摘要

A new process of catalyst particles separations based on hydrocyclone technology is designed and an industrial sidetrack tester was set up in an 1.8 Mt/a catalytic cracking unit. In order to improve the separation efficiency of catalyst par-ticles from oil slurry by hydrocyclones, the computational fluid dynamics method was used to optimize the geometry design of the hydrocyclone. Based on the simulation, a new design is proposed and proves to be able to improve the performance of hydrocyclone considerably. The catalyst solid particles concentrations in the range of 7,080-12,210 mg/L can be reduced to the range of 1,520-5,660 mg/L by the hydrocyclone. The method of hydrocyclone separation is feasible to remove catalyst particles from oil slurry.
