摘　　要：在成品油管道顺序输送过程中,当环境温度较低时,柴油可能形成蜡沉积物,污染后行汽油,造成混油损失。开展柴油蜡沉积研究,对保障成品油管道经济高效运行具有重要意义。对此,总结了现有的主要蜡沉积理论;从静态实验和动态实验两个方面梳理了柴油蜡沉积实验研究现状;分析了基于分子扩散和剪切弥散两种理论建立的柴油蜡沉积速率预测模型。指出加强对柴油结蜡机理的研究,建立柴油蜡沉积模型,定量表征后行汽油溶蜡后主要质量参数的变化规律,是成品油管道顺序输送的重要研究方向。通过对柴油蜡沉积研究进展的系统阐述,为将来深入开展相关研究提供了重要参考。(图1,参29)The wax deposits of diesel may be formed at low environment temperature during the batch transportation of products pipeline, which will contaminate the subsequent gasoline, resulting in the loss of oil mixing. Therefore, researches on wax deposition of diesel are significant to ensure the economic and efficient operation of products pipelines. Herein,the existing theories on wax deposition were reviewed, and the status of experimental study on wax deposition of diesel was clarified from perspectives of static and dynamic experiments. In addition, the prediction models of wax deposition rate of diesel based on the theories of molecular diffusion and shear dispersion were summarized. Thereby, it is pointed out that strengthening the research on wax deposition mechanism, establishing wax deposition model, and quantitatively characterizing the change rules of quality parameters of the subsequent gasoline with the wax dissolved, are the key direction of research on batch transportation of products pipeline. Besides, by systematically representing the progress of researches on wax deposition of diesel, some reference is provided for the relevant deep researches that may be performed in the future.(1 Figure, 29 References)
