요약
인화점은 산업현장에서 화재 및 폭발의 위험성을 결정하는데 사용되는 중요한 지표의 하나로 안정성 평가 시 많이 사용되고 있다. 따라서 본 연구는 고무제조 공정에서 주로 쓰이는 이성분계 혼합물 중 {toluene+ethylbenzene}, {methlycyclohenxane+ethylbenzene} 그리고 {n-heptane+ethylbenzene} 대한 인화점을 101.3 kPa에서 SETA 밀폐식 인화점 측정기를 이용하여 측정하였다. 각 이성분계에 대하여 Raoult's의 법칙, Wilson, NRTL 및 UNIQUAC 파라미터를 이용하여 혼합물에 대한 인화점 예측하고 실험 결과와 비교하였다. 비교 결과 모든 예측값과 실험값은 유사한 값을 보였고 편차가 1.74 K이내의 결과를 보였다.
Abstract
Flammable substances are used in laboratories and industrial process. The flash point (FP) is one of the most important physical properties used to determine the potential for characterizing the fire and explosion hazard of liquids. The FP data at 101.3 kPa were measured for the binary systems {toluene+ethylbenzene}, {methlycyclohenxane+ethylbenzene} and {n-heptane+ ethylbenzene}. The experiments were performed according to the standard test method (ASTM D 3278) using a SETA closed cup flash point tester. The measured FPs were compared with the values predicted using the following activity coefficient models: Wilson, Non-Random Two Liquid (NRTL), and UNIversal QUAsiChemical (UNIQUAC). The average absolute deviation between the predicted and measured lower FP was less than 1.74 K.
Key Words: Flash Point, Seta Closed Cup Tester, Binary System, Activity Coefficient Models
