成品油管道枢纽站罐容计算方法研究

Calculation Method of the Tank Capacity for the Junction Station of the Products Pipeline

目前国内成品油管道枢纽站的罐容还没有明确的计算方法,大多参照GB50253《输油管道工程设计规范》中的相关规定进行确定,计算的罐容往往过大,建设用地多,造成工程投资偏高。以兰郑长成品油管道咸阳油库为例,通过对咸阳油库各种运行工况的分析,引用流量差的概念,阐述了一种成品油管道枢纽站罐容计算方法。并和参照《输油管道工程设计规范》罐容计算结果进行了经济对比。对比结果表明:阐述的罐容计算方法经济适用,可用于今后类似成品油管道枢纽站罐容的确定。

At present,no clear calculation method has been created for the tank capacity at the junction station of the products pipeline.The tank capacity determination usually consults with the relevant provisions of＂Code for design for oil transportation pipeline engineering＂（GB50253）,but the calculated tank capacity is usually too large,the acreage is more and the project investment is high.The paper takes the Xianyang tank farm on the Lan-Zheng-Chang products pipeline as an example by analyzing various operation conditions in the Xianyang tank farm and utilizing the＂Differential Flow＂concept to expound a tank capacity calculation method for the products pipeline.The expenses are compared.The results of the comparison prove that the calculation method of the tank capacity is economical and reasonable,and this method can be used to calculate the tank capacity for projects with conditions similar to the project mentioned above.
