摘要
对于成品油长输管道而言,保证油品质量、减少混油,并将油品安全输送至下游油库尤为重要,目前国内在成品油管道-35#柴油/97#汽油的混油切割作业中尚无成熟经验。以吉长成品油管道-35#柴油/97#汽油的混油切割为例,结合实际运行数据,分析输送期间不同输量对混油量的影响,结果表明:吉长成品油管道以400 m3/h的输量运行,可以最大限度地减少混油量。明确了混油切割计算中密度的选取依据,提出了非对称切割方法。通过分析管道沿线各检测点混油量的变化趋势,得出混油增长经验公式,即长春末站的混油量约为吉林首站初始混油量的1.15倍(或8#阀室混油量的1.02倍),并且总结提出指导-35#柴油/97#汽油混油切割作业的建议,保障了管道运行安全,提高了经济效益。
For long-distance product pipelines, it is of great significance to ensure the product quality, reduce contaminated volume and transport the product to the downstream tank farms safely. However, there is no mature experience at home for cutting the contaminated product of -35# diesel/97# gasoline in product pipelines. In this paper, the contaminated product cut of -35# diesel/97# gasoline in Jichang Product Pipeline was taken as an example. The effects of transportation rate on contaminated volume during the transportation were analyzed based on its actual operation data. It is indicated that when the Jichang Product Pipeline is operated at the transportation rate of 400 m3/h, the contaminated volume can be reduced to the utmost. The selection basis of density for the calculation of contaminated product cut was defined, and the asymmetric cut method was proposed. The empirical formula of contaminated product growth was established by analyzing the change trend of contaminated volume at each detection point along the pipeline. Based on this empirical formula, the contaminated volume at Changchtm terminal can be predicted, and it is 1.15 times the contaminated volume at Jilin Initial station （or 1.02 times the contaminated volume at 8# valve chamber）. Finally, some suggestions were recommended to guide the contaminated product cut of -35#diesel/97# gasoline which are conducive to ensuring the safe operation of pipelines and improving the economic benefits. （5 Figures, 1 Table, 23 References）
