Abstract: Ultrasonic online cleaning technique was applied on the slurry oil heat exchanger of FCC unit in PetroChina Dagang Petrochemical Company to solve the fouling and coking problems happened there. The effect of ultrasonic technique on the heat transfer coefficient of heat exchanger, the operation of slurry oil system, product quality and product yields was investigated. Results indicated that by using ultrasonic online cleaning technique the heat transfer coefficient of heat exchanger increased 24.327 W/(m2·℃), the steam production of drum increased 0.404 t/h, the operation period of slurry oil heat exchanger was prolonged from 5-month to 8-month and the total operation status of the slurry oil system at the bottom of fractionation column was improved.
Key words: ultrasonic cleaning, catalytic cracking, slurry oil, coking
