In this simulation, you can construct a ternary phase diagram step by step using the Hunter-Nash method to determine the number of equilibrium stages needed to achieve a certain separation. Press the “new problem” button to generate a new set of conditions; pressing this button takes you back to the beginning of the simulation. Check “solution” to see the answer. Once you check “solution”, you cannot change your answers. Click “next” to move onto the next step, but once you press “next”, you cannot go backward.
