Ideal Equilibrium StagesIdeal Equilibrium StagesIn distillation, the separation is based on the different composition between vapor and liquid at equilibrium conditions; thus, the concept and the definition of an ideal equilibrium stage are fundamental for the understanding of distillation processes.
An ideal stage is a device where one or more material or energy streams enter and one liquid and one vapor stream leave in thermodynamic equilibrium.
Examples of ideal equilibrium stages are shown in Fig. 1-4. Stages shown in Fig. 1-4f and …
