Book excerpt: The hydrodynamics of three-phase (gas-liquid-solid) fluidized beds has been studied in two columns with inside diameters of 7.62 and 15.2 cm respectively. The minimum gas and liquid velocities necessary to fluidize various types of solids were determined and correlated as a function of the particle size and density and the liquid viscosity; no effect of the initial bed height or column diameter was found. Overall phase holdups, or volume fractions, determined from a homogeneous bed model were combined with similar literature data to yield correlations for the overall gas and solid phase holdups. The overall gas holdup increased as the gas velocity was increased, while the overall solid holdup was decreased by increased liquid velocity and was increased by increased particle diameter or solid/liquid density difference. An electroconductivity technique was developed for use in the three-phase fluidized beds which allowed each of the phase holdups to be determined at any point in the column. The technique has shown the existence of a transition region as the bed goes from a three-phase to a two-phase system. The holdup profiles were fitted using the error function, and the mean and standard deviation of the solid holdup profile, along with the gas and solid holdups in the regions where they were constant, were measured for each set of run conditions. Use of these five parameters, which were correlated with the physical pxrameters of the systems studied, permits each of the three phase holdup profiles to be predicted. This gives the reactor designer more information concerning phase distributions than was available previously; thus it will aid in the design of reactors where local conditions throughout the bed must be considered.

Book excerpt: The general purpose of the experimental investigations described here has to study the hydrodynamic properties of gas-liquid fluidized beds. Gas -liquid fluidization of or three-phase fluidization is a chemical engineering operation where all the three phases are brought into contact with each other. This contact is brought about by passing the gas and liquid trough the bed of solids. The solids are said to be in a fluidized state when they are suspended in the continuous phase.Hydrodynamic properties such as gas hold-up, liquid hold-up and bed porosity have been studied. These properties depend upon certain independent variables such as gas flow rates, liquid flow rate, particle size, static bed heights, gas density, liquid density, solid density, liquid surface tension, liquid viscosity, gas viscosity and particle shape. During the course of this experimental investigation only four of these parameters have been varied, viz, gas flow rates, liquid flow rates, static bed height and particle size.The result of these experimental investigations is discussed and correlations have also been developed for the hydrodynamics properties studied.

Book excerpt: The hydrodynamics of three-phase (gas-liquid-solid) fluidized beds has been studied in two columns of 7.62 and 15.2 cm in dia. The minimum gas and liquid velocities necessary to fluidize a bed were determined as a function of the particle size and density and the liquid viscosity; no effect of the initial bed height or column diameter was found. An electroconductivity technique was used to measure local concentrations of solid, liquid, and gas in the fluidized bed; these profiles were fitted using the error function. Overall solid holdup data were combined with over 1350 points from the literature to yield a dimensional correlation involving the physical parameters of the systems studied.
