Chemical Engineering
McCabe-Thiele Method Calculator
Estimates the number of theoretical trays needed to separate a binary mixture by distillation given compositions, reflux ratio, and relative volatility. Useful for preliminary column design and feasibility studies.
Fill in the required fields to see your result.
Chemical Engineering
Fenske Equation Calculator
Compute the minimum number of theoretical equilibrium stages required for a binary distillation separation using the Fenske equation. The "best case" stage count at total reflux — actual columns need more stages because they operate at finite reflux.
