(Summary description)Atmospheric LNG storage tank manufacturers are familiar with the structure and principle of lng cryogenic storage tanks, and carry out LNG operations in strict accordance with the operating instructions. The tanks are equipped with tanked joints that can deliver liquids to vaporizers and tanks. Such welding will give operators Bringing certain dangers, without applying any energy, the liquid or gas can be supplied to the outside to ensure the purity of the discharged liquid or gas. The inner tank and the bottom of the shell are insulated by sandwich pearl sand, the water tank is in working condition, and the storage is dry. The horizontal seismic action of the tank includes the seismic force caused by the weight of the cylinder and the weight of the piston.

Regarding large-scale atmospheric LNG storage tanks, small and medium-sized gasification stations generally use vacuum powder-insulated cryogenic storage tanks. The liquid oxygen from the air separation plant should contain almost no hydrocarbons, but due to long-term use, trace amounts of hydrocarbons may also be in the tanks. Concentration and accumulation may cause accidents under certain conditions. Therefore, in the process of selecting cryogenic storage tank valves, material is an important issue. The domestic standard is based on conversion, which can make part of the gas phase in the inner container absorb at low temperature. Liquefaction, to maintain the relative stability of the gas phase pressure of the inner vessel during filling.
The vacuum tank of the vacuum tank is a double metal tank. The outer tank is made of carbon steel. The insulation material is filled with interlayer and vacuumed. After pressure test at the factory, the vacuum tank is transported to the site as a whole. The total storage capacity of LNG is below 1,000 cubic meters. , The process of the vacuum tank is relatively simple. Generally, a supercharger is used to pressurize into the tank. The material flows into the vaporizer under pressure without using power equipment and has low energy consumption. Therefore, small LNG gasification stations at home and abroad are basically adopted Vacuum tank form.
The large atmospheric LNG storage tank has an operating pressure of 15KPa and an operating temperature of -162 degrees. It is a flat-bottomed double-walled cylindrical tank. The inner tank is used to store liquefied natural gas. The internal, internal and external boxes are designed to be separated and independent, and the tank top is a self-supporting vault, which can withstand the external pressure brought by cold insulation materials and the internal pressure brought by internal gas.
The water tank uses pearl sand as the cold insulation material, filled with dry nitrogen to ensure the slight positive pressure of the sandwich, isolate the heat insulation material from the atmosphere, and prevent the influence of atmospheric pressure or temperature changes and the humid air from entering the cold insulation layer between the inner and outer water tanks. To increase the life of cold insulation materials, so as to maintain the design and manufacture of heat insulation structure, we must pay attention to moisture-proof measures.
