摘要:
大型常压LNG 储罐是LNG 接收站中非常重要的单元设备，其冷却过程是LNG 接收站试运
投产过程中风险最大、最难控制的一个环节。详细介绍了LNG 接收站试运投产过程中LNG 储罐
的冷却过程，冷却前提条件及注意事项。分析讨论了LNG 储罐冷却过程中储罐温度变化趋势、冷
却喷淋流量、冷却速率及温度监测点最大温差等技术参数之间的相互联系。指出冷却过程容易出现
管道变形受阻，管道法兰连接处泄漏，冷却流量控制不均造成储罐温降不均，以及火炬系统易产生积
液等问题，给出相应的解决方法。研究成果可为其他LNG 接收站试运投产过程中LNG 储罐的冷
却提供参考。（图6，参5）
Abstract:
The large-scale atmospheric LNG tank is a very important unit equipment in LNG terminal, and its cooling
process is the highest risk link and is the most difficult to be controlled in the commissioning and test run process of LNG
terminal. In this paper, the cooling process preconditions and precautions of LNG storage tanks in the commissioning and
test run process of LNG terminals are introduced in detail, and the relations between technical parameters in the cooling
process, such as temperature trend, the trial operation of the LNG terminal, tank temperature trends, spray cooling flow rate,
cooling rate and maximum temperature difference in monitoring point in LNG storage tank during the cooling process are
analyzed and discussed. It is pointed out that in the cooling process the problems such as pipeline’s deformation to blockage,
leaking at pipe flange connection, uneven temperature decrease of the storage tank due to uneven cooling rate control, and
liquid accumulation in flare system, etc. will easily occur. Relative measures against these problems are given. The research
results can provide a reference to the cooling of LNG storage tank in the commissioning and test run process of other LNG
terminals. (6 Figures, 5 References)
