Calculates distillation stages from relative volatility and feed/product specifications using the McCabe-Thiele method and Fenske equation for minimum stages. Fenske equation: N_min = log[(x_D(1−x_B))/(x_B(1−x_D))]/log(α) — for α = 2 and 99% purity from 50% feed, N_min ≈ 10 stages.
Inputs
X Feed
Reference formula or conversion factor shown for context.
Alpha
Annualised standard deviation of returns, as a decimal (e.g. 0.2 for 20%). Higher volatility increases option value. Implied vol is derived from market prices.
Q Feed
Reference formula or conversion factor shown for context.
Reflux Ratio
Reference formula or conversion factor shown for context.
Results
estimated distillate xD (equilibrium)
The value at the specified point or condition.
theoretical stages N (Fenske equation)
The phase or stage in the progression determined by the computed value.
operating line L/V
A standardised quality or risk rating on the applicable scale.
Fenske: N = log[(xD/xB)·(1−xB)/(1−xD)] / log(α)
Sample size or count used in the calculation.
relative volatility α
The value at the specified point or condition.
