Biodiesel is an excellent substitute for conventional diesel fuel because of being renewable, nontoxic, biodegradable and low emissions. This study concerns with production of methyl oleate-ester (biodiesel) using glyceryl trioleate and methanol with NaOH as a catalyst employing both traditional process and reactive distillation process. Aspen-Hysys v 8.0 is used for this simulation. The phase equilibrium was predicted by the Wilson thermodynamic model and the reactants are fed, methanol to olein oil (molar feed ratio = 6:1). Results reveal to that integrated design of (RD) ensures the removal of gylecrol by-product that shifts the chemical equilibrium to completion. Thus RD process are more efficient than traditional process for biodiesel production due to less units and lower energy consumption
