요약
인화점은 공정안전을 평가할 때 산업공정에서 가연성 액체의 중요한 연소 특성 가운데 하나이다. 본 연구에서는 클리브랜드 개방식 장치를 사용하여 n-propanol + formic acid계와 acetic acid + propionic acid계의 인화점을 측정하였다. 실험값은 Raoult의 법칙과 최적화 기법에 의해 추산된 값과 비교하였다. 그 결과, 최적화 기법에 의한 추산값이 Raoult의 법칙에 의한 추산값 보다 실험값에 더욱 근접하였다.
Abstract
The flash point is one of the most significant combustion properties of flammable liquids in industrial processes when evaluation process safety, In this paper, Cleveland open cup tester is used to measure the flash points for the two binary systems (n-propanol + formic acid and acetic acid + propionic acid). The measured flash points were compared with the values calculated by the Raoult's law and the optimization method using van Laar and Wilson equations. The calculated values based on the optimization method were found to be better than those based on the Raoult's law.
Key Words: Flash point, Raoult's law, van Laar, Wilson, Optimization method
