액체염소의 Pool vaporization에 따른 위험성 평가에 대한 연구

초록

In this study, quantitative risk assessment of liquid chlorine was conducted. In discharge modeling, the rate that liquid chlorine dropped as droplets after the initial leak was estimated. The maximum downwind distance was calculated by selecting 30 ppm of end point of toxic cloud diffusion. In this study, overall diffusion process is divided into segments for accurate diffusion modeling. Toxic cloud diffusion and surface evaporation were simultaneously analyzed by dividing several segments. The individual risk was presented in the form of contour lines, and the social risk was expressed by the FN curve. All risks were unacceptable, so risk mitigation measures were essential.
