Abstract

Researches are being conducted worldwide to the development of new technologies for the production of liquid fuels from renewal resources. In this context, the production of bioethanol from sugar cane is one way to reduce consumption of petroleum crude, and to contribute with the reduction of environmental pollution, becoming an important alternative for the achivement of a sustainable development. Within the proposed scenario, the goal is to evaluate an effective way to reduce costs of the production of ethanol biofuel, which contributes to the economic viability of this alternative Taking this into consideration, this work has developed a software sensor for determination of biomass, substrate and product from secondary measures such as turbidity, pH, CO2 flow rate and temperature, using an artificial neural network that combines the mass balance equations with neural networks that describe the kinetics of the fermentation process. The fermentation process is as raw material a mixture of hydrolyzed and cane molasses 75% and 25% volume, respectively. This type of composition could be typical of the second generation of the ethanol production process (making use of the bagasse hydrolysis) coupled with processes of first generation (making use of the juice extracted from sugar cane, which it's a conventional process already exists).Thus the developments made in this work can be applied not only to conventional processes, but also to possible processes of second generation.
