摘　　要：延迟焦化是渣油转化的首选工艺。目前,延迟焦化装置和焦炭塔的发展趋势是装置规模大型化。延迟焦化工艺和设备的发展大大改进了延迟焦化技术,循环时间已由24h缩短到18h;提高了液体收率,减少了焦炭产出率;延长了装置的运行时间。文中介绍了焦炭塔消泡剂、加热炉阻焦剂及先进控制系统的应用情况和效果。The delayed coking technology is a main process for the residuum transform technique. At present,it is necessary to enlarge the scales of delayed coking unit and coke column. The developments of the delayed coking technology and the equipments have improved the delay coking technique enormously. The cycle time is reduced from 24 hours to 18 hours. The liquid output is improved,and the coke yield is lowered. The working time of delayed coking units is prolonged. The applications of antifoaming additive in the coke column,anti-welding agent in heating furnace and the advanced control system are introduced.
