ALOHA 모델을 이용한 태양전지 제조공정의 암모니아가스 누출 평가

초록

This study provides a comparison and analysis of the predicted damages related to hazardous chemical substancesused in “A” solar cell manufacturing process. In order to predict potential damages, different accident scenarioswere established using the ALOHA model and the KOSHA guideline. This study evaluates chemical spills andleaks from cylinder and pipeline. Maximum distance of chemical movement, based on an initial concentration of150 ppm, was estimated as up to 258 m in summer and 251 m in winter. The impacts of the leakage of chemicalssuch as ammonia, were dependent on the initial concentration of the chemical leaked, the atmospheric stabilityand temperature, and the wind speed. All of those however, were affected by air humidity.
