摘要
含蜡原油输送过程中添加降凝剂可有效的改善原油的流动性,是保证原油安全、经济输送的重要技术手段之一,新型高效降凝剂的研制开发一直是石油储运工作者研究的重点。通过对国内外原油降凝剂的考察研究,阐述了原油降凝剂的种类、作用机理及影响降凝效果的因素,介绍了降凝剂发展的一个重要方向——降凝剂的复配使用,认为降凝剂的复配使用对于新型降凝剂的研制具有重要的意义。同时对原油降凝剂的作用效果做出了评价,并结合降凝剂在我国长输管道中的应用实例,指出降凝剂开发过程中的难点及今后研究的方向。
Pour point depressant added in the process of waxy crude oil transmission can effectively improve the fluidity, which is one of the important technical means to assure the safety and economy. The develop- ment of a high efficiency pour point depressant has been the focus in the study for oil storage and transpor- tation workers. Based on the investigation of oil pour point depressant at home and abroad, this paper ex- pounds the types and mechanism and the main influencing factors of the pour point depressant. An impor- tant development direction of the additives about compound use were reviewed. Using complex additives has important implications for the development of new additives. Then, the effect of pour point depressant is evaluated. In addition, some problems and research directions of depressant used in our long-distance pipeline is discussed.
