Distillation Unit Operations
Process Models Overview
DistillationTray: Individual theoretical tray model for binary vapor-liquid equilibrium with material balance dynamics. Essential for multi-component separation analysis and control design in distillation columns, absorption towers, and stripping operations.
BinaryDistillationColumn: Complete multi-tray column model integrating individual tray dynamics with reflux drum and reboiler for binary separations. Suitable for control design, optimization, and dynamic simulation of industrial distillation processes.
