Study on Vehicular LNG Tank

The vehicular LNG(Liquefied Natural Gas) tank is a key component in the land transportation of-163°C LNG. The cryo-insulation performance of vehicular tank directly affects the security of LNG transport greatly. Based on a 40m3 vehicular LNG tank, a structural design of the vehicular LNG tank is completed, which includes its body,nozzles,heat-insulating layer,sealing devices,saddles and so on. With the safety requirements of less than 2% LNG evaporation rate, the leakage heat of LNG tank is analyzed completely. Then, a heat-insulating layer outside of LNG tank is completed with thermal design. Finally, with thermal software, the effectiveness of heat-insulating layer is proved.
