Download or read book Gas Transport in Porous Media written by Clifford K. Ho and published by Springer Science & Business Media. This book was released on 2006-10-07 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: CLIFFORD K. HOAND STEPHEN W. WEBB Sandia National Laboratories, P. O. Box 5800, Albuquerque, NM 87185, USA Gas and vapor transport in porous media occur in a number of important applications includingdryingofindustrialandfoodproducts,oilandgasexploration,environm- tal remediation of contaminated sites, and carbon sequestration. Understanding the fundamental mechanisms and processes of gas and vapor transport in porous media allows models to be used to evaluate and optimize the performance and design of these systems. In this book, gas and vapor are distinguished by their available states at stan- ? dard temperature and pressure (20 C, 101 kPa). If the gas-phase constituent can also exist as a liquid phase at standard temperature and pressure (e. g. , water, ethanol, toluene, trichlorothylene), it is considered a vapor. If the gas-phase constituent is non-condensable at standard temperature and pressure (e. g. , oxygen, carbon di- ide, helium, hydrogen, propane), it is considered a gas. The distinction is important because different processes affect the transport and behavior of gases and vapors in porous media. For example, mechanisms specific to vapors include vapor-pressure lowering and enhanced vapor diffusion, which are caused by the presence of a g- phase constituent interacting with its liquid phase in an unsaturated porous media. In addition, the “heat-pipe” exploits isothermal latent heat exchange during evaporation and condensation to effectively transfer heat in designed and natural systems.

Book Synopsis Computational Transport Phenomena of Fluid-Particle Systems by : Hamid Arastoopour
Download or read book Computational Transport Phenomena of Fluid-Particle Systems written by Hamid Arastoopour and published by Springer. This book was released on 2016-12-25 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concerns the most up-to-date advances in computational transport phenomena (CTP), an emerging tool for the design of gas-solid processes such as fluidized bed systems. The authors examine recent work in kinetic theory and CTP and illustrate gas-solid processes’ many applications in the energy, chemical, pharmaceutical, and food industries. They also discuss the kinetic theory approach in developing constitutive equations for gas-solid flow systems and how it has advanced over the last decade as well as the possibility of obtaining innovative designs for multiphase reactors, such as those needed to capture CO2 from flue gases. Suitable as a concise reference and a textbook supplement for graduate courses, Computational Transport Phenomena of Gas-Solid Systems is ideal for practitioners in industries involved with the design and operation of processes based on fluid/particle mixtures, such as the energy, chemicals, pharmaceuticals, and food processing.

Book excerpt: Over the last decade, circulating fluidization or fast fluidization has developed rapidly, superseding standard bubbling fluidization in many applications; for example, fast fluidization provides a better means forcontrolling emissions from the combustion of high-sulfur fuels and excels when used in boilers in steam plant and power stations. China initiated the study of fast fluidization in the early 1970s. Focusing on the substantial research cultivated in that country, with Kwauk at the leading edge, this latest volume in the Advances in Chemical Engineering Series is written in the context of the international state of the art and addresses some of the most vital issues surrounding this fluidization method."
Book Synopsis Gas-solid Transport and Reaction Via Intervened Evaporating Sprays by : Pengfei He
Download or read book Gas-solid Transport and Reaction Via Intervened Evaporating Sprays written by Pengfei He and published by . This book was released on 2014 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid catalytic cracking (FCC) is a major process used for converting heavy oils to transportation fuels and light olefins. The gas-solid transport with reaction via intervened evaporating sprays in the FCC riser is specially important but complicated, with coupled mechanisms of chemical reaction and heat, momentum and mass transfer among multiple phases (liquid, solid and gas) in the restriction of wall boundary. Recent developments in FCC process models have progressed along two lines. One aims to develop composition-based kinetic models derived from molecular characterization of petroleum fractions while overlooking the hydrodynamic effect on local catalyst to oil ratio (CTO). The other aims to develop computational fluid dynamics (CFD) based models which cost too much on emphasizing flow dynamics yet not suitable for real time on-site monitor/control/optimization in industry. This work shows the efforts in developing an FCC model that strikes a right balance between the kinetics- and CFD-dominated approaches. Specifically, the feed injection zone, with multiple evaporating sprays penetrating throughout the hot gas-solid flow ambient and overlapping among each other, is integrally modeled (with coupling of FCC kinetic reactions) by geometrically cascading sub-models of single across spray and gas-solid transport. An innovative experimental method is proposed to obtain the statistical characteristics of solids wetting and solid-droplet collision probability distributions from spray impingement onto free-fall particles. This feed-zone modeling, quantifying liquid feed trajectory, droplet vaporization, gas-solid transport and vapor cracking, is capable to provide hydrodynamic and pre-cracking inlet conditions for downstream gas-solid transport in the remaining part of riser. A two-zone analytic model for FCC riser, consisting of an entrance zone and a fully developed riser zone, is thus developed. Using a four-lump cracking kinetic model, this work shows that for the first time the commercial data of Derouin et al. (1997, [14]) can be explained and predicted. The success of the prediction reflects an inherent two-zone character of the FCC riser. Inside the entrance zone, cracking intensity is high and changes rapidly, resulting in a sharp rise in VGO conversion. Outside the entrance zone, cracking intensity is low and becomes slowly varying, giving rise to a sluggish increase in conversion. The results show that the two-zone theory is a simple, practical way of capturing the essence of physicochemical phenomena underpinning the FCC process. Further exploitation of this approach is to quantify solid back-flow in gas-solid transportation due to wall restriction. The continuous modeling, which takes into account mechanistic of radial heterogeneity by considering radial mass and momentum balances between the collision-induced diffusion and the turbulent convection of solids, is proposed. Results are partially validated against published experiment data for radial and axial distributions of both solids and gas characteristic properties. Back-flow ratio can be thus predicted quantitatively for further optimization of riser reactor.

Book Synopsis Gas-Solid Reactions by : Julian Szekely
Download or read book Gas-Solid Reactions written by Julian Szekely and published by Elsevier. This book was released on 2012-12-02 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it's based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.
