摘要：This paper presents the application of a GUI developed in Matlab� for a binary distillation column simulation, where the diameter, height, tray number, feed tray location and the heat flux in the condenser and reboiler were calculated for a given operational condition set by the user, like the feed condition, distillation and bottom molar fraction, reflux ratio, top, bottom and subcooling temperature of distillate. The program, called DTMB-UA v1.0 (Design of a distillation Tower for Binary Mixture-Universidad del Atl�ntico), uses the combination of material and energy balances, experimental equations of phase equilibrium and constant relative volatility, reported in the literature. The general procedure to calculate the outputs in the program start by selecting the type of phase equilibrium curve calculation, between the constant volatility and the experimental data; in the case of constant volatility, the vapor and liquid mean temperature, mean tower pressure and densities are estimated based on a set of empirical equations for the column diameter, column height, theoretical tray numbers, and energy requirement on the condenser and reboiler. The same steps are applied when using experimental data for the equilibrium curve, consisting in inputs of temperatures and molar fractions of the component with higher volatility in the liquid and the vapor phase. The last step is to select a binary mixture from the given by the software. The material balance is represented as the operation lines on the x-y diagram according to the McCabe-Thiele method. It was found the exact composition of the bottom molar fraction, the effect of reflux ratio on the distillation molar fraction under different tray numbers and the effect of feed quality variation on condenser and reboiler duties under different reflux ratio.
