摘　　要：研究针对硫磺回收装置的效率问题,通过降低余热锅炉的产汽压力和清洗换热器,提升热能利用效率。对汽提塔的操作条件进行调整,通过更新脱硫溶剂,增强脱硫效果。同时,改进了净化水的循环利用,减少了资源浪费。调整溶液循环量能够有效减少硫化氢和二氧化碳排放量,达到国家环保标准。吸收塔进气压力和温度的变化影响吸收剂循环量,为硫磺回收节能和减排提供了方法。The study focuses on the efficiency of the sulfur recovery unit,optimizing the steam production pressure of the waste heat boiler,cleaning the heat exchanger to improve efficiency,and updating the desulfurization solvent to enhance the desulfurization effect.At the same time,the recycling of purified water is improved and resource waste is reduced.Adjusting the solution circulation volume effectively reduces hydrogen sulfide and carbon dioxide emissions and meets national environmental protection standards.Changes in the inlet pressure and temperature of the absorption tower affect the amount of absorbent circulation,which provides a method for energy saving and emission reduction in sulfur recovery.
