LNG动力船舶储罐稳压过程

Pressure Regulation Process of LNG Tanks on LNG Power Ships

为研究LNG动力船舶储罐的稳压供液过程,首先对整个增压及稳压过程中参数的变化情况进行分析计算,得到增压及稳压过程中储罐内压力和气液温度随时间的变化曲线。随后,对比分析环境温度、初始液位以及不同供液率对增压速度的影响。最后,分析连续稳压过程中增压速度加快的原因。

The parameter variations of LNG tanks in the whole self pressurization and constant pressure gas-supply process is calculated and analyzed,and the curves of tank pressure vs gas/water temperature in the process are given.The effects of ambient temperature,initial liquid level,and gas-supply rate to the pressurization process are compared and analyzed.The reason why the pressurization speeds up in continuous pressurization process is studied.
