Colombia's policy of adding oxygenates to gasoline has led to the development, analysis and improvement of its bioethanol industry. Three bioethanol production pathways from sugarcane were simulated using Aspen Plus and compared using exergy analysis. These correspond to first generation bioethanol (route 1), second generation bioethanol (route 2) and bioethanol joint production (route 3). The objective was to determine whether there is an exergetic improvement in the bioethanol joint production compared to the individual processes. The bioethanol production was 491, 1616 and 2,049 kg/h, and irreversibilities amounted to 17.89;19.31 y 19.85 MJ/kg ethanol, respectively. As a result, it was concluded that the joint production does not present an exergetic improvement compared to individual processes.
