介绍了某炼厂溶剂再生装置的工艺流程、再生机理，探讨了溶剂再生装置运行中存在闪蒸罐温度难以控制、B系列富液夹带杂质等问题。建议采用增加贫富液换热二级换热器的方式，提高闪蒸温度及可控性，进一步脱除富胺液中的溶解烃。加氢裂化装置送来的富胺液中夹带杂质，可通过增加过滤器的方式进行消除，确保胺液再生系统平稳生产。采用Aspen Plus软件建立溶剂再生装置模型，对闪蒸温度进行模拟分析，发现A、B富胺液闪蒸温度控制在60~65℃有利于脱除富胺液中的烃类，烃类闪蒸率均超70%。对A、B系列溶剂再生塔塔顶压力与塔顶回流量进行优化，进一步降低蒸汽能耗，为装置高质量运行提供理论支撑。

The process flow and regeneration mechanism of the solvent regeneration unit in a refinery are introduced.The existing problems during the operation of the unit are analyzed,such as the difficulty in controlling the temperature of the flash tank and the entrainment of impurities in the B series rich liquid.It is proposed to add a secondary heat exchanger for heat exchange between lean and rich liquid in order to increase the flashing temperature and its controllability,and further remove the dissolved hydrocarbons in the rich amine liquid.The entrained impurities in the rich amine solution sent from the hydrocracking unit can be eliminated by adding a filter to ensure the stable production of amine solution regeneration system.Aspen Plus software is utilized to build a model for the solvent regeneration unit.It is shown through a simulation analysis on flashing temperature that the flashing temperature of A and B rich amine liquids should be controlled at 60-65℃,which is beneficial to the removal of hydrocarbons in the rich amine liquid,and causes the flashing rate of hydrocarbons to exceed 70%.The pressure and reflux at the top of the A series and B series solvent regeneration towers are respectively optimized to further reduce steam energy consumption and provide a theoretical support for the high-quality operation of the unit.
