Optimization of Biodiesel Production using Aspen Plus

Abstract

With the continuous increase in energy demand and also simultaneously depletion of fossil fuels made it necessary to research of other alternative sustainable sources of energy. The most promising alternatives include biofuels, especially biodiesel. Here ASPEN Plus software is utilized for a better understanding of models, procedures associated with producing biodiesel. Analyses were also conducted by varying operating parameters to find out how they affect separation throughout the process. In this project, different models and configurations for producing biodiesel are considered. Models for both trans-esterification and esterification process are designed. In each model, parametric study is done to find optimum parameters at which maximum conversion is obtained and also process is modeled such that heat duty is minimized. Sensitivity analyses are also carried to analyze behavior of all components.
