What Does VLE Stand For?

VLE stands for Vapor Liquid Equilibrium

Vapor Liquid Equilibrium (VLE) refers to the condition in which a vapor phase and a liquid phase of a substance coexist in a balanced state, where the rate of evaporation of the liquid equals the rate of condensation of the vapor. This equilibrium is essential in various processes, including distillation, refrigeration, and chemical engineering, as it helps determine properties such as phase composition, pressure, and temperature relationships in mixtures. Understanding VLE is crucial for optimizing industrial operations and designing separation processes.
