摘要：

In this work, alternative configurations to fermentation and distillation process for hydrous ethanol production were proposed and evaluated. Three configurations were analyzed: conventional fermentation and distillation (CFCD), vacuum extractive fermentation coupled with double effect distillation (VFDD) and vacuum extractive fermentation coupled with conventional distillation (VFCD). The VFDD configuration provided a significant reduction on energy consumption; however, ethanol losses were considerably high. Regarding ethanol recovery on the distillation process, VFCD configuration achieved the highest value (95.5%) among the studied processes.
