Solving Mass Balances on a Distillation Column
This Demonstration shows the solution of mass balances around a distillation column. One or two feeds enter the column and a distillate stream leaves the top while a bottoms stream leaves the bottom of the column. The unknown variables are in blue; use sliders to select the correct values, then check "solution." Click the "new problem" button for a new problem. The three options correspond to a binary feed in a single feed stream, a two-component system with two feed streams, and a ternary feed in a single feed stream. For the binary systems, the mole fractions for component 1 are given (F = D + B, F2). For the ternary system, the mole fractions of components 1 and 2 are given.
