Abstract
The importance of improving industrial transformation processes to more efficient processes ones is part of the challenges of these times. Specifically, the development of more efficient processes in the production of biofuels where the reaction and separation processes can be intensified are of great interest to reduce the energy consumption associated with the process. In the case of Biodiesel, the process is defined by a chemical reaction and the components associated with the process, the thermochemical study seeks to develop calculations for the subsequent understanding of the reaction and purification project. Thus, the analysis of the mixed components using the Aspen Plus V9® process simulator describes the thermochemical study. For this, the UNIFAC-DMD thermodynamic method was used to estimate the binary parameters of the equilibrium of the raw materials and reactants calculated with the simulator. The observation of the analyzed aspects shows the behavior of the components at different temperature conditions, the azeotropic behavior and thermochemical conditions were determined.
