As a professional service provider specializing in low-temperature gas equipment, we have interacted with numerous clients regarding the practical application value of LNG storage tanks. Many people only know that it is a “special container” used for storing liquefied natural gas, but they are not aware of the irreplaceable core role it plays in the entire energy supply chain. Today, starting from the actual implementation scenarios, we will thoroughly explain the real uses of LNG storage tanks and help users from different industries find suitable usage plans for themselves.
The most fundamental and core function is the safe storage of ultra-low temperature media. LNG must remain in a liquid state at -162℃. Our storage tanks adopt a double-layer vacuum insulation design. The inner layer uses special alloy steel resistant to low temperatures, and the outer layer is filled with insulation materials such as expanded perlite. The daily evaporation rate during operation can be controlled within 0.1%. Even when left undisturbed for a long time, it can minimize the loss of the medium to the greatest extent, fully meeting the strict inspection standards of domestic pressure vessels.
In the urban energy system, it acts as an “invisible buffer station” that ensures stable gas supply. During winter heating and peak gas usage periods, the instantaneous gas consumption in the pipeline will be several times higher than usual. Large LNG storage tanks can store sufficient liquid natural gas in advance and convert it into gaseous form through gasification devices to replenish the pipeline. A 100,000 cubic meter storage tank can meet the gas demand of 200,000 households for a single day. In case of sudden pipeline maintenance or temporary interruption of external gas sources, the stored gas in the tank can serve as an emergency fallback, preventing large-scale gas supply disruptions that would affect residents’ lives and commercial operations.
In addition to the regular urban gas supply, it can also break through the coverage limitations of the natural gas pipeline network. In remote mining areas, island sites, or newly-built industrial parks in suburban areas, through the mode of small LNG storage tanks combined with tanker transportation, an independent gas supply system can be established, allowing these areas to also have access to clean and efficient natural gas without waiting for the long pipeline laying period. In the transportation field, the LNG vehicle-mounted storage tanks, with their high vacuum insulation structure, enable heavy trucks and intercity buses to achieve a long-distance range of 600 to 800 kilometers. Compared to traditional fuel, it not only reduces the operating noise by more than 30%, but also completely eliminates the emissions of sulfur dioxide and lead in the exhaust gas.
What many people don’t know is that the ultra-low temperature property of LNG storage tanks can also bring about cross-border value. During the gasification process of the liquid natural gas in the storage tanks, a large amount of cold energy is released. This cold energy can be recycled and utilized in scenarios such as cold chain logistics and industrial low-temperature cooling, further improving the efficiency of energy comprehensive utilization.
