초록

제강산업의 냉연 산회수 설비공정을 검토하였고, 공정에서 발생되는 염화수소 가스를 처리하기 위하여 마이크로버블이 발생되는 DIWS 시스템을 운전하였다. 염화수소 가스의 대기배출허용기준을 만족하기 위해서는 추가공정의 도입이 필요한 것으로 나타났다. DIWS 장치로 유입되는 평균 염화수소 가스의 농도는 22.3 ppm, 배출가스의 농도는 0.59 ppm으로 평균 제거율은 97.3%였다. TMS 장치에 의한 10시간 5분 간격 측정에서도 평균 0.69 ppm으로 안정적이었으며, 수동으로 측정하여 TMS 장치의 신뢰도를 검증하였다.

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.
