摘要
焦化反应温度、焦炭塔操作压力、循环比是影响延迟焦化过程的主要因素,通过分析,提出了改善产品分布、增加液体产品收率的技术方案和以增加装置处理能力为目的技术改造方案。选择合适的工艺流程和改造方案,以最小的投入,荻取最大的效益。
Reaction temperature,operating pressure inside coke drum and recirculation ratio are the main factors influ- encing delayed coking process.Based on the analysis,the technical proposal for improving product distribution and in- creasing liquid product yield is put forward,and the techni- cal innovation proposal which aims for a higher processing capacity of the unit is also advanced.By selecting an ap- propriate process flow scheme and innovation proposal, maximum benefit can be achieved at minimum cost.
