| Abstract: | This paper analyzes and summarizes the coking in the convection section of the delayed coking furnace in CNOOC Oil & Petrochemicals Co.,Ltd.Huizhou Refinery and the treatment of the coking.Mechanical decoking is adopted to deal with the coking in the convection section.After decoking,FCC oil slurry recycling is stopped and heater branch is put into use in time to feed the second point water injection.Coking in the convection section of the heater is controlled effectively.The paper also puts forward some measures to retard coking in the heater. |
