Book Description
En este trabajo se ha estudiado la influencia de la presión en el equilibrio de fases de sitemas fluidos binarios y fundamentalmente en aquellas regiones del diagrama de fases donde la presión, al aproximar el sistema a un punto o línea crítica, confiere un comportamiento singular a las propiedades termodinámicas. El estudio descansa sobre tres bloque de datos diferentes. -En primer lugar se ha obtenido un conjunto importante de medidas experimentales del equilibrio líquido-líquido de los sistemas H(2)O+C(7)E(5) y C(12)+C(7)E(5) que han permitido discutir la influencia de la presión en el comportamiento de los sistemas ternarios agua + tensioagente no iónico + n-alcano. -En segundo lugar, se ha realizado un análisis de un conjunto de datos de la H(E) del sistema CO(2) + n-hexano + tolueno a distintas presiones y temperaturas. Estos datos, tomados de la ...

Book Description
Laurence Belfiore’s unique treatment meshes two mainstream subject areas in chemical engineering: transport phenomena and chemical reactor design. Expressly intended as an extension of Bird, Stewart, and Lightfoot’s classic Transport Phenomena, and Froment and Bischoff’s Chemical Reactor Analysis and Design, Second Edition, Belfiore’s unprecedented text explores the synthesis of these two disciplines in a manner the upper undergraduate or graduate reader can readily grasp. Transport Phenomena for Chemical Reactor Design approaches the design of chemical reactors from microscopic heat and mass transfer principles. It includes simultaneous consideration of kinetics and heat transfer, both critical to the performance of real chemical reactors. Complementary topics in transport phenomena and thermodynamics that provide support for chemical reactor analysis are covered, including: Fluid dynamics in the creeping and potential flow regimes around solid spheres and gas bubbles The corresponding mass transfer problems that employ velocity profiles, derived in the book’s fluid dynamics chapter, to calculate interphase heat and mass transfer coefficients Heat capacities of ideal gases via statistical thermodynamics to calculate Prandtl numbers Thermodynamic stability criteria for homogeneous mixtures that reveal that binary molecular diffusion coefficients must be positive In addition to its comprehensive treatment, the text also contains 484 problems and ninety-six detailed solutions to assist in the exploration of the subject. Graduate and advanced undergraduate chemical engineering students, professors, and researchers will appreciate the vision, innovation, and practical application of Laurence Belfiore’s Transport Phenomena for Chemical Reactor Design.

Book Description
This book offers a comprehensive picture of nonequilibrium phenomena in nanoscale systems. Written by internationally recognized experts in the field, this book strikes a balance between theory and experiment, and includes in-depth introductions to nonequilibrium fluctuation relations, nonlinear dynamics and transport, single molecule experiments, and molecular diffusion in nanopores. The authors explore the application of these concepts to nano- and biosystems by cross-linking key methods and ideas from nonequilibrium statistical physics, thermodynamics, stochastic theory, and dynamical systems. By providing an up-to-date survey of small systems physics, the text serves as both a valuable reference for experienced researchers and as an ideal starting point for graduate-level students entering this newly emerging research field.

Book Description
Separation Process Essentials provides an interactive approach for students to learn the main separation processes (distillation, absorption, stripping, and solvent extraction) using material and energy balances with equilibrium relationships, while referring readers to other more complete works when needed. Membrane separations are included as an example of non-equilibrium processes. This book reviews and builds on material learned in the first chemical engineering courses such as Material and Energy Balances and Thermodynamics as applied to separations. It relies heavily on example problems, including completely worked and explained problems followed by "Try This At Home" guided examples. Most examples have accompanying downloadable Excel spreadsheet simulations. The book also offers a complementary website, http://separationsbook.com, with supplementary material such as links to YouTube tutorials, practice problems, and the Excel simulations. This book is aimed at second and third year undergraduate students in Chemical engineering, as well as professionals in the field of Chemical engineering, and can be used for a one semester course in separation processes and unit operations.

Book Description
The increasing interest in graphene, due to its unique properties and potential applications, is sparking intense research into chemically derived graphene. This book provides a comprehensive overview of the recent and state-of-the-art research on chemically derived graphene materials for different applications. Starting with a brief introduction on chemically derived graphene, subsequent chapters look at various fascinating applications such as electrode materials for fuel cells, Li/Na-ion batteries, metal–air batteries and Li-S batteries, photocatalysts for degradation of pollutants and solar-to-fuels conversion, biosensing platforms, and anti-corrosion coatings. The emphasis throughout this book is on experimental studies and the unique aspects of chemically derived graphene in these fields, including novel functionalization methods, particular physicochemical properties and consequently enhanced performance. With contributions from key researchers, the book provides a detailed resource on the latest progress and the future directions of chemically derived graphene for students and researchers across materials science, chemistry, nanoengineering and related fields.

Book Description
The book offers a comprehensive report on the design and optimization of a thermochemical heat storage system for use in buildings. It combines theoretical and experimental work, with a special emphasis on model-based methods. It describes the numerical modeling of the heat exchanger, which allows recovery of about two thirds of the waste heat from both solar and thermal energy. The book also provides readers with a snapshot of current research on thermochemical storage systems, and an in-depth review of the most important concepts and methods in thermal management modeling. It represents a valuable resource for students, engineers and researchers interested in thermal energy storage processes, as well as for those dealing with modeling and 3D simulations in the field of energy and process engineering.
