液化石油气作为易挥发介质，在常温下的饱和蒸汽压可以达到1.36 MPa，因此液化石油气在常温下需要储存在压力容器中。为了保证其储存的安全性和流程设计的合理性，结合克石化球罐区设计的具体项目，对液化气球罐在工艺设计中涉及到的重点内容作以详细归纳，例如球罐二次脱水工艺的设计、事故状态下的水顶烃工艺和罐区布置。此外，为保证球罐在事故状态下能够安全泄放，罐顶安全阀的设置尤为重要，将理论计算与实际设计参数相结合，对1000 m3和2000 m3球罐安全阀的的选取进行了详细计算说明，将对液化气球罐的设计具有指导作用。

LPG is a volatile media, whose saturated vapor pressure can be 1.36MPa at normal temperature, so it should be stored in a pressure vessel at normal temperature. In this paper, in order to ensure the safety of its storage and the reasonableness of its process design, combining a specific project of spherical tank design in Karamay Petrochemical Company, the key elements in the process of design were summarized, such as the second dehydration process, water sealing hydrocarbon under the condition of accident and tank arrangement. Besides, in order to guarantee safety relief of the spherical tank,the safety valve setting is very important. At last, how to select the safety valve of 1000m3 and 2000m3 spherical tanks by the mean of combining the theoretical arithmetic with the actual design parameters was introduced.
