Consider a binary mixture of water and nitromethane at 1 atm. This mixture exhibits the vapor-liquid equilibrium behavior of partially miscible mixtures (equilibrium data is available in [1]). Thus, in order to separate water from nitromethane, one has to use a two-column system with an intermediate decanter. This Demonstration shows the required operational setup, which will produce two product streams: a pure water stream and a water-free stream.
