In the light of delayed coke operation in Petrochina Jinzhou Petrochemical Company,and in consideration of the major factors affecting the longterm operation of the coke,the purpose of reducing coking in furnace tubes,coke tower gas pipelines and fractionators were all analyzed.

结合中国石油锦州石化公司延迟焦化装置的实际运行情况，从加热炉、焦炭塔大瓦斯管线和分馏塔结焦方面，分析了制约延迟焦化装置长周期运行的主要因素，在此基础上，给出了该装置为延长运转周期所采取的一些措施，并提出了改进建议。

An injection rate of 15μg/g CDF-10 antifoaming agent was normally injected to the top of the coke drum at the final 2-6 h of the coking cycle. It could eliminate 3m foam and increase the effective utilization ratio of the coke drum from 65%to 78%, and resulted in higher throughput. The said antifoaming agent had no poison effect on hydrogenation catalyst.

应用结果表明， CDF-10消泡剂一般于生焦周期的最后2～6 h，以15 μg/g 的量在焦化塔顶注入可以将焦炭塔内泡沫层消除3 m，使焦炭塔的有效利用率由65%提高到78%，处理量也可相应提高，并且不会造成对加氢催化剂的硅中毒。

The simulation results show good agreement with the industrial process mechanism. In order to describe the oil trap structure of the main fractionating tower, the basic tray model is improved by embedding oil trap model.

还针对燕化延迟焦化装置分馏塔中存在的集油器结构的特点，对分馏塔的基本塔段模型进行改进得到了含集油器结构的塔段模型。

This paper regards Coke Tower delayed coking workshop of JINXI PETRO AND CHEMICAL COMPANY as the research object and accomplished the following content:(1) Checked the age degree and mechanical properties of the Coke Tower and analyzed the metallographic organization and mechanical properties of the coking drum and weld line obtained by checking.

The delayed cooking equipment process mainly consists of heating furnace, coke drum, fractionating tower and some other simple units. Since the heating, coking and fractionating are focused on this study, heating furnace, coke drum and fractionating tower are established and the suitable solution way is selected.

延迟焦化装置流程主要包括加热炉、焦炭塔、分馏塔和其他一些简单单元设备，本论文分别对加热、焦化、分馏过程进行研究，建立了加热炉、焦炭塔、分馏塔模型并选择适宜的解法。

Optimization of coke height control index of coker tower,decrease of circulating ratio ,revamp for perfection of the plant,and shortening coke formation period of coker tower,etc.

介绍中国石化镇海炼化分公司Ⅱ焦化装置投产后，通过采取一系列优化装置运行水平的措施：优化焦炭塔焦高控制指标、降低循环比、对装置进行完善改造、缩短焦炭塔生焦周期等，使装置处理量由设计值125 t/h提高至152t/h，能耗由设计值28.67 kg/t下降至23.2 kg/t左右，装置运行水平明显提高。
