Cryogenic liquid nitrogen storage tank
The cold insulation material at the bottom of the lng natural gas liquid nitrogen storage tank and the overall design of the cold insulation not only ensure that the cold loss of the liquid nitrogen storage tank is minimized, but also the tensile strength of the cold insulation material must be able to withstand the inner tank, low temperature liquid Curb weight and liquid phase working pressure. In the design and construction of the 20000m3 cryogenic liquid nitrogen storage tank, the bottom of the liquid nitrogen storage tank is insulated according to the different pressures at each position of the bottom of the liquid nitrogen storage tank and the principle of reducing the cold loss rate to the greatest extent. The structure is divided into two parts, the pressure ring and the ring, and different insulation materials are used.
