Abstract
This work presents an ChemCAD 6.0 Simulation study for biodiesel production. The simulation illustrates the production of biofuel from pure vegetable oil with an alkaline catalyst. The main areas are transesterification, methanol separation, water washing, FAME purification, catalyst neutralization and glycerol purification. The equipment used includes in particular reactors, distillation and extraction columns and components splitters. As a result of the simulation, the two final target products - biodiesel and glycerol, are obtained with purity 98% and 99%, respectively. The suggested technological scheme provides a possibility for recuperation of the heat streams.
