Gas-liquid mass transfer, agitator power consumption, rheology, gas-liquid mixing and gas hold-up have been studied in an agitated, sparged vessel of diameter, T = 0.3 m, with a liquid capacity of 0.02 m\(^3\), unaerated liquid height = 0.3 m. The solutions of sodium carboxymethylcellulose used exhibit moderate viscoelasticity and shear thinning behaviour, obeying the power law over the range of shear rates studied. The gas-liquid mass transfer was studied using a steady state technique. This involves monitoring the gas and liquid phase oxygen concentrations when a microorganism (yeast) is cultured in the solutions of interest. Agitator power consumption was measured using strain gauges mounted on the impeller shaft. Various agitator geometries were used. These were: Rushton turbines (D = T/3 and D = T/2), used singly and in pairs; Intermig impellers (D = 0.58T), used as a pair; and a 45° pitched blade turbine (D = T/2), used in combination with a Rushton turbine. Gas hold-up and gas-liquid flow patterns were visually observed. In addition, the state of the culture variables, (oxygen uptake rate and carbon dioxide production rate), were used to provide a respiratory quotient, the value of which can be linked to the degree of gas-liquid mixing in the vessel. Measurement of point values of the liquid phase oxygen concentration is also used to indicate the degree of liquid mixing attained. The volumetric mass transfer coefficient, k\(_L\)a, was found to be dependent on the conditions in which the yeast was cultivated, as well as being a function of time. These variations were associated with variations in solution composition seen over the course of each experiment. Steps were taken to ensure that further k\(_L\)a values were measured under identical conditions of the culture variables, in order to determine the effect on k\(_L\)a of varying viscosity, agitator speed and type and air flow rate. Increasing solution viscosity results in poorer gas-liquid mixing and.

Mixing: Theory and Practice, Volume III is a five-chapter text that covers the significant improvements in the theoretical aspects and knowledge in mixing related to industrial-scale operations. The introductory chapters deal with the agitation of particulate solid-liquid mixtures and the turbulent radial mixing in pipes, with particular emphasis on the effects of jets and baffles on such mixing. The following chapter presents the theoretical analysis and experimental confirmation for predicting hydrodynamic characteristics and some process results in mechanically agitated vessels. Another chapter provides a comprehensive development of approaches and recommended practices for scale-up of agitated liquid equipment. The methods considered serve as a useful guide for reducing the risk of scale-up and scale-down catastrophes. The last chapter discusses the fundamental concepts and measures of the quality of mixing and the mechanisms of mixing and segregation. This chapter also introduces the process of continuous mixing of solids.

This book is written primarily for an audience of engineers who design, specify, procure, update, and maintain mixers in the processing industries. It is an ap plication-oriented handbook to support the design and operation of mixers for liquids, liquids and solids, liquids and gases, and any combination thereof. This book does not address solids mixing. Mixing applications are identified as either flow controlling or shear rate controlling, and are addressed as such. Specific mixing applications and design parameters are presented for blending, solid suspension, heat transfer, mass transfer, dispersions, extractions, etc. Fundamentals of mixer design and operation, agitation applications spec trum, types and geometries of mixing impellers, etc. are presented in Chapter I, providing the basis for practical information presented in subsequent chap ters. Flow controlled mixing applications are discussed in Chapter 2. These in clude blending, solid suspension, heat transfer, dissolving of solids, and crys tallization. Optimization of mixer design is emphasized, with an eye to saving power and capital cost. Also discussed is the use of draft tube circulator mixers to optimize mixer performance and cost. Shear controlled mixing applications are addressed in Chapter 3. These in clude gas-liquid dispersions, mass transfer, fermentation, emulsions, extrac tions, and dispersions of solids in liquids. Chapter 4 focuses on geometric and nongeometric scaleup of mixers to ac complish equal or better mixing results in various scales of volume. Scaleup relevant to applications of blending, solids suspension, and mass and heat trans fer is explained.
