Abstract
Steam economy is one of the main indicators of energy performance in multiple-effect evaporation systems used in the sugar industry. The objective of this study was to analyze the steam economy of a five-effect evaporation system using a quantitative approach and a quasi-experimental design based on real operational data. The influence of Brix degrees and the mass flow rate of clarified juice was evaluated through a multiple linear regression model, whose significance was verified by statistical analysis. The results showed that an increase in mass flow rate improves steam economy, whereas higher initial juice concentrations reduce its value. The obtained model showed high predictive capacity and made it possible to identify operational conditions that optimize steam utilization. It is concluded that mathematical modeling constitutes a useful tool for improving energy efficiency and supporting decision-making in the sugar industry.
