Abstract

This work proposes the implementation of a pilot plant for the production of xylitol from sugarcane bagasse. To calculate the production capacity of the proposed plant, a processing capacity of 5 tons of sugarcane bagasse per day was considered, resulting in the production of 280 kg/day of xylitol. Mass and energy balances were used to quantify all input and output streams of this production process. Following the biorefinery concept, the pilot plant was integrated into a sugar mill, and then Pinch analysis was applied to optimize the energy consumption of the process while maximizing its recovery. Using the hot and cold streams from the sugar mill and the xylitol plant, a heat exchange network was developed to integrate both production processes. According to the results of the energy evaluation, a Pinch temperature of 50ºC was observed, a minimum consumption of 95921 kJ of hot utility and 491802 kJ of cold utility, and a heat recovery of 630330 kJ, resulting in a 53% reduction in water consumption in the heat exchange operation.
