Abstract
Biodiesel is a recommended petroleum-based diesel substitute mainly because it is environmentally friendly and is a renewable, domestic resource. Six different continuous homogeneous alkali-catalyzed, heterogeneous alkali-catalyzed and supercritical methanolysis processes with and without adding tetrahydrofuran as a co-solvent to produce biodiesel from virgin vegetable oil were designed and simulated in this thesis. Also, economic assessment and sensitivity analysis were also performed based on the results of process simulations. The homogeneous alkali-catalyzed process was the best process technically and economically with the heterogeneous alkali-catalyzed process to compete with. While the addition of tetrahydrofuran as a co-solvent didn{u2019}t have a great impact on the technical and economic performance
