GONZALEZ-CORTES, Meilyn et al. Cogeneration analysis in order to satisfy integrated productions of sugar and alcohol. RTQ [online]. 2017, vol.37, n.3, pp. 392-404. ISSN 2224-6185.

The possibility of process integration in the production of sugar and alcohol was evaluated through the exchange of raw matter such molasses, diluted juice, and bagasse from the sugar process for their use in the ethanol production. The energy integration was also carried out in these processes with the use of the pinch method, for that the cold and heat streams were analyzed with possibilities for it. The steam consumption was estimated in turbogenerators, exergetic efficiency and other were calculated too for a better knowledge of the operational state of the same ones, being these below the technical norms, for what intended a change in the cogeneration system for a better use of the system obtaining higher values for the efficiencies when comparing them with the installed technology. The economic balances were carried out in the cogeneration scheme and as result were obtained that support the possibility of the technology change, what would benefit to the processes of sugar and alcohol in the improvement of their productions, given the possibility to have a bigger availability for raw matter for both processes.
