Removing Solid Particles in Fluid Catalytic Cracking Slurry by Electrostatic Separation and Their Composition
摘要
Abstract
The electrostatic separation of fluid catalytic cracking slurry(FCCS) from a heavy oil catalytic cracking unit was carried out in a self-made experimental installation. The influences of processing time,temperature,packing diameter,separation stages and electric field intensity on the electrostatic removal efficiency were investigated. The solid particles in FCCS were characterized by means of SEM,EDS and XRD. The experimental results showed that,the electrostatic removal efficiency firstly increased and then stabilized with prolonging the processing time,increased with the temperature rise,increased with the decrease of the packing diameter,and increased and then decreased with the increase of the electric field intensity. Under the appropriate conditions of processing time 25-30 min,temperature 140-160℃,packing diameter 2.0-2.5 mm and electric field intensity 3.5 kV/cm,through three-stage of electrostatic separation,the electrostatic removal efficiency reached 99% and the content of the solid particles in FCCS lowered from 4 200 mg/L to less than 50 mg/L. The solid particles in FCCS consisted of catalyst powder,coke powder and antimony mainly.关键词
