液—液旋流分离技术综述

在对国内外技术文献广泛调研分析的基础上，结合近年来的研究实际，简要回顾了液—液旋流分离技术的发展历程，并从静态旋流器、动态旋流器、低剪切增压技术和系统工艺设计四个方面，较为全面地论述了液—液旋流分离技术的发展概况。分析认为静态旋流器的应用主要在于含油污水处理和高含水原油的预分离对低含水原油的旋流脱水净化，由于介质粘度大，会导致静态旋流器中压降和能耗的成倍增加，因此，相比之下动态旋流器有可能成为更可行的替代方案。同时介绍了国外在低剪切增压和系统流程设计方面的最新成果，据此提出了“九五”

As the latest high grade technology developed in the middle of 1980s,liquid liquid hydrocyclones occupy a very important place in the oil surface engineering.Now the applications of the technology in our oil industry will be one of the significant scientific and technological projects of CNPC(China National Petroleum Corporation) in the Ninth Five Year Plan.On the basis of combining our research works made in recent years with the extensive analysis of internal and external references,the development of liquid liquid hydrocyclones and the related technologies are comprehensively reviewed in this paper.Finally,in order to promote the realization of the project in the Ninth Five Year Period,some suggestions are put forward.
