1.20Mt/a延迟焦化装置焦炭塔大油气管线结焦分析

摘要

Coke tower big oil-gas pipeline coking is affected by delayed coking device run period the main factors, the integration of current domestic and foreign delayed coking of coke tower big oil-gas pipeline coking analysis, and according to the specific phenomenon of 1.20 MT / a unit coking petroleum pipeline of coke, it is concluded that the main factors affecting coking feedstock properties, outlet temperature of heating furnace, coke tower top temperature control, quench oil, coke tower gas speed and so on. At the same time, put forward the reasonable control of heating furnace outlet temperature, improve the quench oil properties, reduce the coke tower gas speed slow down measures of coking.%焦炭塔大油气管线结焦是影响延迟焦化装置长周期运行的主要因素,综合当前国内外延迟焦化方面对焦炭塔大油气管线结焦的分析,并根据1.20 Mt/a焦化装置大油气管线结焦的具体现象,得出影响结焦的主要因素有原料性质、加热炉出口温度、焦炭塔顶部温度控制,急冷油、焦炭塔气速等.同时,提出了合理控制加热炉出口温度、改善急冷油性质、降低焦炭塔气速等减缓结焦措施.
