After convergence of the temperature loop, the liquid and vapor flow rates, Lj and Vj, can be corrected using energy balances (see Figure 6-1). For the general stage shown in Figure 6-3, the energy balance is
This equation is for 2 ≤ j ≤ N − 1. The liquid flow rates can be substituted in from a mass balance around the top of the column:
where 2 ≤ j ≤ N − 1.
Substituting Eqs. (6-21a) and ...
