Wormlike micelles are elongated flexible self-assembled structures created from the aggregation of amphiphiles and their resulting dynamic networks have gained attention for a number of uses, particularly in the oil industry. Written by experts, Wormlike Micelles describes the latest developments in the field providing an authoritative guide on the subject. The book starts with an introductory chapter giving an overview of the area and then looks at the three key topics of new wormlike micelle systems, characterization and applications. New systems covered in the first part include reverse wormlike micelles and stimuli-responsive wormlike micelles. The second part explores cutting-edge techniques that have led to advances in the understanding of their structure and dynamics, including direct imaging techniques and the combination of rheology with small-angle neutron scattering techniques. Finally, the book reviews their use in oil and gas well treatments as well as surfactant drag reducing solutions. Aimed at postgraduate students and researchers, this text is essential reading for anyone interested in soft matter systems.

Turbulent drag reduction by additives has long been a hot research topic. This phenomenon is inherently associated with multifold expertise. Solutions of drag-reducing additives are usually viscoelastic fluids having complicated rheological properties. Exploring the characteristics of drag-reduced turbulent flows calls for uniquely designed experimental and numerical simulation techniques and elaborate theoretical considerations. Pertinently understanding the turbulent drag reduction mechanism necessities mastering the fundamentals of turbulence and establishing a proper relationship between turbulence and the rheological properties induced by additives. Promoting the applications of the drag reduction phenomenon requires the knowledge from different fields such as chemical engineering, mechanical engineering, municipal engineering, and so on. This book gives a thorough elucidation of the turbulence characteristics and rheological behaviors, theories, special techniques and application issues for drag-reducing flows by surfactant additives based on the state-of-the-art of scientific research results through the latest experimental studies, numerical simulations and theoretical analyses. * Covers turbulent drag reduction, heat transfer reduction, complex rheology and the real-world applications of drag reduction * Introduces advanced testing techniques, such as PIV, LDA, and their applications in current experiments, illustrated with multiple diagrams and equations * Real-world examples of the topic s increasingly important industrial applications enable readers to implement cost- and energy-saving measures * Explains the tools before presenting the research results, to give readers coverage of the subject from both theoretical and experimental viewpoints * Consolidates interdisciplinary information on turbulent drag reduction by additives Turbulent Drag Reduction by Surfactant Additives is geared for researchers, graduate students, and engineers in the fields of Fluid Mechanics, Mechanical Engineering, Turbulence, Chemical Engineering, Municipal Engineering. Researchers and practitioners involved in the fields of Flow Control, Chemistry, Computational Fluid Dynamics, Experimental Fluid Dynamics, and Rheology will also find this book to be a much-needed reference on the topic.

This 2000 book provides an introduction to the nature, occurrence, physical properties, propagation and uses of surfactants in the petroleum industry. It is aimed principally at scientists and engineers who may encounter or use surfactants, whether in process design, petroleum production, or research and development. The primary focus is on applications of the principles of colloid and interface science to surfactant applications in the petroleum industry, and includes attention to practical processes and problems. Applications of surfactants in the petroleum industry are of great practical importance and are also quite diverse, since surfactants may be applied to advantage throughout the petroleum production process: in reservoirs, in oil and gas wells, in surface processing operations, and in environmental, health and safety applications. In each case appropriate knowledge and practices determine the economic and technical successes of the industrial process concerned. The book includes a comprehensive glossary, indexed and fully cross-referenced.

Volume 3, like the preceding volumes, focuses on the diversity of surfactants, both in terms of chemical structure and physico-chemical / surface active properties. These properties may be predictable for simple molecules but, for most commercial surfactants (which may be regarded as multi-component blends), this is not so easy. Yet it is important to develop a greater understanding of the interactions within a multi-component mixture, in order to select the most appropriate product for a particular application in which a combination of surface active properties is required.

A special feature of this volume is the initial chapter, in which the end uses of surface active agents are classified by industrial sector and the surfactant properties required for each application are presented in detail. The result is a unique guide to the influence of chemical structure on performance in end use, highlighting the benefits of particular surfactants and illustrating how some of the newer classes of surfactant may overcome the deficiencies of previously used products.

Offers coverage of the environmental behaviour of detergent additives, focusing on physiochemical interactions with soil and sediments. This text presents the current state of knowledge on recently introduced detergent additives, including zeolites, polycarboxylate compounds, ethylene dinitrilotetraacetic acid (EDTA), and nitrilotriacetic acid (NTA).

This book presents more than 800 advanced cleaning product formulations for household, industrial, and automotive applications. All formulations are completely different from those in other volumes.

Synthetic detergents rapidly replaced soap for most domestic cleaning purposes after World War II. Concurrently, great billows of foam began passing undegraded through sewage treatment plants into receiving waters, which were often sources for domestic water supplies. The detergent industry quickly learned that many surface-active agents--the active ingredients of synthetic detergents and the producers of foam--were not readily biodegradable. The most popular surface-active agent was alkyl benzene sulfonate (ABS). Industrialized societies had developed satisfactory sewage processes to treat domestic wastes, but even the most advanced treatment facilities proved incapable of degrading ABS. Biodegradable examines the development of synthetic detergents and the unanticipated pollution of surface waters and groundwaters by this new technology, as well as the social, political, and industrial responses that resulted in correction of the problem. Public and governmental pressure in the United States, the United Kingdom, and the Federal Republic of Germany led to the international detergent industry's finding a biodegradable substitute for ABS, namely, linear alkyl sulfonate (LAS). Its use from the mid-1960s solved the foaming pollution problem. The three countries responded to the problem very differently. West Germany almost immediately legislated that only those detergents that were more than eighty percent biodegradable could be sold. The U.S. government allowed the detergent industry to seek a solution while the Department of Health, Education, and Welfare monitored the industry's progress. In the U.K. the government created committees and required industry to cooperate with them to find a solution. Biodegradable not only examines problems resulting from a new technology but also compares and contrasts different societies' methods of dealing with these problems.
