Research on Infrared Thermal Imaging Technique for the Sidewall of LNG Storage Tank

Abstract:

Liquefied natural gas (LNG) is obtained by cooling the gas temperature to -162 degree. Problems with the steel cans, the insulation layer or the concrete tank of the LNG tank can lead to changes of the temperature, local temperature decreases, and the safety of the tank is threatening. Through the combination of many sets of infrared thermal imager to monitor the temperature of the LNG storage tank’s sidewall, analyze the heat imagine, establish the corresponding relationship between the locations on the sidewall of the LNG tank and on the heat imagine, determine the position of the temperature point on the tank wall. Infrared thermal imaging technique for the sidewall of LNG storage tank can find out the heat abnormal conditions and fixing the temperature drop area in time, and provide powerful guarantee for the safe storage of the liquefied natural gas.
