In this study, the odor compounds emitted from the field workplaces at the Pohang steel complex were measured using analytical instruments and the olfactory method. In addition, the reduction of odor emissions by pyroligneous liquid was evaluated. The odor samples were obtained from slag pots and dry pits, which refrigerate hot slag, and the target compounds were hydrogen sulfide (H₂S) and ammonia (NH₃). The levels of odor emissions varied with meteorological and operating conditions, but emissions from dry pits were always much higher than those from slag pots. As the concentration of pyroligneous liquid increased, the concentrations of H₂S and the ratios of dilution decreased. Together with this result and the guideline of odor emissions, the increase of pyroligneous liquid (more than 2.5 times) in cooling water was suggested to reduce odor emissions. Actually, the reduced levels of H₂S at the slag pot and the dry pit were observed (70 and 94%, respectively) after the increased amount of pyroligneous liquid. However, in order to determine the optimal amount of pyroligneous liquid for the economical and efficient removal of odor emissions, the system of cooling water has to be improved and more samples are required for a comprehensive analysis.
