Available in PDF, EPUB and Kindle. Book excerpt: Surfactants are molecules that contain groups that are water-loving (hydrophilic) and oil-loving (lipophilic). The central question in formulations is often which of the two portions dominate the behavior of the surfactant. For many years that question was answered in terms of the surfactant structure only. However, the modern view is that the hydrophilic-lipophilic nature of the surfactant is the result of surfactant structure and formulation conditions (nature of the oil, temperature, aqueous phase composition) as captured by a semi-empirical equation called the hydrophilic-lipophilic difference (HLD). The HLD is a dimensionless number that indicate the approach to the point where the surfactant inverts its solubility from being water-soluble (negative HLD) to oil-soluble (positive HLD). The HLD alone is a good indicator of how the formulation could behave but it does not produce any formulation property that can be used to predict product performance. The net-average curvature (NAC) are a set of equations that take the value of HLD to predict the properties of the formulation, such as oil (and/or water) solubilization capacity, interfacial tension, phase diagrams, contact angle and others.Surfactant Formulation Engineering using HLD and NAC will not only introduce the reader to HLD-NAC but also to the practical use of these concepts in numerous applications ranging from application in the petroleum industry, to environmental remediation, to food, cosmetic and pharmaceutical applications, and even nanotechnology. The last part of the book will look at the molecular origins of the empirical terms in HLD via the Integrated Free Energy Model (IFEM). - Concentrates on the HLD and NAC, providing industrially-relevant examples - Provides the only single depository for HLD parameters - Balances theory and application, with insights from both academic and industrial authors - Includes examples relevant to a wide range of fields, with practical guides on how to go from the formulation objective(s) to an actual formulation design

Download or read book Modern Chemical Enhanced Oil Recovery written by James J.Sheng and published by Gulf Professional Publishing. This book was released on 2010-11-25 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. But only about 10 percent of a reservoir's original oil in place is typically produced during primary recovery. Secondary recovery techniques to the field's productive life generally by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place. In the past two decades, major oil companies and research organizations have conducted extensive theoretical and laboratory EOR (enhanced oil recovery) researches, to include validating pilot and field trials relevant to much needed domestic commercial application, while western countries had terminated such endeavours almost completely due to low oil prices. In recent years, oil demand has soared and now these operations have become more desirable. This book is about the recent developments in the area as well as the technology for enhancing oil recovery. The book provides important case studies related to over one hundred EOR pilot and field applications in a variety of oil fields. These case studies focus on practical problems, underlying theoretical and modelling methods, operational parameters (e.g., injected chemical concentration, slug sizes, flooding schemes and well spacing), solutions and sensitivity studies, and performance optimization strategies. The book strikes an ideal balance between theory and practice, and would be invaluable to academicians and oil company practitioners alike. - Updated chemical EOR fundamentals providing clear picture of fundamental concepts - Practical cases with problems and solutions providing practical analogues and experiences - Actual data regarding ranges of operation parameters providing initial design parameters - Step-by-step calculation examples providing practical engineers with convenient procedures

Download or read book Catastrophic Perioperative Complications and Management written by Charles J. Fox, III and published by Springer. This book was released on 2019-03-19 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: For years the administrative of anesthesia was extremely dangerous and risky. Because of this the surgeon and anesthesiologist had to balance the risks and benefits for each patient before proceeding with surgery. In the last two decades the care of the surgical patient has changed dramatically. New equipment, monitors and pharmacologic agents have transformed surgical technique and improved outcomes. Patients once deemed “too sick” for the operating room are found frequently on operating room schedules nationwide. Today, anesthesiology for the healthy patient in most developed countries is extremely safe. However, perioperative complications still occur. These events can be catastrophic for patients and may have serious implications for residents, surgical and anesthesiology staff and nurses. Prompt recognition and management of these incidents may reduce or negate complications. This is based on a fundamental base of knowledge acquired through several avenues and practiced with other team members to maximize outcomes. Engagement of all caregivers impacts outcomes. Many organizations do not have the structural components or education to recognize or manage these catastrophic events. This textbook will provide educational material for the many students, as well as nurses, residents or attending physicians who participate in perioperative medicine. It will focus on the most serious perioperative complications and include a discussion of the pathophysiologic and pharmacologic implications unique to each. Additionally, it will provide medicolegal information pertinent to those providing care to these patients. All chapters will be written with the most current and relevant information by leading experts in each field.The layout and format is designed to be purposeful, logical and visually effective. Other features include review questions and answers, chapter summaries and shaded call-out boxes to facilitate learning. Catastrophic Perioperative Complications and Management will be of great utility for medical and nursing students, anesthesiology residents, student nurse anesthestists, surgical residents, nurses involved in perioperative medicine as well as surgical and anesthesiology attending physicians.

Download or read book Chemical Enhanced Oil Recovery written by Patrizio Raffa and published by Walter de Gruyter GmbH & Co KG. This book was released on 2019-07-22 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies. About the Authors Patrizio Raffa is Assistant Professor at the University of Groningen. He focuses on design and synthesis of new polymeric materials optimized for industrial applications such as EOR, coatings and smart materials. He (co)authored about 40 articles in peer reviewed journals. Pablo Druetta works as lecturer at the University of Groningen (RUG) and as engineering consultant. He received his Ph.D. from RUG in 2018 and has been teaching at a graduate level for 15 years. His research focus lies on computational fluid dynamics (CFD).
