Download or read book Ultrasonic Coal Wash for De Ashing and De Sulfurization written by B. Ambedkar and published by Springer Science & Business Media. This book was released on 2012-01-03 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focuses on the physical aspects of ultrasonic de-ashing and de-sulfurization, such as cavitation, streaming and their combined effects. Ambedkar Balraj proposes an ultrasound-assisted coal particle breakage mechanism and explores aqueous and solvent-based ultrasonic techniques for de-ashing and de-sulfurization. Ambedkar designs a Taguchi L-27 fractional-factorial matrix to assess the individual effects of key process variables. In this volume he also describes process optimization and scale-up strategies. The author provides a mechanism-based model for ultrasonic reagent-based coal de-sulfurization, proposes a flow diagram for ultrasonic methods of high-throughput coal-wash and discusses the benefits of ultrasonic coal-wash. Coal will continue to be a major fuel source for the foreseeable future and this study helps improve its use by minimising ash and sulfur impurities.

Download or read book Process Intensification written by Ramamurthy Nagarajan and published by CRC Press. This book was released on 2023-04-10 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Process Intensification: Faster, Better, Cheaper presents basic concepts and applications of process intensification (PI) and links their common effects across processes. It defines two fundamental parameters, PI factor, and Cost Impact (CI) factor, and uses these to analyze various applications where Process Intensification has been carried out. Process Intensification principles have, in the past, been applied to diverse fields, ranging from biodiesel production to offshore processing, and this book unifies these aspects to identify the common factors that drive process enhancements. Each chapter investigates a specific application, discusses the key PI principles, and includes problem sets and examples. The book also provides case studies and realworld examples throughout the chapters. Features: Explores Cost Impact of Process Intensification, and their relative magnitudes, as a universal metric Covers a range of industrial applications, including heat and mass transfer, atomization and comminution, and enhanced oil recovery Discusses the application of Process Intensification for clean coal technology and environmental remediation Includes end-of-chapter problems, examples, and case studies The book is intended for senior undergraduate chemical and mechanical engineering students taking courses in Process Design, Process Optimization, Process Synthesis, and Process Intensification. Instructors will be able to utilize a Solutions Manual and Lecture Slides for their course. The eBook+ version includes the following enhancements: Open-ended essay questions to encourage conceptual thinking and apply new information Pop-up explanations of selected concepts and terms throughout the chapters Interactive definition flashcards that summarize key takeaways at the end of the chapter Quizzes within chapters to help readers refresh their knowledge

Download or read book Coal Desulfurization written by S. K. Kawatra and published by Taylor & Francis. This book was released on 2001 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written to provide a comprehensive survey of the current state-of-the-art information in coal preparation, with particular emphasis on coal desulfrization. The primary audience for this book will be practising coal preparation engineers who need complete information about all of the coal preparation and desulphurization technologies that are available now, or that may be available in the future. It will also be valuable for coal researchers who need details and comparative data for cutting-edge technologies that are still under development. The main emphasis is on physical coal preparation, but chapters also include chemical and biological technologies that are under development, but not yet used in industrial practice. Along with the successful technologies, also included are details of processes and techniques that were attempted, but were subsequently abandoned, along with discussions of the reasons they were abandoned.

Download or read book Ultrasound promoted Chemical Desulfurization of Illinois Coals written by and published by . This book was released on 1991 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objectives of the program were to investigate the use of ultrasound to promote coal desulfurization reactions and to evaluate chemical coal desulfurization schemes under mild conditions through a fundamental understanding of their reaction mechanisms and kinetics. The ultimate goal was to develop an economically feasible mild chemical process to reduce the total sulfur content of Illinois Basin Coals, while retaining their original physical characteristics, such as calorific value and volatile matter content. During the program, potential chemical reactions with coal were surveyed under various ultrasonic irradiation conditions for desulfurization, to formulate preliminary reaction pathways, and to select a few of the more promising chemical processes for more extensive study.
