分馏塔对延迟焦化装置长周期运行的影响

焦化装置长周期生产的关键取决于分馏塔的运行状况.而分馏塔受原料组分、生产条件、操作控制手段的影响较大.文中分析了采用控制掺炼油浆的比例、控制较低的分馏塔底温度、适当控制柴汽比等调节手段,可以有效的延长延迟焦化装置的平稳运行周期.

Influence of fractionating column on long-period operation of Delayed Coking Unit

The key to the long-period production of the Coking Unit depends on the operation status of the fractionating column which is very much influenced by feedstock composition,production condition and operation control measures.This paper analyzed the adjusting measures such as controlling the proportion of the blending slurry oil,controlling the low temperature of the fractionating column bottom,and properly controlling diesel oil/gasoline ratio which can effectively extend the smooth operation period of the D...
