摘要
针对催化裂化装置油浆换热器存在的积垢和结焦问题,中国石油大港石化公司将超声波在线除垢技术应用于油浆换热器,考察了该技术对换热器换热系数、油浆系统运行以及产品质量和收率的影响。结果表明,应用超声波在线除垢技术后,油浆换热器的传热系数增加26.885 W/(m2.℃),汽包发汽量增加0.404 t/h,油浆换热器的运行周期从5个月延长至8个月,分馏塔塔底油浆系统的运行状况得到改善。
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/（m^2·℃）,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.
