水力旋流器应用于渣油高温液固分离

利用水力旋流器对渣油进行高温液固分离，研究了高温工况下渣油的物理性质和石油化学成分对分离性能的影响. 结果表明，水力旋流器在高温下对渣油中的重组分颗粒有显著的分离效果，分离后产物的密度和粘度发生了明显变化，当渣油加热到200℃、入口流量为15 m3/h时，对甲苯不溶物、沥青质、胶质的分离效率最高，分别达53.6%, 47.1%和30.7%，促进了颗粒、大分子的缔合、团聚作用. 根据平衡轨道理论计算了水力旋流器的切割粒径d50，与实验结果基本相符.

Separation of Solid from Petroleum Residue with a Hydrocyclone at High Temperature

Separation of solid from petroleum residue was carried out with a hydrocyclone at high temperature. And the influence on the separation efficiency of hydrocyclone was studied owing to the physical property and the petroleum chemical ingredient of the residue. The experimental results show that hygrocyclone can separate high-density particles in the residue effectively. And the density and viscosity of the flows before and after separation vary greatly. The separating efficiencies of toluene insoluble components, asphaltene and resin reach to 53.6%, 47.1% and 30.7% respectively under the temperature of 200℃ and the flow rate of 15 m3/h, which is mainly due to the combination and reuniting among particles and macromolecules. Moreover, calculation on cutting diameter was made according to the equilibrium orbit theory and testified to be consistent with the result of experiments.
