Abstract
This study was carried out to develop the realtime evaluation system of $NH_3$ absorption efficiency with gas sensors which were installed on the inlet and outlet of lab-scale scrubber system. The $NH_3$ absorption amount, calculated by sensor outcomes for 3 hr, 6 hr, and 12 hr of absorption process, was compared with the results analysed by Indo-phenol method for the absorption solution. Even though the difference between two methods was about 20%, the correlation coefficient between the two results was very high, more than 0.99. In addition, we could find very good correlation between pH, absorption amount and reaction time. Also we could find out the breakthrough time in the middle of absorption process. With more diverse experiment in the future, we can make gas sensor system for the realtime evaluation of the odor and/or air pollution treatment efficiency.
