In the field of waste disposal, recovery, and recycling, industrial residues from ceramic and mining activities are just an assemblage of minerals. So is municipal waste, after removing the organic part in incinerators or after long-time disposal. In almost every case, a natural counterpart is present. Applying what is known from natural systems on waste assemblages is the key to predicting their fate, at a short and long time, and suggesting the best for high-temperature recycling. This book aims to bring the Earth Science community to the edge of waste management, offering background information, the basics of high and low-temperature geochemistry involved, and an overview of waste investigation connected to minerals. This book also addresses mineral tailings, incinerator bottom, fly ashes, metal slags, ceramic industry residue, and eventually sanitary issues. The primary readership will be graduate students and professionals in geological and environmental fields.

This book presents a theoretical analysis of the modern methods used for modeling various chemical engineering processes. Currently, the two primary problems in the chemical industry are the optimal design of new devices and the optimal control of active processes. Both of these problems are often solved by developing new methods of modeling. These methods for modeling specific processes may be different, but in all cases, they bring the mathematical description closer to the real processes by using appropriate experimental data. In this book, the authors detail a new approach for the modeling of chemical processes in column apparatuses. Further, they describe the types of neural networks that have been shown to be effective in solving important chemical engineering problems. Readers are also presented with mathematical models of integrated bioethanol supply chains (IBSC) that achieve improved economic and environmental sustainability. The integration of energy and mass processes is one of the most powerful tools for creating sustainable and energy efficient production systems. This book defines the main approaches for the thermal integration of periodic processes, direct and indirect, and the recent integration of small-scale solar thermal dryers with phase change materials as energy accumulators. An exciting overview of new approaches for the modeling of chemical engineering processes, this book serves as a guide for the important innovations being made in theoretical chemical engineering.

R4,413 R3,478 Discovery Miles 34 780 Save R935 (21%) Ships in 12 - 17 working days

"Fault-Tolerant Process Control" focuses on the development of general, yet practical, methods for the design of advanced fault-tolerant control systems; these ensure an efficient fault detection and a timely response to enhance fault recovery, prevent faults from propagating or developing into total failures, and reduce the risk of safety hazards. To this end, methods are presented for the design of advanced fault-tolerant control systems for chemical processes which explicitly deal with actuator/controller failures and sensor faults and data losses. Specifically, the book puts forward:

.A framework for detection, isolation and diagnosis of actuator and sensor faults for nonlinear systems;

. Controller reconfiguration and safe-parking-based fault-handling methodologies;

. Integrated-data- and model-based fault-detection and isolation and fault-tolerant control methods;

. Methods for handling sensor faults and data losses; and

. Methods for monitoring the performance of low-level PID loops.

The methodologies proposed employ nonlinear systems analysis, Lyapunov techniques, optimization, statistical methods and hybrid systems theory and are predicated upon the idea of integrating fault-detection, local feedback control, and supervisory control. The applicability and performance of the methods are demonstrated through a number of chemical process examples. "Fault-Tolerant Process Control" is a valuable resource for academic researchers, industrial practitioners as well as graduate students pursuing research in this area."

Dry Mineral Processing (Hardcover, 1st ed. 2022): Saeed Chehreh Chelgani, Ali Asimi Neisiani Dry Mineral Processing (Hardcover, 1st ed. 2022)
Saeed Chehreh Chelgani, Ali Asimi Neisiani
R4,361 Discovery Miles 43 610 Ships in 12 - 17 working days

This book introduces and explains all existing dry processing methods, drawing from larges studies about these techniques in both the academia and industrial sectors. Potentially, water insufficiency is one of the critical issues that could be the major cause of international conflicts. Thus, reducing water consumption and pollution in all industrial sectors is an essential issue for all countries. As a main part of the mining industry, ore processing plants are highly dependent on water, and water scarcity poses significant risk to the industry. Thus, water consumption is a strategic issue for mineral processing plants, particularly in dry climate countries. To select dry or wet processing, the differences between these conditions should be taken into consideration, which needs an in-depth understanding of the various possible methods. This book will be of interest to professionals and researchers.

Gold-Catalyzed Cycloisomerization Reactions Through Activation of Alkynes - New Developments and Mechanistic Studies... Gold-Catalyzed Cycloisomerization Reactions Through Activation of Alkynes - New Developments and Mechanistic Studies (Hardcover, 2014 ed.)
Antoine Simonneau
R3,416 Discovery Miles 34 160 Ships in 12 - 17 working days

Antoine Simonneau's thesis highlights the development of new cycloisomerization reactions through the activation of alkynes with gold complexes. First Simonneau describes 1,6-enynes and their direct conversion into allenes through 1,5-hydride or ester migration processes. The author and his team used appropriate propargylic functional groups to achieve this conversion. This study shows that O-tethered 1,6-enynes carrying a strained cycloalkane at the propargylic position could undergo a cyclopropanation/ring expansion cascade reaction. The author employed this rearrangement as the starting point in the design of a new macro cycle synthesis. The next part of the thesis focuses on the cycloisomerization of diynes involving as the first step of the process the rearrangement of one alkyne partner into an allene thanks to a gold-catalyzed 1,3-shift of a propargylic ester. The thesis discloses a new cycloisomerization pattern featuring a 1,5-carbonyl transfer, giving rise to unprecedented cross-conjugated diketones. In the final part of the research, Simmoneau investigates the gold-catalyzed cycloisomerization mechanism of 1,6-enynes and questions the intermediacy of gold acetylides. By the means of NMR and mass spectrometry analysis, theoretical treatment and solution experiments, it was possible to rule out the involvement of these species in the catalytic cycle. This thesis has led to a number of publications in high-impact journals.

Bhajan Lal, Cornelius Borecho Bavoh, Jai Krishna Sahith Sayani
R4,364 Discovery Miles 43 640 Ships in 12 - 17 working days

This book is useful to flow assurance engineers, students, and industries who wish to be flow assurance authorities in the twenty-first-century oil and gas industry. The use of digital or artificial intelligence methods in flow assurance has increased recently to achieve fast results without any thorough training effectively. Generally, flow assurance covers all risks associated with maintaining the flow of oil and gas during any stage in the petroleum industry. Flow assurance in the oil and gas industry covers the anticipation, limitation, and/or prevention of hydrates, wax, asphaltenes, scale, and corrosion during operation. Flow assurance challenges mostly lead to stoppage of production or plugs, damage to pipelines or production facilities, economic losses, and in severe cases blowouts and loss of human lives. A combination of several chemical and non-chemical techniques is mostly used to prevent flow assurance issues in the industry. However, the use of models to anticipate, limit, and/or prevent flow assurance problems is recommended as the best and most suitable practice. The existing proposed flow assurance models on hydrates, wax, asphaltenes, scale, and corrosion management are challenged with accuracy and precision. They are not also limited by several parametric assumptions. Recently, machine learning methods have gained much attention as best practices for predicting flow assurance issues. Examples of these machine learning models include conventional approaches such as artificial neural network, support vector machine (SVM), least square support vector machine (LSSVM), random forest (RF), and hybrid models. The use of machine learning in flow assurance is growing, and thus, relevant knowledge and guidelines on their application methods and effectiveness are needed for academic, industrial, and research purposes. In this book, the authors focus on the use and abilities of various machine learning methods in flow assurance. Initially, basic definitions and use of machine learning in flow assurance are discussed in a broader scope within the oil and gas industry. The rest of the chapters discuss the use of machine learning in various flow assurance areas such as hydrates, wax, asphaltenes, scale, and corrosion. Also, the use of machine learning in practical field applications is discussed to understand the practical use of machine learning in flow assurance.

Hugo Campelo
R2,887 Discovery Miles 28 870 Ships in 10 - 15 working days

This thesis addresses a novel application of network modelling methodologies to power transformers. It develops a novel thermal model and compares its performance against that of a commercial computational fluid dynamics (CFD) code, as well as in experiments conducted in a dedicated setup built exclusively for this purpose. Hence, the thesis cross-links three of the most important aspects in high-quality research: model development, simulation and experimental validation. Network modelling is used to develop a tool to simulate the thermal performance of power transformers, widely acknowledged to be critical assets in electrical networks. After the strong de-regulation of electricity markets and de-carbonization of worldwide economies, electrical networks have been changing fast. Both asset owners and equipment manufacturers are being driven to develop increasingly accurate modelling capabilities in order to optimize either their operation or their design. Temperature is a critical parameter in every electric machine and power transformers are no exception. As such, the thesis is relevant for a wide range of stakeholders, from utilities to power transformer manufacturers, as well as researchers interested in the energy industry. It is written in straightforward language and employs a highly pedagogic approach, making it also suitable for non-experts.

Also, the authors strive to present the materials with an emphasis on the related physical phenomena and interpretation, to the extent possible. Through this book, engineering students can grasp the fundamental ideas of thermal cloaking and the associated mathematics, thus being better able to initiate their own research and explore new ideas in thermal cloaking. While not intended to be a general reference in the vast field of thermal cloaking research, this book is a unique monograph addressing the theoretical and analytical aspects of thermal cloaking within the scope mentioned above. This book also contains many independent analytical solutions to thermal cloaking problems that are not available in open literature. It is suitable for a three-credit graduate or advanced undergraduate course in engineering science.
