Abstract: | This article presents a new approach for incorporating process-integration tools into life cycle analysis (LCA) for biofuel
production. Process synthesis techniques using mass- and energy-integration tools are employed to generate various scenarios
for reducing mass and energy consumption in the process. The global implications of these changes and the associated trade-offs
are assessed using the LCA tool: GREET. The developed approach enables the consideration of several levels of process integration
while tracking the process economics and the reduction of the net greenhouse gas emissions. Several cases of biofuels with
different processing technologies have been considered in this study, and the results show that when the process-integration
tools are effectively utilized and combined with LCA, better insights are obtained and the net greenhouse gas emissions decrease
drastically for different biofuels. |
