通过对溶剂再生塔开工过程中出现问题的探究,给出了芳烃抽提装置再生塔开工运行常见问题的分析方法,同时给出了判断贫溶剂汽提水换热器出现内漏的判断依据,并指出了再生塔运行对改善溶剂质量、从而减缓溶剂系统管线腐蚀的重要性,以及如何降低溶剂的降解速度、提高装置的运行周期。 By analyzing the problems occurred in the process of solvent regeneration tower, the analytical methods of common problems in the operation of regeneration tower of aromatics extraction unit are given, and the judgment basis for judging the internal leakage of lean solvent stripper heat exchanger is given. The importance of regenerator operation to improve the quality of solvent and thus the corrosion of solvent system pipeline was also pointed out. And how to reduce the degradation rate of solvent and improve the operating cycle of the system were pointed out.
