed at both ends of the equipment. One pump consists of three suction pipes, placed in the lower half of the annular space and extending from the bottom, while the other pump, also with three suction pipes, is situated in the upper half of the annular space and extends from the top. The two groups of suction pipes intersect and overlap along the tank's length. By increasing the flow area of the suction pipes and employing various auxiliary methods such as heating and nitrogen displacement, the vacuum achievement time for the annular insulating space of 100 m³ is reduced to one-third of the conventional structure.
