摘要
液化天然气(简称LNG)作为清洁能源得到广泛应用。LNG储罐作为储存的重要设备,其大型化是LNG行业的发展趋势。LNG储罐保冷结构复杂,罐顶、罐壁及罐底保冷各具特点。温度场计算是罐体设计的重要组成部分。对大型LNG储罐进行参数化建模,实现参数化的载荷条件输入,可极大提高设计效率。文章介绍了参数化建模方法,并借助该方法,研究了LNG储罐运行过程中异常工况下的温度场和保冷效果。参数化设计不仅可以帮助工程技术人员优化保冷结构的设计,还能提高分析计算效率,是未来储罐设计的趋势。
Being a kind of clean energy,liquefied natural gas(LNG)has been widely used.As important storage equipment,LNG storage tanks are becoming large in size,which is the development trend of the LNG industry.The insulation structure of LNG storage tanks is complicated,and the insulation characteristics of tank top,tank wall and tank bottom are different.Temperature field calculation is an important part of tank design.The parameterized modeling of large LNG storage tank was performed to achieve parameterized load condition input,which can improve the design efficiency greatly.This paper introduced the method for parameterized modeling.By adopting this method,it researched the temperature field and the effect of cold insulation under abnormal operation conditions of LNG storage tanks.Parameterized design can not only help engineers improve the cold insulation structure,but also improve the efficiency of analysis and calculation.It is the trend of tank design in the future.
