脱硫系统中碱液及污水氯离子含量的测定研究

Study on the Determination of Alkaline and Water Content of Chlorine Ion in the Desulfurization System

主要研究兰州石化公司炼油厂300万/年烟气脱硫装置中碱液及含硫污水中氯离子含量的测定,结合烟气脱硫装置工艺特点,在银量沉淀滴定法(莫尔法)的基础上设计制定了相应的分析方法。拓宽了检测范围,并使用该方法和其他分析方法进行对比,结果表明该方法的准确度较好,可及时准确的配合生产分析。

The determination of alkali and chloride ion content of sour water in 3000000 / year refinery gas desulfu- rization unit of Lanzhou Petrochemical Company is researched, combined with FGD process characteristics, precipi- tation titration in silver content （ Mohr ） is designed based on the established corresponding analysis method. At the same time, the detection range was widened, and compared with other methods, the results show that the meth- od is accurate, can be matched with the production of timely and accurate.
