Abstract

In order to evaluate the fire and explosion involved and to ensure the safe and optimized operation of chemical processes, it is necessary to know combustion properties. Explosion limit is one of the major combustion properties used to determine the fire and explosion hazards of the flammable substances. In this study, the explosion limits of alcohols were predicted by using the normal boiling points and the flash points based on a solution theory. The values calculated by the proposed equations agreed with literature data within a few percent. From the given results, using the proposed methodology; it is Possible to Predict the explosion limits of the other flammable substances.

화학공정에서의 안전하고 최적화된 조작과 내재되어 있는 화재 및 폭발 위험성 평가를 위해서 연소 특성치를 알아야 한다. 폭발한계는 가연성물질의 화재 및 폭발위험성을 결정하는데 주요한 특성치 가운데 하나이다 본 연구에서, 알코올류의 폭발한계에 대해 용액론을 근거로 표준끓는점과 인화점을 이용하여 예측하였다. 제시된 예측식에 의한 예측값은 문헌값과 적은 오차범위에서 일치하였다. 제시된 방법론을 사용하여 다른 가연성 물질의 폭발한계 예측이 가능해졌다.
