Fazna ravnotežja v dvokomponentnih sistemih

Kržan, Nina (author), Jamnik, Andrej (mentor)

V diplomski nalogi sem obravnavala fazni diagram neidealne mešanice metanol-ogljikov tetraklorid pri temperaturi 35 ˚C. Izračunala sem celotni parni tlak mešanice z metodo UNIFAC, ki temelji na izračunu aktivnostnih koeficientov pri različnih sestavah mešanice. Za njegov izračun, ki je ločen na dva dela – kombinatoričnega in rezidualnega, sem si pomagala s Tabelo 8-23 iz knjige Properties of Gases and Liquids. Dobljene rezultate sem podala v tabelah in diagramih.

Abstract

In the bachelor’s thesis, I studied the phase diagram of the nonideal mixture methanol-carbon tetrachloride at the temperature of 35 ˚C. I calculated the total vapor pressure of the mixture using UNIFAC method based on the calculation of activity coefficients at different compositions of the mixture. For this calculation which is divided into two parts – the combinatorial and residual part, I helped myself with the Table 8-23 from the book Properties of Gases and Liquids. I presented the results of these calculations in the tables and graphs.
