Abstract
This work has performed to examine the operation status of regeneration and scrubber system of cold rolling mill plant and established the DIWS(Dip Injection Wet Scrubber) system for the removal of hydrochloric acid with micro bubble. When the initial 22.3 ppm of HCl gas was injected into the system, the average exhaust HCl gas was 0.59 ppm with the removal efficiency of 97.3%. Hydrochloric acid was effectively removed by DIWS system. In the long term monitoring for 10 hours by 5 minutes through TMS(Tele Monitoring System), the average exhaust HCl gas was stably kept 0.69 ppm, which was also verified by manual measurement.
