Abstract
In the present paper, an integrated scheme of first and second-generation bioethanol production is proposed to increase the yield and decreasing thermal energy and freshwater requirements. In this sense, an energy consumption reduction of the integrated process was evaluated through heat exchangers network integration, applying mathematical programming. Then, to reduce freshwater consumption, streams with water disposal for re-use in the process was evaluated, formulating the problem as a mixed-integer nonlinear programming problem (MINLP). Bioethanol production from the integrated scheme increased at least 40% compared it with sugar-bioethanol production scheme. The heat exchanger network with the minimum annual cost was identified. Around of 16% of freshwater consumption was minimized using a nonconvex nonlinear programming NLP. The integration of second-generation bioethanol to a sugar-bioethanol process could increase, the bioethanol production in Colombia, without an energy and water excessive consumption.
