摘要
针对裂解装置催化再生尾气焚烧废气经海水脱硫后二氧化硫的监测,利用碘量法和定电位电解法同时测定二氧化硫的浓度,并对结果进行了比较和校验,同时对废气中的干扰因素进行分离试验。结果表明,碘量法和定电位电解法测定裂解装置催化再生尾气焚烧废气中的二氧化硫,两种方法测定结果无显著性差异。
The concentration of SO2 in exhaust flue gas of catalytic cracking regeneration device was determined,which was desulfurized by seawater.This paper compared and checked the accuracy of the results determined by iodometric titration and constant potential electrolysis,respectively,and seperated the interference factors of the gas.The results indicated that determining SO2 in exhaust flue gas of catalytic cracking regeneration device by iodometric titration and constant potential electrolysis,there were no significant difference between the two methods.
