Proposal for an ethanol plant saving water, energy and reducing stillage

Saving water is vital for the environmental sustainability of the processes; In this sense, in ethanolic fermentation it is used for the dilution of sugary honeys, for the treatment of yeast and cleaning operations. Reducing water in fermentation allows obtaining wines with a higher alcohol content and, therefore, reducing the generation of the effluent known as vinasse in the distillery. In the present work a high gravity fermentation process is proposed, with a temperature of 30 ° C, must feeding time of 20 hours and total time of 53 hours, obtaining as results a concentration of 126.12 g / L of ethanol, a 45.66% reduction in water consumption, a 38.03% reduction in stillage generation and a 38.35% reduction in energy consumption. Mathematical software was required for the resolution of the mathematical fermentation models and a chemical process simulator for the resolution of the mass and energy balances in the distillation columns.
