Study on Transportation Technology and Device with Heat Boundary Layer for High Viscosity Oil

The high viscosity oil is of high freezing point,so it is of bigger hydraulic resistance for pipeline transportation.The high viscosity oil can be transported,received,provided and barrel filled in pipeline when it is heated for reducing the viscosity.The disadvantages of steam heating for high viscosity oil is analyzed,the transportation theory of heat boundary layer and technology of high viscosity oil is researched,and the transportation theory of heat boundary layer and its application are exploited.The viscous liquid transportation device is developed based on the heat boundary layer theory.The mathematic model is set up for calculating the hydraulic resistance and the heat loss of the heat boundary layer.According to the computing program,the hydraulic resistance and the heat loss of the heat boundary layer are conformed to the coupling calculation.Therefore,the new technology and new technique can be put into application for pipeline transporting,receiving,providing and barrel filling of high viscosity oil,in which the high viscosity oil is unnecessary to wholy heat for reduce the viscosity.The result has been applied widely,which is of good military,economic and social meanings.
