摘　　要：大多数延迟焦化装置加工重质或劣质渣油时,为避免弹丸焦的生成,采取降低炉出口温度和提高循环比等措施,虽能确保安全生产,但降低了装置的经济效益。介绍了延迟焦化装置加工沥青质含量较高的原料时,弹丸焦的形成过程和条件,分析了产出弹丸焦的结果和装置的效益,指出弹丸焦已成为国内目前许多延迟焦化装置安全运行和炼油厂提高效益的最大障碍。在重新审视弹丸焦的基础上,提出了延迟焦化装置实施弹丸焦生产方案,以获取最大液体产品收率的建议和措施:首先要重新认识弹丸焦生产方案的潜在价值;其次要完善对延迟焦化装置及其下游装置的技术改造和设备配置;第三要加强对弹丸焦的利用和销售力度;第四要全面提高管理者和操作人员的素质和技能。Most Delayed Cokers processing heavy and inferior residue feeds adopted measures of lowering heater outlet temperature and increasing recycle ratio to avoid shot coke production for safety operation,thus the economic benefits of Cokers were affected.After study on the shot coke formation and analysis of the economics of delayed coker producing shot coke from processing high-asphaltene feed,it is concluded that shot coke is currently becoming the biggest barrier for delayed cokers in China to run smoothly and for refiners to improve their economic profits.Based on the analysis on issues related with shot coke,the production scheme of shot coke in delayed cokers and recommendations and measures for maximized liquid yield are proposed,such as： reconsideration of potential value of shot coke production,technical revamping of delayed coker and associated down-stream facilities,optimized utilization and strengthened sales of shot coke,improvement of management level of management people and skills of operators.
