| Abstract: | To eliminate the harm caused by excessive free chlorine in the production of Chlor-alkali industrial hydrochloric acid,and to improve the quality of hydrochloric acid,the control and analysis of free chlorine content in hydrochloric acid are discussed,and the accuracy and precision tests are done.The results show that proper control of the pressure fluctuation of chlorine and hydrogen,the ratio of chlorine and hydrogen and the instability of pumping force of the jet pump can effectively determine the content of free chlorine in hydrochloric acid.Iodometry used to analyze the content of free chlorine proves to be simple and fast with good reproducibility,which provides accurate reference for process control. |
