发布时间：2018-10-25 14:58
【摘要】：大型全包容式LNG储罐是目前国内LNG接收站广泛采用的一种罐型,此类储罐为内外两层,内罐采用Ni9钢,外罐采用钢筋混凝土,中间填充保冷材料,其投用技术比较复杂,而储罐冷却技术是其投用调试过程中风险最大、最难控制的一个环节。结合大连LNG接收站3#储罐冷却的整个流程,对大型全包容式LNG储罐进行了详细的描述,并结合数据进行分析讨论。总结了大型LNG储罐的冷却投用经验,为进一步完善优化LNG储罐冷却投用技术给出了指导性建议。
[Abstract]:Large all-inclusive LNG storage tank is widely used in domestic LNG receiving station at present. This kind of tank is of both inner and outer layers. The inner tank is made of Ni9 steel, the outer tank is reinforced concrete, and the cold insulation material is filled in the middle. The tank cooling technology is one of the most risky and difficult to control during commissioning. Combined with the cooling process of Dalian LNG receiving station, the large all-inclusive LNG storage tank is described in detail, and the data are analyzed and discussed. The experience of cooling operation of large LNG storage tank is summarized, and some guiding suggestions are given for further improvement and optimization of cooling operation technology of LNG storage tank.
