Analysis of Calculation and Testing Methods for Evaporation Rate of Large LNG Storage Tank
Daily evaporation rate is a key indicator for evaluating the cold insulation performance of LNG storage tanks.Studying the calculation and debugging technology of tank evaporation rate is beneficial for the safe and stable operation and maintenance of LNG storage tanks.By studying the structure of LNG full capacity storage tanks,calculation and analysis were conducted on the heat leakage from the tank top,tank wall and tank bottom.At the same time,the influence of solar radiation temperature rise on the evaporation rate of the tank was considered,and a calculation method for the evaporation rate of the tank was provided.At the same time,combined with the tank evaporation rate testing method,the calculation method was reviewed and verified through the actual project tank evaporation rate testing.
