⚗️ Fenske-Underwood-Gilliland (Minimum Reflux Ratio Rm, Number of Stages N & HETP)

Batch Distillation Column Sizing Calculator

Size structured packing and tray columns for solvent recovery and chemical purification batch distillation using the classical Fenske-Underwood-Gilliland shortcut method: calculate minimum reflux ratio ($R_m$), determine required number of theoretical equilibrium stages ($N$), determine packing Height Equivalent to a Theoretical Plate (HETP in inches), and process yields.
