摘　　要：分析了国内外7种延迟焦化密闭除焦技术工艺流程和主要特点,国外延迟焦化密闭除焦技术发展较早,早在20世纪60年代已有工程应用,国内延迟焦化密闭除焦技术在2015年由中石化牵头开发并应用工程,综合来看,罐式密闭除焦脱水技术适合新建项目,箱式板链输送机密闭除焦脱水技术由于改造少、投资低,适合改造传统除焦装置。Both process flow and main characteristics of seven closed decoking technologies for the delayed coking at home and abroad were analyzed.This closed decoking technology abroad developed earlier and it had been applied in engineering as early as the 1960s while the domestic ones were developed and had been applied by Sinopec in 2015.In general,the can-type closed decoking and dehydration technology is suitable for new projects,and the closed decoking and dehydration technology of box-type plate chain conveyor is suitable for transforming traditional decoking devices because of less transformation and low investment.
