浅析延迟焦化装置分馏塔底结焦原因及措施

摘要

The delayed coking plant is an important key convent residual oil in oil refinery which is constitute of furnace, coke tower and dephlegmation tower. The dephlegmation tower is the most important device in delayed coking plant that condensing and gasifying high temperature oil gas comes from coke tower. The wax oil, diesel oil, gas and rich gas were fractionated from sidetrack and top. The coking in fractionating column bottom is the main brake to operate safely, steady, full load, long term for delayed coking unit.%延迟焦化装置是炼油行业中渣油转化的重要手段,延迟焦化装置主要由加热炉、焦炭塔、分馏塔等主要设备组成,其中分馏塔的作用是将焦炭塔反应来的高温油气进行多次冷凝和气化,分别从侧线及顶部馏出蜡油、柴油、汽油、富气等产品,是延迟焦化装置非常关键的生产设备.分馏塔底易结焦一直是制约延迟焦化装置安全、平稳、满负荷、长周期运行的主要因素.
