### Solving Mass Balances on a Distillation Column - Wolfram

Details. For the option "two unknowns," a binary mixture is fed to a distillation column. Two of the six variables (, and are the feed, distillate and bottoms flow rates (kmol/h), and , and are the feed, distillate and bottoms mass fractions of component 1) are unknown, and their values are obtained from these mass balances:

### Mass and Energy Balances

To develop an equation in terms of mass flux, the mass balance equation is divided by to produce an equation with units of mass per unit time. Dividing equation 12 by and moving the first term on the right (mass at time t) to the left hand side yields the following equation. Note that each term in this equation has units of mass/time.
