Abstract

Because LNG has the advantages of high calorific value, low pollution and low price, this clean, high-quality fuel has attracted more and more attention from all walks of life. In recent years, LNG technology has developed rapidly, and the scale of installations has gradually increased, and a complete system project for LNG production and storage has been formed. The safe storage of LNG is vital to the development of the industry. The evaporation of LNG in the tank caused by the inflow of environmental heat is an important cause of overpressure and stratification and rollover in the tank, and affects the safe operation of the storage tank. Therefore, it is necessary to study the daily evaporation rate of the LNG storage tank and its influencing factors. Through the analysis of the cooling structure and heat exchange process of LNG storage tanks, a calculation method for heat leakage and daily evaporation rate of large LNG storage tanks is given, and the influence of solar radiation on the heat leakage of storage tanks is comprehensively considered. Taking a 30,000 cubic meter LNG storage tank as an example, the daily evaporation rate and influencing factors are calculated and analyzed. The results show that: (1) Daily evaporation rate of the LNG storage tank meets the relevant national design requirements. (2) The environmental temperature and full rate has a greater impact on the daily evaporation rate, and the environmental wind speed has a small impact on the daily evaporation rate. The calculation of the daily evaporation rate of the LNG storage tank and the analysis of influencing factors can provide a theoretical basis for the cold storage design and safe operation of the storage tank.
