Available in PDF, EPUB and Kindle. Book excerpt: Réduire et contrôler les émissions de gaz à effet de serre générés par les activités industrielles, tel que le CO2, est un enjeu majeur. Afin de limiter ces rejets, une des solutions développées est le captage en postcombustion utilisant une solution aqueuse d'amine. A l'heure actuelle, l'amine de référence est la Monoethanolamine (MEA). Cependant, la forte énergie de régénération requise est unhandicap à son utilisation industrielle. Il est donc nécessaire de trouver de nouvelles structuresd'amines ayant des propriétés thermodynamiques plus favorables.L'objectif de la thèse est d'établir une relation entre la structure des amines et leurs propriétés thermodynamiques afin d'apporter une compréhension générale. Devant le nombre conséquent destructures possibles, des données sont obtenues via l'utilisation d'une expérimentation à haut débit (E.H.D.). Par l'utilisation d'une nouvelle représentation permettant d'étudier les mono- et multiamines et de la dérivée des isothermes d'absorption, nous avons mis en évidence deux grandes familles: la famille Aet la famille B qui a un comportement atypique non mis en évidence dans la littérature. Ces résultatsont permis d'orienter nos travaux afin d'obtenir un modèle général pour chacune de ces deux familles afin de déterminer des données thermodynamiques à partir des isothermes d'absorption (famille A:pKa*, pKc*, capacité cyclique - famille B: pKaIII, pKcI, capacité cyclique). Ces données thermodynamiques ont ensuite permis d'établir une série de relations structure/propriétés et d'identifier les caractéristiques structurales d'amines potentiellement performantes pour le captage du CO2.
Book Synopsis Etude thermodynamique de solutions aqueuses d'amines démixantes pour le captage du dioxyde de carbone by : Yohann Coulier
Download or read book Etude thermodynamique de solutions aqueuses d'amines démixantes pour le captage du dioxyde de carbone written by Yohann Coulier and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette thèse est l'étude thermodynamique des systèmes {amine - eau} et {CO2 - amine - eau}. Les amines étudiées sont des amines démixantes qui ont la particularité de présenter une séparation de phase liquide-liquide en solution aqueuse en fonction de la température et du taux de charge en CO2. Ces composés sont considérés comme de nouveaux solvants potentiels pour le captage du CO2. Les séparations de phase liquide- liquide des systèmes {amine - eau} ont été mises en évidence par calorimétrie et par une technique visuelle en utilisant un microcalorimètre (microDSCIII, Setaram) et une cellule d'équilibre de phase (SPM20, Thar Technologies). Pour permettre la représentation thermodynamique des systèmes {amine - eau}, les volumes molaires d'excès, les enthalpies molaires d'excès et les capacités calorifiques spécifiques ont été mesurés. Les enthalpies de mélange ont été déterminées avec une technique calorimétrique à écoulement. Le calorimètre employé est un BT2.15 de chez Setaram équipé avec une cellule de mélange développée au laboratoire. Les volumes molaires d'excès on été déterminés à partir des mesures des masses volumiques obtenues avec un densimètre à tube vibrant. Les capacités calorifiques spécifiques ont été déterminées avec le microcalorimètre microDSCIII. Les enthalpies d'absorption du CO2 dans les solutions aqueuses et les limites de solubilité ont été étudiées pour les amines présentant un intérêt pour le captage du CO2 avec une technique calorimétrique à écoulement utilisant un C80 de chez Setaram. La dernière partie de ce travail concerne le développement de modèle thermodynamique pour corréler les données mesurées. Les énergies de Gibbs des systèmes {amine - eau} sont calculées en utilisant soit le modèle étendu UNIQUAC soit le modèle NRTL. Cependant, deux sets de paramètres ont été obtenus pour décrire d'une part les équilibres liquide-liquide et d'autre part, les enthalpies molaires d'excès et les capacités calorifique spécifiques. Pour les systèmes {CO2 - amine - eau}, un modèle gamma-phi a été utilisé. Les paramètres d'interaction ont été ajustés à partir de données d'équilibre liquide vapeur et permettent de prédire les enthalpies de solutions, les limites de solubilités et la spéciation du système en fonction du taux de charge.

Book Synopsis Extrusion in Ceramics by : Frank Händle
Download or read book Extrusion in Ceramics written by Frank Händle and published by Springer Science & Business Media. This book was released on 2009-08-12 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frank Handle ̈ 1.1 What to Expect For some time now, I have been toying around with the idea of writing a book about “Ceramic Extrusion”, because to my amazement I have been unable to locate a single existing, comprehensive rundown on the subject – much in contrast to, say, plastic extrusion and despite the fact that there are some outstanding contributions to be found about certain, individual topics, such as those in textbooks by Reed [1], Krause [2], Bender/Handle ̈ [3] et al. By way of analogy to Woody Allen’s wonderfully ironic movie entitled “Eve- thing You Always Wanted to Know about Sex”, I originally intended to call this book “Everything You Always Wanted to Know about Ceramic Extrusion”, but - ter giving it some extra thought, I eventually decided on a somewhat soberer title. Nevertheless, my companion writers and I have done our best – considering our target group and their motives – not to revert to the kind of jargon that people use when they think the less understandable it sounds, the more scienti c it appears. This book addresses all those who are looking for a lot or a little general or selective information about ceramic extrusion and its sundry aspects. We realize that most of our readers will not be perusing this book just for fun or out of intellectual curiosity, but because they hope to get some use out of it for their own endeavours.

Book Synopsis New Perspectives on Mineral Nucleation and Growth by : Alexander E.S. Van Driessche
Download or read book New Perspectives on Mineral Nucleation and Growth written by Alexander E.S. Van Driessche and published by Springer. This book was released on 2017-01-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, numerous studies have demonstrated the existence of alternative pathways to nucleation and crystallisation that oppose the classical view. Such proposed scenarios include multistage reactions proceeding via various precursor species and/or intermediate phases. The aim of this book is to review and discuss these recent advances in our understanding of the early stages of mineralisation through a series of contributions that address both experimental and theoretical studies about the formation and nature of initial precursor species (e.g., prenucleation clusters, dense liquid phases, amorphous nanoparticles, etc.) as well as their transformations leading to the stable mineral phase. Several chapters are devoted to cutting-edge analytical techniques used for investigating the above processes in situ, in real time and at conditions relevant to both natural and industrial processes. At the end of the book, the editors summarize the key questions that still need to be addressed in order to establish a complete picture of the nucleation and growth processes involved during the formation of minerals

Book Synopsis Environmental Barrier Coatings by : Kang N. Lee
Download or read book Environmental Barrier Coatings written by Kang N. Lee and published by MDPI. This book was released on 2020-12-29 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global increase in air travel will require commercial vehicles to be more efficient than ever before. Advanced engine hot section materials are a key technology required to keep fuel consumption and emission to a minimum in next-generation gas turbines. Ceramic matrix composites (CMCs) are the most promising material to revolutionize gas turbine hot section materials technology because of their excellent high‐temperature properties. Rapid surface recession due to volatilization by water vapor is the Achilles heel of CMCs. Environmental barrier coatings (EBCs) is an enabling technology for CMCs, since it protects CMCs from water vapor. The first CMC component entered into service in 2016 in a commercial engine, and more CMC components are scheduled to follow within the next few years. One of the most difficult challenges to CMC components is EBC durability, because failure of EBC leads to a rapid reduction in CMC component life. Key contributors to EBC failure include recession, oxidation, degradation by calcium‐aluminum‐magnesium silicates (CMAS) deposits, thermal and thermo‐mechanical strains, particle erosion, and foreign object damage (FOD). Novel EBC chemistries, creative EBC designs, and robust processes are required to meet EBC durability challenges. Engine-relevant testing, characterization, and lifing methods need to be developed to improve EBC reliability. The aim of this Special Issue is to present recent advances in EBC technology to address these issues. In particular, topics of interest include but are not limited to the following: • Novel EBC chemistries and designs; • Processing including plasma spray, suspension plasma spray, solution precursor plasma spray, slurry process, PS-PVD, EB-PVD, and CVD; • Testing, characterization, and modeling; • Lifing.
Book Synopsis Wine and Tourism by : Marta Peris-Ortiz
Download or read book Wine and Tourism written by Marta Peris-Ortiz and published by Springer. This book was released on 2015-12-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to show how wine tourism can be used as a model for sustainable economic development, driving economic growth and social development in some locations. It will explore the interaction between tourism and viticulture in wine tourism destinations, while also explaining some of the repercussions of these activities. This book covers various topics including regional development, environmental management, sustainable viticulture, quality management in wineries and wine tourism routes among others. Wine tourism, which combines two important yet distinct economic activities (i.e., tourism and viticulture), has recently emerged as a new tourism product driven by tourists’ search for new experiences and wineries’ need to diversify their businesses and seek new revenue streams to boost sales. This new form of tourism, which typically takes place in rural areas and which combines wine production with tourist activities, is becoming important for such regions by providing a complementary income source. It provides a model for sustainable economic development for these regions, which for various reasons may otherwise struggle to develop. Featuring cases and business implications from various locations, this book provides an important source of knowledge—both theoretical and practical—suitable to academics, scholars, researchers, and practitioners in the tourism sector and the wine industry.

Book Synopsis Lessons from Amazonia by : Richard O. Bierregaard
Download or read book Lessons from Amazonia written by Richard O. Bierregaard and published by Yale University Press. This book was released on 2001-12-11 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deforestation is occurring at an alarming rate in many parts of the world, causing destruction of natural habitat and fragmentation of what remains. Nowhere is this problem more pressing than in the Amazon rainforest, which is rapidly vanishing in the face of enormous pressure from humans to exploit it. This book presents the results of the longest-running and most comprehensive study of forest fragmentation ever undertaken, the Biological Dynamics of Forest Fragments Project (BDFFP) in central Amazonia, the only experimental study of tropical forest fragmentation in which baseline data are available before isolation from continuous forest took place.A joint project of Brazil’s National Institute for Research in Amazonia and the U.S. Smithsonian Institution, the BDFFP has investigated the many effects that habitat fragmentation has on plants, invertebrates, and vertebrates. The book provides an overview of the BDFFP, reports on its case studies, looks at forest ecology and tree genetics, and considers what issues are involved in establishing conservation and management guidelines.
