Available in PDF, EPUB and Kindle. Book excerpt: Les préoccupations environnementales incitent industriels et scientifiques à des efforts constants afin de limiter les émissions de polluants à l'atmosphère. Une bonne connaissance des mécanismes chimiques impliqués aussi bien dans les processus de formation de ces polluants, que dans les procédés contribuant à leur réduction est une étape nécessaire au contrôle des émissions polluantes. Les travaux présentés dans ce mémoire entrent dans ce cadre, en focalisant plus particulièrement l'attention sur les oxydes d'azote (NOx) et les Composés Organiques Volatils Oxygénés (COVO). La maîtrise des mécanismes gérant les procédés de formation et de réduction des principaux polluants nécessite la mise en oeuvre de dispositifs expérimentaux adaptés et associés à des méthodes analytiques performantes. Ces études menées à l'échelle du laboratoire ont pour principal objectif l'établissement de bases de données expérimentales, suffisamment étoffées pour élaborer, valider ou optimiser un modèle cinétique. Un compromis doit nécessairement être trouvé entre la nature des informations expérimentales que l'on souhaite obtenir et la méthode analytique à mettre en œuvre. Les travaux menés sur les mécanismes de formation et de réduction des NOx, ainsi que sur les procédés de dégradation thermique des COVO, nous ont permis de mettre en place différentes stratégies expérimentales. Il est notamment fondamental d'obtenir des informations précises sur des espèces réactives souvent présentes à l'état de traces dans le milieu réactionnel.

This book was released on 1997 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compte tenu de leur impact sur l'environnement, l'émission de polluants tels que la monoxyde de carbone (CO) ou les oxydes d'azote (NOx) fait l'objet de normes sévères. Ces normes sont un enjeu important pour les entreprises fabriquant des brûleurs destinés à la production d'eau chaude domestique. Ces entreprises doivent modifier leurs systèmes ou en étudier de nouveaux pour pouvoir répondre à ces normes. Ces études empiriques coûtent cher et l'utilisation de moyens de simulation numérique permet de réduire les coûts. Le but du présent travail est de développer un code de calcul permettant la simulations de la combustion dans les chaudières domestiques. Ce code de calcul est basé sur le concept de l'assemblage de réacteurs homogènes. Il permet la prise en compte d'une cinétique chimique complexe et des transferts de chaleur convectif et radiatif. Il a été validé grâce à des mesures réalisées dans un foyer aussi proche que possible de la configuration réelle. Il a donc fallu mettre au point une installation expérimentale permettant la mesure de champs de vitesse et de concentration chimique dans un foyer. Après comparaison avec les résultats expérimentaux, ce code de calcul a été utilisé afin de prédire le comportement du système réel face à des modifications des conditions de fonctionnement. Les tendances reproduites sont conformes à la réalité

Available in PDF, EPUB and Kindle. Book excerpt: With a population of more than eighteen million people, Mexico City is a major metropolitan area where the effects of urban development on air quality are of immediate concern. Air pollution exposures and effects on forests in the Mexico City Air Basin are in many respects similar to those reported in the Los Angeles, California Air Basin. Studies of air pollution impacts on forests in these two regions may serve as models for urban areas all over the world. Although scientists have studied air pollution and its effects on forests and vegetation in the Mexico City Air Basin for years, this book reviews and synthesizes this body of work for the first time. This synthesis is particularly valuable as air pollution increases at an alarming rate along with global urbanization. A thorough discussion of regional geology, climate and hydrology, historical natural resource utilization, and sociological factors provide the context for evaluating air pollution impacts on the highly valued forests surrounding this megacity. The environmental and ecological consequences of chronic exposure to biologically important pollutants are considered in various case studies. Finally, the editors discuss the state of air pollution research in the Mexico City Air Basin and the outlook for the health and sustainability of forests within the Basin.

This book was released on 1992-02-01 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution in the lower atmosphere, or troposphere, threatens the health of humans, animals, and vegetation. This book discusses how scientific information can be used to develop more effective regulations to control ozone. Rethinking the Ozone Problem in Urban and Regional Air Pollution discusses: The latest data and analysis on how tropospheric ozone is formed. How well our measurement techniques are functioning. Deficiencies in efforts to date to control the problem. Approaches to reducing ozone precursor emissions that hold the most promise. What additional research is needed. With a wealth of technical information, the book discusses atmospheric chemistry, the role of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in ozone formation, monitoring and modeling the formation and transport processes, and the potential contribution of alternative fuels to solving the tropospheric ozone problem. The committee discusses criteria for designing more effective ozone control efforts. Because of its direct bearing on decisions to be made under the Clean Air Act, this book should be of great interest to environmental advocates, industry, and the regulatory community as well as scientists, faculty, and students.

Available in PDF, EPUB and Kindle. Book excerpt: Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. The formation of gaseous and particulate secondary products caused by oxidation of VOCs is one of the largest unknowns in the quantitative prediction of the earth’s climate on a regional and global scale, and on the understanding of local air quality. To be able to model and control their impact, it is essential to understand the sources of VOCs, their distribution in the atmosphere and the chemical transformations which remove these compounds from the atmosphere. In recent years techniques for the analysis of organic compounds in the atmosphere have been developed to increase the spectrum of detectable compounds and their detection limits. New methods have been introduced to increase the time resolution of those measurements and to resolve more complex mixtures of organic compounds. Volatile Organic Compounds in the Atmosphere describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyse gaseous and particulate organic compounds in the atmosphere. The aim is to provide an authoritative review to address the needs of both graduate students and active researchers in the field of atmospheric chemistry research.
