Using Vapor-Liquid Data in Distillation

Vapor-liquid equilibrium helps explain how liquid mixtures separate in distillation. Distillation is a process that separates liquids by their boiling point. A liquid mixture is fed into a distillation unit or column and then boiled.

As the mixture heats, the component with the lower boiling poin...

Understanding the distribution of chemical components in both the vapor and liquid phase, called vapor-liquid equilibrium is essential to the design, operation, and analysis of many engineering processes. Vapor-liquid equilibrium or VLE is a state at which a pure component or mixture exists in both the liquid and vapor phases. The phases are at ...
