西部成品油管道混油切割新方法

在确保油品质量安全的前提下，持续改进混油切割方法，可以有效降低混油切割量，提高管道运营公司的经济效益。通过总结西部成品油管道实际运行过程中混油段过站时混油量的变化规律，并与沿程混油量的理论变化情况相印证，提出了以末站上游新堡站的混油量为基准增加50m3作为末站混油切割目标量的方法，并应用于实际生产，效果明显。该方法解决了因后行油品密度无法提前准确确定，在计算第2个混油切割点时，经常误差较大，易造成混油切割量偏大或者油品不合格的问题。（图2，参5）

New method of contaminated oil cutting used in Western Product Pipeline

On the premise of assuring the quality of products, constant improvement in contaminated oil cutting method can effectively reduce the volume of contaminaed oil cutting and increase economic benefits of pipeline operation companies. Through analyzing the variation in contaminated oil volume when the contaminated oil passing the stations in the actual operation of the Western Product Pipeline and corroborating with the theoretical variation of contaminated oil volume along the way, the method of adding 50 m3 to the basic volume of contaminated oil of Xinbao Pupm Station which is in the upstream of terminal station to be the target volume of contaminated oil cutting at the terminal station was proposed. This method has been working well in actual operation. When calculating the second cut point, because the density of the following oil can not be predicted accurately in advance, usually the calculation error is large, which may easily lead to issues like the volume of contaminated oil cut is too large or the oil is unqualified, which can be solved by this method. （2 Figures, 5 References）
