Material and Energy Balances for Engineers and Environmentalists


Book Description

Material and energy (M&E) balances are fundamental to chemical (process) engineering, environmental engineering and industrial chemistry. This text presents M&E balance calculations in a compact, transparent format accessible to students and professionals in the above fields, and to others who want to quantify the physical progress of our civilization. The text embraces all topics covered in corresponding engineering undergraduate courses and deals with environmental and sustainability issues of current concern to society. The general balance equation is the foundation for a review of relevant science and economics, and hence, for material and energy accounting in batch and continuous chemical processes. The text focuses on SI units, using flowsheets and stream tables in computer spreadsheets to represent practical systems. Worked examples range from simple stoichiometry to modeling multi-unit recycle and unsteady-state processes.




Introduction to Material and Energy Balances


Book Description

A thorough introduction to balance equation concepts. Geared for the course offered to chemical engineering majors in their sophomore year. Develops a framework for the analysis of flowsheet problem information with extensive use of degree-of-freedom analysis. Presents systematic approaches for manual and computer-aided solution of full scale balance problems. Provides a detailed development of the structure, properties, and interrelationships of species and element balances based on the algebraic view of reaction-stoichiometry and the rate of reaction concept.




Unit Operations in Food Processing


Book Description

This long awaited second edition of a popular textbook has a simple and direct approach to the diversity and complexity of food processing. It explains the principles of operations and illustrates them by individual processes.

Mass and Energy Balances


Book Description

This textbook introduces students to mass and energy balances and focuses on basic principles for calculation, design, and optimization as they are applied in industrial processes and equipment. While written primarily for undergraduate programs in chemical, energy, mechanical, and environmental engineering, the book can also be used as a reference by technical staff and design engineers interested who are in, and/or need to have basic knowledge of process engineering calculation. Concepts and techniques presented in this volume are highly relevant within many industrial sectors including manufacturing, oil/gas, green and sustainable energy, and power plant design. Drawing on 15 years of teaching experiences, and with a clear understanding of students' interests, the authors have adopted a very accessible writing style that includes many examples and additional citations to research resources from the literature, referenced at the ends of chapters.

Handbook on Material and Energy Balance Calculations in Metallurgical Processes


Book Description

"This book approaches the subject of material and energy balances from two directions. First, it emphasizes the fundamental principles of the conservation of mass and energy, and the consequences of these two principles. Second it applies the techniques of computational chemistry to materials processing, and introduces new software developed by the author especially for material and heat balances. The third edition reflects the changes in the professional engineer's practice in the last 30 years, reflecting the dramatic shift away from metallurgical engineering and the extractive industry towards materials engineering. A large and growing number of recent graduates are employed in such fields as semiconductor processing, environmental engineering, and the production and processing of advanced and exotic materials for aerospace, electronic and structural applications. The advance in computing power and software for the desktop computer has significantly changed the way engineers make computations, and the biggest change comes from the computational approach used to solve problems. The spreadsheet program Excel is used extensively throughout the text as the main computational "engine" for solving material and energy balance equations, and for statistical analysis of data. The use of Excel and the introduction of the add-in programs enables the study of a range of variables on critical process parameters, and emphasis is placed on multi-device flowsheets with recycle, bypass, and purge streams whose material and heat balance equations were previously too complicated to solve by the normally-used hand calculator. The Excel-based program FlowBal helps the user set up material and heat balance equations for processes with multiple streams and units"--




Urban Climates


Book Description

Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.
