Separation Systems Reference

Packed Column Sizing

Flooding velocity (Generalized Pressure Drop Correlation):

V_f = K_v * sqrt((ρ_L - ρ_V) / ρ_V)

Where:
V_f = flooding velocity
K_v = packing constant
ρ_L = liquid density
ρ_V = vapor density

McCabe-Thiele Method

Minimum reflux ratio (Underwood's method):

R_m = (x_D / (α - 1)) * (1 / (x_F - x_D))

Where:
R_m = minimum reflux ratio
x_D = distillate composition
x_F = feed composition
α = relative volatility
