Resumo: The present work aims to evaluate the hydrodynamics of a pulsed packed extractor, with an internal diameter of 0.026m and a length of 1.0m, using the liquid butanol-water system. Thus, the basic parameters obtained for the hydrodynamic study of the extraction column in question as dispersed phase, slip velocity, characteristic velocity and flooding point. The methodology used in the work consisted of determining the holdup fraction of the dispersed phase, obtained through tests of simultaneous interruptions in the column feedings. The effects of frequency pulsation, dispersed phase flow rate and continuous phase flow rate investigated in the analysis of these parameters. New empirical correlations derived from the predictions of the parameters studied obtained in terms of operating variables and physical properties of the liquid system involved. The average absolute value of the relative error (AARE) was always below 5.6%. Good agreement between calculated and experimental results observed for all investigated operating conditions.

Asi, los parámetros básicos obtenidos para el estúdio hidrodinámico  de la coluna de extracción, como la fase dispersa, la velocidade de deslizamento, la velocidade característica y el punto de inundación. La metodologia utilizada consistió en determinar la fracción de retención de la fase dispersa, mediante pruebas de interrupciones simultâneas em la alimentación de la columna. Los efectos de la pulsación de frecuencia, el flujo de fase dispersa y fase continua investigados en el análisis de estos parâmetros. Nuevas correlaciones empíricas devivadas fde las predicciones de los parâmetros estudiados, obtenidos em términos de variables operativas y propriedades físicas del sistema líquido involucrado.
