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.

El tratamiento anaeróbico es una alternativa de tratamiento del residuo del proceso de producción de etanol para producir biogás como energía renovable. El propósito de este estudio es la simulación con Microsoft Excel y los complementos Solver y SolverTable de un complejo agroindustrial formado por una planta de levadura torula que opera con vinaza como fuente de carbono y la producción de biogás utilizando digestores del Tipo UASB para el manejo de una parte de la vinaza y el residuo del proceso de producción de levadura torula. El estudio considera una capacidad de producción de etanol de 90,000 L / dy una producción máxima de levadura de 30 t/d. Los resultados muestran que la demanda de energía de una producción de 17 t/d de levadura puede satisfacerse mediante la generación de biogás y se obtiene una concentración de DQO a la salida que oscila entre 11 y 17 kg / m3.
