Phase Equilibria

  • You cannot add records

IUPAC-NIST Solubility Data Series

Mutual solubilities and liquid-liquid equilibria of binary, ternary and quaternary systems, solvents and solutes include water, sea water, inorganic compounds, and a variety of organic compounds.



Software package by John Carroll for predicting fluid phase equilibria in natural gas-water systems; runs under DOS. Site also includes some excellent tutorials on phase equilibrium calculations and an introduction to gas hydrates.



Free Lite version of a program that solves equilibrium problems from a wide range of fields using the unified theoretical approach and algorithms of Smith and Missen. For MS Windows.


Fluid Phase Equilibria Page

From Quest Consultants, online calculator for the vapor pressure curve of a pure component or the pressure-temperature phase envelope of a mixture, uses the Peng-Robinson equation of state.


Gas-Vapor Phase Equilibrium Calculations

A mini-tutorial by W. R. Smith that discusses the calculation of dew-point temperatures and pressures in gas-vapor systems.


MINEQL+, A Chemical Equilibrium Modeling System

Software for the calculation of chemical equilibria. Includes graphical display of output, calculation of acid/base, redox and precipitation reactions, surface adsorption calculations, synthetic titrations.
