Non Thermal Plasma Techniques For Pollution Control Electron Beam And Electrical Discharge Processing

Acid rain, global warming, ozone depletion, and smog are preeminent environmental problems facing the world today. Non-thermal plasma techniques offer an innovative approach to the solution of some of these problems. There are many types of non-thermal plasma devices that have been developed for environmental applications. The potential of these devices for the destruction of pollutants or toxic molecules has already been demonstrated in many contexts, such as nitrogen oxides (NOX) and sulfur dioxide (SO2) in flue gases, heavy metals and volatile organic compounds (VOCs) in industrial effluents, and chemical agents such as nerve gases. This book contains a comprehensive account of the latest developments in non-thermal plasma devices and their applications to the disposal of a wide variety of gaseous pollutants.

Definiert werden die aktuellen Anwendungsmoglichkeiten ionisierender Strahlung zur Losung von Umweltproblemen. Verfa?t wurde dieser Band von uber 100 fuhrenden Wissenschaftlern aus aller Welt, die sich mit Entwicklung und Anwendung von ionisierender Strahlungstechnik im Zusammenhang mit Umweltproblemen beschaftigen. Das einzige Buch, das sich mit der Anwendung ionisierender Strahlung im Umweltbereich beschaftigt. (09/98)

Many books have been written on hazardous waste and nuclear waste separately, but none have combined the two subjects into one single-volume resource. Hazardous and Radioactive Waste Treatment Technologies Handbook covers the technologies, characteristics, and regulation of both hazardous chemical wastes and radioactive wastes. It provides an overview of recent waste technologies. A reference for scientists and engineers, the handbook focuses on waste-related thermal and non-thermal technologies, separation techniques, and stabilization technologies. It includes information on the DOE and DOD waste matrix located at various sites. It reveals current R&D activities in each technology and what improvements can be made in the future. A detailed schematic diagram illustrates each technology so that the process can be explicitly understood. In addition, the handbook covers relative life-cycle cost estimates for treatment systems using various technologies. With contributions from an international panel and extensively peer-reviewed, Hazardous and Radioactive Waste Treatment Technologies Handbook provides the latest information on waste remediation technologies and related regulations. Often in the field you will encounter more than one type of hazardous waste. This handbook gives you the design information you need to decide which technology to use and how to design the equipment for your particular needs. You can then incorporate appropriate technologies into a mixed waste treatment system.

Molecular Physics and Hypersonic Flows bridges the gap between the fluid dynamics and molecular physics communities, emphasizing the role played by elementary processes in hypersonic flows. In particular, the work is primarily dedicated to filling the gap between microscopic and macroscopic treatments of the source terms to be inserted in the fluid dynamics codes. The first part of the book describes the molecular dynamics of elementary processes both in the gas phase and in the interaction with surfaces by using quantum mechanical and phenomenological approaches. A second group of contributions describes thermodynamics and transport properties of air components, with special attention to the transport of internal energy. A series of papers is devoted to the experimental and theoretical study of the flow of partially ionized gases. Subsequent contributions treat modern computational techniques for 3-D hypersonic flow. Non-equilibrium vibrational kinetics are then described, together with the coupling of vibration-dissociation processes as they affect hypersonic flows. Special emphasis is given to the interfacing of non-equilibrium models with computational fluid dynamics methods. Finally, the last part of the book deals with the application of direct Monte Carlo methods in describing rarefied flows.

The links between air pollutants and health impacts are many and complex. The environmental health community is being challenged to take stronger mitigation to respect population health and is taking opportunities to further their implication. Recognizing, observing, and analyzing exposures are a promising way forward, but also raise a myriad of new challenges and questions, including what such approaches are, when and how they can put into practice, and what their implications are for protecting human health. This book gives an overview of key issues in air pollution. Reviews and research papers describe air pollution in a variety of context, such as: evolution of air pollutant, urban structure effects, exposure in agriculture, surface ozone monitoring, the respiratory diseases impacts, appropriate technology, and response management to the air pollution.

Although the climate of the Earth is continually changing from the very beginning, anthropogenic effects, the pollution of the air by combustion and industrial activities make it change so quickly that the adaptation is very difficult for all living organisms. Researcher's role is to make this adaptation easier, to prepare humankind to the new circumstances and challenges, to trace and predict the effects and, if possible, even decrease the harmfulness of these changes. In this book we provide an interdisciplinary collection of new studies and findings on the score of air pollution.

This book provides a comprehensive overview of the field of plasma catalysis, regarded as a promising alternative to thermal processes for energy and environmental applications. It bridges the gap between the plasma and catalysis research communities, covering both the fundamentals of plasma catalysis and its application in environmental and energy research. The first section of the book offers a broad introduction to plasma catalysis, covering plasma-catalyst systems, interactions, and modeling. The core of the book then focuses on different applications, describing a wide range of plasma-catalytic processes in catalyst synthesis, environmental clean-up, greenhouse gas conversion and synthesis of materials for energy applications. Chapters cover topics ranging from removal of NOx and VOCs to conversion of methane, carbon dioxide and the reforming of ethanol and methanol. Written by a group of world-leading researchers active in the field, the book forms a valuable resource for scientists, engineers and students with different research backgrounds including plasma physics, plasma chemistry, catalysis, energy, environmental engineering, electrical engineering and material engineering.
