This project documents the energy analysis of a butanol extraction process using supercritical carbon dioxide. Production of butanol as a biofuel has gained popularity in recent years but is limited by operating conditions of bacteria used for production and current extraction technologies. The project utilizes butanol production by B. megaterium and a continuous, in-situ supercritical carbon dioxide extraction and separation process as a method of reducing overall energy usage. Through energy analysis, the production and extraction process proved to be more efficient than other current methods. Recommendations include process design optimization and construction of a pilot model. These findings serve as support for increased research and commercialization of this extraction method.
