Custom Oxygen Nitrogen Argon Storage Tank Thermal insulation method of enclosure structure of oxygen, nitrogen, argon storage tank in chemical industry In the true powder heat insulation method, the interlayer of the liquid nitrogen storage tank is evacuated and filled with powder (pearl sand), which is common in small liquid nitrogen storage tanks. The production technology of vacuum powder insulated storage tanks is basically the same as that of liquid nitrogen and liquid oxygen storage tanks. Therefore, the manufacturing technology of domestic manufacturers is also very mature. Because the operation and maintenance of liquid nitrogen storage tanks is relatively convenient and flexible, it is currently used more many. Most commonly used in domestic LNG gasification stations are 50m3 and 100m3 cylindrical bimetal vacuum powder liquid nitrogen storage tanks. At present, it can be as large as 200m3, but due to its large volume and difficult transportation, it is generally less used. Vacuum powder insulated storage tanks are also made into spherical, but the spherical tank is usually used in the range of 200-1500m3, and the installation of spherical storage tanks on site is difficult. Positive pressure stacking heat insulation, using heat insulation material, interlayer nitrogen gas, the heat insulation layer is usually thick, widely used in large and medium-sized liquid nitrogen storage tanks and storage tanks. Usually a vertical LNG composite storage tank. High vacuum multilayer insulation. High-vacuum multi-layer winding insulation is used, and it is mostly used for tank trucks. Cylindrical bimetallic vacuum powder liquid nitrogen storage tank commonly used in domestic LNG gasification stations. Considering that the vertical tank saves land, and the vertical tank LNG static pressure head is large, which is beneficial to the operation of the self-supercharger, the vertical bimetal vacuum powder liquid nitrogen storage tank is adopted. The LNG storage capacity of this station is not large, and the cold insulation performance requirements are high, so high vacuum multi-layer wound insulation storage tanks are selected. According to the LNG storage capacity and considering the transportation convenience of skid-mounted equipment, a 50m3 horizontal storage tank is selected for the LNG transfer skid. The liquid nitrogen storage tank is equipped with a level gauge, a differential pressure transmitter, a pressure transmitter, a temperature transmitter, and a pressure gauge to realize the on-site indication and remote control of the LNG level, temperature and pressure in the tank . The top of the tank is equipped with a safety explosion-proof device, and the lower part is equipped with a mezzanine pumping interface and a temperature test port. According to the working pressure of the system and considering the economy, the design pressure of the inner tank of the storage tank is determined to be 1.2MPa, and the design pressure of the outer tank is -0.1MPa.Custom Oxygen Nitrogen Argon Storage Tank website:http://www.tank-madeinchina.com/cryogenic-storage-tank/oxygen-nitrogen-argon-storage-tank/
