    When there is a lack of possibilities to conduct experiments in industrial dimensions for simulations and optimizations of influential parameters or desirability responses, professional software products are used. So, the objective of this paper is the application of CHEMCAD software for chemical processes simulations and the MINITAB software for mathematical modeling and process parameters' optimizations. The materials used in processes simulations are ethanol and n-propanol in liquid-vapor stream. For influential parameters' optimizations (number of tries, reflux and feed tries) used as experiments design, the method used is called full factorial design second order (FFD). With the increase of feed temperature from 25 to 40 oC and increased number of tries from 12 to 24, it varies the amount of distillate and the amount of bottom stream in accordance to the desirability of responses. The distillation tray column is an adequate method for separation. The experiments design uses full factorial design of second order to provide reliable equations for parameters' optimizations.
