What Does UNIFAC Stand For?

UNIFAC stands for Universal Quasichem Functional Group Activity Coeffs

UNIFAC, or Universal Quasichem Functional Group Activity Coefficients, is a predictive thermodynamic model used in chemical engineering and physical chemistry to estimate activity coefficients for mixtures. By breaking down complex mixtures into functional groups, UNIFAC facilitates the calculation of phase equilibria and properties of solutions, enabling more efficient design and optimization of industrial processes. Its applicability across a wide range of systems makes it a valuable tool for researchers and engineers in fields such as separation processes and process simulation.
