添加剂改性对催化裂化油浆静电分离的影响
The influence of additive modification on electrostatic separation of FCC slurry oil
摘要
Abstract
To improve the electrostatic separation of the catalytic cracking slurry oil,the slurry from the first stage electrostatic separation was modified for further electrostatic separation in the second stage. Comparing electrostatic separation efficiencies after the addition of four kinds of additives,it was found that additive A was the most effective solvent,which had higher permittivity and lower conductivity. Through the optimization of electrostatic separation experiment conditions after adding additives, the optimal experimental conditions of the modified electrostatic separation was determined. The second-stage electrostatic separation efficiency was increased by 21％ compared to the first stage; and the catalyst particles in purified slurry was below 10μg/g. the permittivity of solid particles was measured using Energy spectrum analysis and FTIR. The particle sizes and compositions before and after the electrostatic separation were determined. It was found that added additive A in FCC slurry before electrostatic separation could reduce the particle content and increase the permittivity of purified slurry. The effect to catalyst particles in slurry was more noticeable.关键词
