Solving Mass Balances on a Distillation Column

This simulation allows you to test yourself on your ability to perform mass balances. Three scenarios are given; each scenario has a mass flow rate and at least one mole fraction that needs to be solved for. The equations needed to solve each mass balance are given by pressing “Details”. Each question displays the correct answer after you press “Show solution”, so you get instant feedback on your performance. This simulation displays your score at the end, so you may submit a screenshot of your score as an assignment for a materials & energy balances class.
