Book Description
Fluidized-bed column is an interesting technique in gas absorption process. It can be operated at high gas and liquid velocities with low pressure drop. In this work, the fluidized-bed composed of light weight spheres of uniform size, special types of gas distributor and liquid distributor were used to perform uniform fluidization at both high and low velocities of liquid and gas. The first part of the experiment concerned with the study of hydrodynamic characteristics of column in which air and water flowed counter-currently. Hydraulic resistance of bed, minimum fluidization velocity, gas hold-up and liquid hold-up were determined. The variable parameters studied were liquid velocity, gas velocity, and bed height. Correlation of various variables in fluidized-bed column was compared with those in the literature. In the second part, mass transfer coefficients of ammonia were studied. Liquid velocity, gas velocity, bed height, and concentration of ammonia gas were used as variable parameters. The results were summarized and also compared with fixed bed absorbers. The values of mass transfer coefficient expressed in term of Sherwood number can be represented as follows: Sh = 7.17 x 109. Fr[superscript 0.495]. ReL[superscript 0.442]. (Dc/Hs)[superscript 0.621].

Book Description
This book gives a practical account of the modern theory of calculation of absorbers for binary and multicomponent physical absorption and absorption with simultaneous chemical reaction. The book consists of two parts: the theory of absorption and the calculation of absorbers. Part I covers basic knowledge on diffusion and the theory of mass transfer in binary and multicomponent systems. Significant stress is laid on diffusion theory because this forms the basis for the absorption process. In the next chapters the fundamentals of simultaneous mass transfer and chemical reaction, the theory of the desorption of gases from liquids and the formulation of differential mass balances are discussed. Part II is devoted to the calculation of absorbers and the classification of absorbers. The chapters present calculation methods for the basic types of absorber with a detailed analysis of the calculation methods for packed, plate and bubble columns. The authors illustrate the presented material with a large number of examples, starting with simple ones for binary systems and ending with column calculation for multicomponent systems.

Book Description
Absorption and Dispersion of Ultrasonic Waves focuses on the influence of ultrasonics on molecular processes in liquids and gases, including hydrodynamics, energy exchange, and chemical reactions. The book first offers information on the Stokes-Navier equations of hydrodynamics, as well as equations of motion, viscosity, formal introduction of volume viscosity, and linearized wave equation for a nonviscous fluid. The manuscript then ponders on energy exchange between internal and external degrees of freedom as relaxation phenomenon; effect of slow energy exchange on sound propagation; different ways of evaluating the dispersion curve; and exact calculation of absorption and dispersion. The text examines the effects of chemical reactions, thermodynamic theory of relaxation, and mixtures. The book also evaluates the absorption of high intensity sound waves, ratio of relaxation absorption to classical absorption at maximum, and gas mixtures. Discussions also focus on translational relaxation in monatomic gases, linear triatomic molecules, and results for rotational relaxation. The manuscript is a dependable source of data for readers interested in the absorption and dispersion of ultrasonic waves.
