Abstract

Abstract This study proposes an innovative biodiesel technology based on heat-integrated reactive absorption. Rigorous simulations embedding experimental results were performed in AspenTech AspenONE engineering suite to design this novel process and evaluate the technical and economical feasibility. The main results are given for a plant producing 10 ktpy biodiesel from waste vegetable oil with high free fatty acids content, using solid acids as green catalysts. This innovative process eliminates all conventional catalyst related operations, and efficiently uses the raw materials and the reactor volume in an integrated setup that allows significant savings in capital and operating costs.
