For the typical process flow of five towers and its component, pressure, temperature, thermodynamic equilibrium equations and thermodynamic data for ethanol distillation process simulation were analyzed and determined. The simulation results show that the SRKM, IDEAL and the binary interaction data parameters for the NRTL were feasible to simulate the ethanol distillation process. The simulation results were in good agreement with the design data of the ethanol disti]Jation process with five towers, and the relative errors were less than 4. 5%.
