Equilibrium Constants

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...

A reaction object contains parameters that describe a chemical reaction scheme in terms of reagents, reaction steps, rate constants and equilibrium constants. The reaction can be evaluated to provide concentrations of species as a function of time and starting concentration. The reaction can also...

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...

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...

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...

In Python, any variable can be re-bound at will -- and modules don't let you define special methods such as an instance's __setattr__ to stop attribute re-binding. This script allows you to manage constants in Python.
