Abstract
This research investigates the transesterification process of five key fatty acids (palmitic, stearic, oleic, linoleic and arachidic) derived from Azadirachta indica for the production of methylated esters. The study focuses on evaluating the thermodynamic properties of these individual fatty acids to understand their behaviour during the transesterification process. Using the RADFRAC module in Aspen, a comprehensive simulation of the reactive distillation process is conducted to optimize conditions and enhance the efficiency of methylated ester production. The choice of these specific fatty acids aims to explore the diverse composition of Azadirachta indica and its potential application in biodiesel production. The simulation results provide insights into the complex interactions within the reactive distillation column, offering a valuable contribution to the understanding and optimization of transesterification processes. This research bridges the gap between theoretical understanding and practical application, paving the way for sustainable and efficient biofuel production from Azadirachta indica fatty acids.
