Abstract

As the demand for energy is ever increasing, biodiesel has become a major alternative to fossil fuels, primarily due to the latter's depletion rate. In methanol-water rectification, a vital part of the biodiesel production process, distillation is the preferred technique to recover methanol from water. This study aims to investigate the excess Gibbs free energy (ΔG) behavior on methanol in a water mixture, for the binary system.
