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 lower explosion and upper explosion limits of esters were predicted by using the heat of combustion. 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 ester 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, 에스테르류의 폭발하한계와 상한계에 대해 연소열을 이용하여 예측하였다. 제시된 예측식에 의한 예측값은 문헌값과 적은 오차범위에서 일치하였다. 제시된 방법론을 사용하여 다른 가연성 에스테르류의 폭발한계 예측이 가능해졌다.
