UNIFAC Calculator

UNIFAC Calculator is a tool developed by UNIFAC Calculator organization that allows users to calculate equilibrium properties of liquid-liquid and vapor-liquid systems using the UNIFAC (Universal Quasichemical Functional Group Activity Coefficients) method.

The UNIFAC method is an activity coefficient model widely used in chemical engineering to predict phase equilibria and properties in various industrial processes. It takes into account the molecular structure of chemical components to estimate their thermodynamic properties and interaction behavior.

UNIFAC Calculator utilizes the UNIFAC model to calculate activity coefficients, excess Gibbs free energy, liquid phase compositions, and other equilibrium properties of liquid-liquid and vapor-liquid systems. It requires input parameters such as temperature, pressure, component information, and interaction parameters to provide accurate results.

UNIFAC Calculator can be used to simulate phase equilibria and properties of liquid-liquid and vapor-liquid systems, including multicomponent mixtures, ideal and non-ideal solutions, pure components, and more.

Some key features of UNIFAC Calculator include support for multiple unit systems, customizable component libraries, interactive input interface, advanced parameter estimation methods, graphical representation of results, and export capabilities for further analysis.

Yes, UNIFAC Calculator is available for free and can be accessed online or downloaded for offline use. The organization behind UNIFAC Calculator aims to support education, research, and industrial applications by providing an accessible and reliable tool.

The accuracy of UNIFAC Calculator depends on the quality of input data, such as component information and interaction parameters. When used with appropriate and accurate data, UNIFAC Calculator is capable of providing reliable phase equilibrium predictions.
