Equation Correction

There was an error in the original article []. The expression (1-q)∙F was positioned at a wrong location in Sections 4.2 and 4.3. Note that this expression usually cancels out for a liquid boiling feed stream. It is only important in the case of a different feed state. A correction was made to Equations (19), (21), (22) and (23) and to Figure 8.

V_{m i n, B C} = V^{T, C_{21}} - V^{B, C_{21}} = \sum_{i = 1}^{n} \frac{α_{i} \cdot z_{i} \cdot F}{α_{i} - θ_{A}^{’}} \cdot r_{i}^{T, C_{1}} = \frac{α_{A} \cdot F \cdot z_{A} \cdot r_{A}^{T, C_{1}}}{α_{A} - θ_{A}^{’}} + \frac{α_{B} \cdot F \cdot z_{B} \cdot r_{B}^{T, C_{1}}}{α_{B} - θ_{A}^{’}}

(19)

- V_{m i n, B C} + (1 - q) \cdot F = V^{T, C_{22}} - V^{B, C_{22}} = \sum_{i = 1}^{n} \frac{α_{i} \cdot z_{i} \cdot F}{α_{i} - θ_{C}^{’}} \cdot r_{i}^{B, C_{1}} = \frac{α_{C} \cdot F \cdot z_{C} \cdot (1 - r_{C}^{T, C_{1}})}{α_{C} - θ_{C}^{’}} + \frac{α_{D} \cdot F \cdot z_{D} \cdot (1 - r_{D}^{T, C_{1}})}{α_{D} - θ_{C}^{’}}

(21)

V_{m i n, C D}^{’} = V^{B, C_{22}} + (1 - q) \cdot F = V^{T, C_{22}} + V_{m i n, B C} - (1 - q) \cdot F + (1 - q) \cdot F = \frac{α_{C} \cdot F \cdot z_{C} \cdot r_{C}^{T, C_{22}}}{α_{C} - θ_{C}^{’}} + V_{m i n, B C}

(22)

V^{T, C_{1}} = \frac{α_{A} \cdot F \cdot z_{A} \cdot r_{A}^{T, C_{1}}}{α_{A} - Φ^{C_{1}}} + \frac{α_{B} \cdot F \cdot z_{B} \cdot r_{B}^{T, C_{1}}}{α_{B} - Φ^{C_{1}}} = V_{m i n, B C}

(23)

In addition, in Figure 8, a modification had to be made (see Figure 1).
