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-scale full-containment LNG storage tanks are extensively deployed in LNG terminals in China. This kind of storage tank contains two layers, inner tank (Ni9 steel) and outer tank (reinforced concrete), between which coldinsulating materials is filled. Such storage tanks need complex technologies for commissioning. Particularly, cooling is the most difficult-to-control factor with highest risks. Taking the whole cooling process of 3^# storage tank in Dalian LNG Terminal as an example, detailed description is made for the large-scale full-containment LNG storage tanks. In addition, relevant analyses and discussions are made by using the data. The paper summarizes experiences related to cooling and commissioning of large-scale LNG storage tanks, which may provide some guidance for improving and optimizing cooling and commissioning of LNG storage tanks.
