Abstract
AbstractThe slip velocity, the dispersed‐phase hold‐up, and the characteristic velocities of the phases in a horizontal pulsed extraction column were investigated under no‐mass transfer conditions using four binary systems: kerosene‐water, toluene‐water, n‐butyl acetate‐water, and butanol‐water. The effects of the pulsation intensity, the dispersed‐ and continuous‐phase flow rates, and the interfacial tension on the dispersed‐phase hold‐up and slip velocity of the phases were investigated. Based on the obtained results, a semi‐empirical correlation for estimating the slip velocity and the characteristic velocity was established, which proved to be in good agreement with the experimental findings.
