Estudo de impacto da aplicação de sistema de arrefecimento de selo de bomba centrífuga na redução dos custos de manutenção e no reaproveitamento hídrico em uma usina sucroalcooleira

Abstract

This study aimed to evaluate the impact of implementing a cooling system for mechanical seals in centrifugal pumps at a sugar and ethanol plant, focusing on reducing maintenance costs and the number of seal failures, as well as promoting water reuse and assessing the return on investment of the new project. The research was conducted through a case study, involving the collection of operational data that allowed a comparison between the periods before and after the implementation of the new solution. Indicators such as failure frequency, mean time between failures (MTBF), volume of water consumed, maintenance costs, and the amount invested were considered. The new system will operated in a closed-loop configuration, reusing water from another process, resulting in resource savings and greater stability in seal cooling. The study demonstrated the technical and economic effectiveness of the implemented solution and contributed to the adoption of sustainable practices in the industrial sector.
