Abstract

ALONSO-ESTRADA, Dania et al. Energetic and Environmental Integration in Factories of Sugar Cane Byproducts. Rev Cie Téc Agr [online]. 2020, vol.29, n.2, pp.32-41.  Epub June 01, 2020. ISSN 2071-0054.

Anaerobic treatment is an alternative to treat residual of the ethanol production process to produce biogas as renewable energy. The purpose of this study is the use of Microsoft Excel, Solver and SolverTable add-ins for the simulation of processes in an agroindustrial complex. It is formed by a torula yeast plant that operates with vinasse as a carbon source and the production of biogas using digesters of the UASB type for the management of some vinasse and the residual of the process of torula yeast production. The study considers an ethanol production capacity of 90,000 L/d and a maximum yeast production of 30 t/d. The results show that the energy demand of a production of 17 t/d of yeast can be satisfied by the generation of biogas and a waste out COD concentration between 11 and 17 kg/m3.

Keywords : bioethanol waste; torula yeast waste; biogas.
