Teorijska obravnava faznega ravnotežja tekočina-para

diplomsko delo

Abstract

V diplomski nalogi sem obravnaval fazna ravnotežja tekočina-para etanola in benzena. Iz literaturnih virov sem pridobil eksperimentalne podatke za parne tlake pri različnih temperaturah. Za izračun parnih tlakov pri temperaturah od temperature tališča do kritične temperature sem uporabil Clausius-Clapeyronovo in Wagnerjevo enačbo. Pri primerjavi rezultatov obeh enačb sem ugotovil, da Clausius-Clapeyronova enačba pri nizkih temperaturah dobro opiše fazno ravnotežje, pri visokih temperaturah pa pride do velikega odstopanja.

Secondary title:	Theoretical study of the liquid-vapour phase equilibrium
Secondary abstract:	In my bachelor’s thesis I dealt with the liquid-vapor phase equilibria of ethanol and benzene. I obtained the experimental data for the vapour pressure at different temperatures from the literature sources. I used the Clausius-Clapeyron and Wagner equations to calculate the vapour pressures at the temperatures from the melting point to the critical temperature. When comparing the results of both equations I found that the Clausius-Clapeyron equation describes the phase equilibrium at low temperatures well and that large deviations occur at high temperatures.
