Equilibrium Constants Computation using the Soave-Redlich-Kwong equation of state In the program, we obtain equilibrium constants, compressibility factors, molar volumes and densities using the Soave-Redlich-Kwong equation of state. We find the same results as those given by Henley and Seader in Equilibrium-Stage Separation Operations in Chemical Engineering, Wiley, 1981...

Vapor-Liquid Equilibrium Diagram of Ethane-Benzene at 25dlT-C and 175dlT-C The programs compute the vapor-liquid diagram of an ethane-benzene mixture at 25dlT-C and 175dlT-C. This binary mixture exhibits a peculiar behavior because the volatilities of ethane and benzene are very different. We use the SRK equation of state to compute equilibrium constants. This problem...

Phase Envelope for Ethane-Benzene Mixture The program computes phase envelopes for two binary mixtures containing ethane and benzene (20 % ethane and 80 % benzene; 70 % ethane and 30 % benzene). This binary system exhibits a peculiar behavior called retrograde condensation (e.g. We get condensation as we increase the temperature or...

Flash Calculations using the Soave-Redlich-Kwong equation of state In the programs, we perform flash calculations of a mixture of hydrocarbons (ethane, propane, n-butane and n-pentane) using the Rachford-Rice equation. The phi-phi method, based on the SRK equation of state, is used to compute the equilibrium constants. We also find the True Vapor Pressure. All...
