本文对洛阳石油化工总厂重油催化裂化分馏塔结盐问题进行了剖析。认为催化裂化原料中的氯化物在反应条件下水解生成ＨＣｌ，井与原料中的氮化物反应生成的ＮＨ３进行反应生成ＮＨ４Ｃｌ，ＮＨ４Ｃｌ在分馏塔上部低温部位结晶溶解于水相中形成半流体而堵塞降液管，造成冲塔打乱正常生产。原油中有机氯的存在加剧了分馏塔的结盐速度。在解决结盐问题上，总结了不停工进行分馏塔洗塔的措施；并成功地实现了重油电脱盐工业化，使常压重油含盐量成倍减少。通过这些措施的实施，基本上解决了这一生产难题，并使结盐周期显著延长。
In this paper, Luoyang Petrochemical Plant heavy oil catalytic cracking fractionation tower salt analysis. It is considered that the chloride in the raw material of catalytic cracking is hydrolyzed under the reaction conditions to generate HCl, and the well reacts with the NH3 produced by the reaction of the nitride in the raw material to produce NH4Cl. The NH4Cl crystallizes and dissolves in the aqueous phase at the lower part of the upper part of the fractionation tower to form a semi- Downcomer, causing the tower to disrupt normal production. The presence of organochlorines in crude oils exacerbates the rate of salt formation in the fractionator. In solving the problem of salt formation, the paper summarizes the measures to stop tower washing tower fractionally. The industrialization of heavy oil electric desalination has been successfully realized, and the salinity of heavy oil is doubled. Through the implementation of these measures, this production problem has basically been solved and the salt cycle has been significantly prolonged.
