Optimización del Proceso de Regeneración de Resinas de Intercambio Iónico para ser Utilizadas en el Desmineralizador de Agua de la Refinería Estatal Esmeraldas

Abstract

The present research work was carried out with the purpose of verifying the optimal conditions of regeneration of ion exchange resins, by means of laboratory tests that simulate the operation at industrial level, to identify the concentration of the regenerants. This simulation was achieved by placing resins in burettes and making the respective regenerant flow, and then passing the raw water through the cationic resins, while this water then flows through the anionic resins. Subsequently, analyses of hardness, alkalinity, silica, iron, conductivity, both of the water treated in the water demineralizer and that treated in the laboratory were carried out and a comparison of the reduction of the properties of the water was made. All this in order to optimize the regeneration process of ion exchange resins by determining the conditions that give us a lower consumption of regenerant and a high final water quality.
