Liquid-liquid equilibria for the canola oil biodiesel plus ethanol plus glycerol system

resumo

The knowledge and accurate description of the phase equilibria of systems containing transesterification products are essential for a correct operation and optimization of the biodiesel production and purification units. To overcome the lack of phase equilibria information concerning systems from the transesterification reaction with ethanol, in this work, liquid-liquid equilibria data, tie-lines and phase boundaries, have been measured for the ternary system canola oil biodiesel + ethanol + glycerol at temperatures between 303.15 and 333.15 K. Following previous successful applications to other biodiesel systems, the Cubic-Plus-Association (CPA) equation of state was also applied here to predict the experimental data, using previously established interaction parameters, with average deviations inferior to 3%.
