Mechanical and Solid-Fluid Operations

The text presents fundamental principles and analysis of the separation of particulate matter. Analysis and reduction of air pollution involve a variety of technical disciplines. The effective way to control air pollution is to prevent the release of pollutants at the source. The treatment can involve intimately contacting the effluent gases with liquids or solids capable of selectively removing gaseous pollutants or, in the case of particulate contaminants, directing the effluent flow through a device in which the particles are captured on surfaces. This book: Introduces the principle of separation methods of particulate matter (PM), common control equipment of PM, and collection or removal efficiency of the equipment. Describes the concept of separation of particles by sieving/screening, the basic principles of screening equipment, and the screen's effectiveness. Present the fundamental theories of removing particulate and gaseous pollutants from effluent streams by pollution control operations, such as gravitational (gravity chambers) and centrifugal deposition (cyclone separator), electrostatic precipitation, filtration, and wet scrubbing and covers fundamental principles of membrane separation, membrane modules, process design, applications, and governing equations of plate and frame filter press and rotary drum filter. Deals with the basic understanding of reverse osmosis and its theoretical analysis by different total flux and capacity models and explains the basic understanding of adsorption onto the solid surface and their isotherm and kinetics. Includes ancillary material such as numerical problems, review questions, multiple choice questions, and exercises at the end of each chapter. It is primarily written for senior undergraduates, graduate students, and academic researchers in chemical engineering, mechanical engineering, environmental engineering, industrial engineering, manufacturing engineering, and chemistry.
