摘要

为研究碱式硫酸铝再生法解吸SO2的最佳工艺条件

考察了加热条件下解吸时间、解吸液初始SO2浓度和解吸温度对SO2解吸过程的影响。实验结果表明

解吸液初始SO2浓度为16~20g/L

解吸温度80℃

解吸60min为最佳的解吸条件

在此条件下

SO2解吸率约为70%;对解吸后的吸收液进行循环脱硫实验

脱硫效果约90%

相比新鲜吸收液略有下降。

Abstract

To search for the optimal technical condition of the regeneration of basic aluminum sulfate used for SO2 desorption

the influence of factors like desorption time

initial SO2 concentration and temperature under heating condition on the SO2 desorption process was studied.The results demonstrate that

the best desorption condition was to maintain the desorption process for 60min with the SO2 initial concentration of 16g/L to 20g/L at 80℃.The SO2 desorption rate under this condition was between 70% and 76%.The desulfurization test on the desorbed solution showed the desulfurization efficiency was about 90%

a little lower than that of the fresh solutions.
