The molar hold-up of the condenser and reboiler are set equal to 2000 and 5000 kmol, respectively. The hold-up in the reactive and nonreactive trays is chosen to be 200 kmol. The reaction rate constant is equal to 5 and the Damköhler number defined by is 100.

This Demonstration shows the distillate and bottom compositions versus time for components , , , and (in blue, magenta, brown, and green, respectively) for user-set values of the reboil and reflux ratios.

Two snapshots show good conditions where almost pure and exit the column. This can only be achieved if the distillate and bottom flow rates are equal, which is always the case if the reboil ratio, , and the reflow ratio, , are chosen so that . Hence, this reactive distillation setup can achieve conversions near 100% in addition to the simplification of the operation scheme: no reactor is followed by separation units and there is no recycling of unreacted components and .
