ABSTRACT
This chapter focuses on the optimization of butanol production to obtain designs that accomplish economic and environmental targets. Biobutanol can be produced by fermentation using Clostridium bacteria. Biofuel production from biofuel feedstocks would drastically reduce greenhouse gas emissions, thereby providing a sustainable future. There is global demand for butanol and it is produced by petrochemical methods. There are several studies on the metabolism of solventogenic Clostridium species, which comprises two clearly distinctive phases: solventogenics and acidogenics. Several techniques have been proposed for the separation unit, highlighting adsorption, liquid–liquid extraction, pervaporation, and gas stripping. An integrated reactor made possible to improve the production of biobutanol by fermentation. The optimization applied to process design is a very useful tool to obtain design, which accomplishes several objective functions such as economic and environmental. The multi-objective optimization approach was implemented using a hybrid platform with Microsoft Excel and Aspen Plus.
