Efficacy of mass transfer coefficient: Multiple pentagonal plate assembly

Abstract

In this study, Mass transfer coefficient was improved using a plurality of pentagonal plates as turbulent promoters in a circular tube. Multi- fluidized beds have a wide range of applications in the processing industry. It is used as a pentagonal plate as a solid, nitrogen as a gas and an electrolyte as a liquid. An apparatus formed by a pentagonal plate promoter arranged concentrically used as an amplification device. The installation of the pentagonal unit has been used to calculate the maximum coefficient of mass transfer. NaOH is used as an electrolytic neutral solution to prepare an equimolar solution of Ferricyanide of potassium and ferrocyanide. The concentration of ions based on volume electrolyte was analyzed using standard permanence solutions and ferri-ferro ions in the iodometric method. The data from substance transfer coefficients are obtained using the diffusion control electrode reaction (Ferricanuro ion reduction). The data transfer coefficients are obtained using current limitation techniques. Compared to single pentagonal plate et al. [17], the maximum enlargement achieved in this study is approximately 30 times. The current research indicates that the variation of the mass axial transfer coefficient is within ± 10%. The mass transfer coefficients increase with the growing speed of the gas surface and the particle size of the promoter. The mass transfer coefficients decrease as the height increases and the characteristic length of the promoter. The liquid apparent speed and the diameter of the accelerator rod significantly affect the mass transfer coefficient.
