The Chemical Engineer's Practical Guide to Fluid Mechanics: Now Includes COMSOL Multiphysics 5 Since most chemical processing applications are conducted either partially or totally in the fluid phase, chemical engineers need mastery of fluid mechanics. Such knowledge is especially valuable in the biochemical, chemical, energy, fermentation, materials, mining, petroleum, pharmaceuticals, polymer, and waste-processing industries. Fluid Mechanics for Chemical Engineers: with Microfluidics, CFD, and COMSOL Multiphysics 5, Third Edition, systematically introduces fluid mechanics from the perspective of the chemical engineer who must understand actual physical behavior and solve real-world problems. Building on the book that earned Choice Magazine's Outstanding Academic Title award, this edition also thoroughly introduces the popular COMSOL Multiphysics 5 software. This third edition contains extensive coverage of both microfluidics and computational fluid dynamics, systematically demonstrating CFD through detailed examples using COMSOL Multiphysics 5 and ANSYS Fluent. The chapter on turbulence now presents valuable CFD techniques to investigate practical situations such as turbulent mixing and recirculating flows. Part I offers a clear, succinct, easy-to-follow introduction to macroscopic fluid mechanics, including physical properties; hydrostatics; basic rate laws; and fundamental principles of flow through equipment. Part II turns to microscopic fluid mechanics. Differential equations of fluid mechanicsViscous-flow problems, some including polymer processingLaplace's equation, irrotational, and porous-media flowsNearly unidirectional flows, from boundary layers to lubrication, calendering, and thin-film applicationsTurbulent flows, showing how the k/ε method extends conventional mixing-length theoryBubble motion, two-phase flow, and fluidizationNon-Newtonian fluids, including inelastic and viscoelastic fluidsMicrofluidics and electrokinetic flow effects including electroosmosis, electrophoresis, streaming potentials, and electroosmotic switchingComputational fluid mechanics with ANSYS Fluent and COMSOL Multiphysics Nearly 100 completely worked practical examples include ten new COMSOL 5 examples: boundary layer flow, non-Newtonian flow, jet flow, lathe flow, lubrication, momentum diffusion, turbulent flow, and others. More than 300 end-of-chapter problems of varying complexity are presented, including several from University of Cambridge exams. The author covers all material needed for the fluid mechanics portion of the professional engineer's exam.

The methodologies and technologies adaptable to process chemistry are the focus of this unique book, as new catalysts, reactions, and methods for the synthesis of functional materials are dealt with in depth for the first time. Those materials take in pharmaceuticals, agrochemicals, functional materials, chemical raw materials, and other substances in the field of process chemistry including green chemistry. Process chemistry underpins the competitiveness of chemical and pharmaceutical industries, but its stagnation is estimated to cause industrial depression and excessive loss. For that reason, chemists focus on process chemistry consistently so that the development of novel and efficient new reactions and technologies provides an essential stimulus. In addition, this volume describes the important development of selected new synthetic devices for process development and the process design for a larger scale, thus furnishing a valuable source for all who are engaged in process chemistry.

The book allows the reader to: (i) Get a solid grasp of under-the-hood mathematical results (ii) Develop models of sophisticated processes (iii) Transform models to different geometries and domains as appropriate (iv) Utilize various model simplification techniques (v) Learn simple and effective computational methods for model simulation (vi) Intensify the effectiveness of their research Modeling and Simulation for Chemical Engineers: Theory and Practice begins with an introduction to the terminology of process modeling and simulation. Chapters 2 and 3 cover fundamental and constitutive relations, while Chapter 4 on model formulation builds on these relations. Chapters 5 and 6 introduce the advanced techniques of model transformation and simplification. Chapter 7 deals with model simulation, and the final chapter reviews important mathematical concepts. Presented in a methodical, systematic way, this book is suitable as a self-study guide or as a graduate reference, and includes examples, schematics and diagrams to enrich understanding. End of chapter problems with solutions and computer software available online at www.wiley.com/go/upreti/pms-for-chemical-engineers are designed to further stimulate readers to apply the newly learned concepts.

This book provides state-of-the-art reviews, the latest research, prospects and challenges of the production of platform chemicals such as C6 sugars, 5-hydroxymethylfurfural, furfural, gamma-valerolactone, xylitol, 2,5-furandicarboxylic acid, levulinic acid, ethanol and others from sustainable biomass resources using processes that include heterogeneous catalysis, ionic liquids, hydrothermal/solvothermal, electrochemical and fermentation methods. It also discusses the application of these chemicals and their derivatives for synthesizing commodity chemicals via various routes. Intended as a reference resource for researchers, academicians and industrialists in the area of energy, chemical engineering and biomass conversion, it provides a wealth of information essential for assessing the production and application of various biomass-derived platform chemicals using biological, chemical and electrochemical techniques.

The Center for Chemical Process Safety International Conference (CCPS) is one of four parallel symposia that comprise The Global Congress on Process Safety (GCPS). Organized by volunteers from industry and academia, the CCPS conference promotes process safety by identifying emerging process safety issues and advancing leading process safety management practices. It is dedicated to managing process safety systematically, locally, regionally and internationally. The conference agenda will consist of nine sessions, each with three 25-minute presentations. Papers are selected by session chairs based on an abstract of 100-200 words. The abstract must offer a brief account of the contents, conclusions, and the relevance to the topic area. Submitted abstracts must include the author, their affiliation, full address, email, and phone number. The papers will be published in the GCPS proceedings. Abstracts will be submitted online, by October 15, 2015.

This conference will be the 50th Anniversary of the Loss Prevention Symposium (LPS). LPS is one of four parallel symposia that comprise The Global Congress on Process Safety (GCPS). The purpose of the LPS conference is to aid in the prevention of serious loss incidents that involve fires, explosions, runaway reactions, and major material releases in the chemical, petrochemical, and related industries. The conference agenda will consist of eleven sessions, each with three 25-minute presentations. Papers are selected by session chairs based on an abstract of 100-200 words. The abstract must offer a brief account of the contents, conclusions, and the relevance to the topic area. Submitted abstracts must include the author, their affiliation, full address, email, and phone number. The papers will be published in the GCPS proceedings. Abstracts will need to be submitted online, by October 15, 2015.

The Mission and Purpose of the Process Safety Management Mentoring (PSM2) Forum at the Global Congress of Process Safety is to provide those new to the field with the basics of Process Safety Management (PSM). This track is aimed at young engineers, professionals new to the field, and those interested in strengthening the fundamentals of PSM. The content of the track is balanced between tutorial material, lessons learned, and panel discussions. The framework for the track relies upon the CCPS's 20 elements of risk-based process safety. The introductory and basic content of the PSM2 track is complemented by the advanced topics and discussions in the other three symposia of the Global Congress.
