摘　　要：针对中国石化扬子石油化工有限公司二套延迟焦化装置(以下简称扬子石化二套焦化装置)出现的弹丸焦问题进行了系统的原因分析。通过对装置运行状况的深入分析,并结合大量历史数据的研究,揭示了弹丸焦的形成机理。结果表明:渣油在加热炉出口至进焦炭塔过程中的温差变化情况能够指示该段管线中渣油裂解与缩合反应的剧烈程度。利用温差变化趋势的分析,可以预测并及时调整操作参数,从而有效预防弹丸焦的产生。The causes of the shot coke problem in the second delayed coking unit of Sinopec Yangzi Petrochemical Co.,LTD.(hereinafter referred to as the second coking unit of Yangzi Petrochemical)were systematically analyzed.The formation mechanism of the shot coke was revealed through deep analysis of the operating situation of the device and the study of large amount of historical data.The results showed that the temperature difference change of residuum from the outlet of heating furnace to the inlet of coke tower could indicate the cracking and condensation reaction intensity of residuum in this section of pipeline.Using the analysis on the change trend of temperature difference,the operation parameters could be predicted and adjusted in time,so as to effectively prevent the generation of shot coke.
