This book was released on 2005 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 3 million gallons of oil or refined petroleum products are spilled into U.S. waters every year. Oil dispersants (chemical agents such as surfactants, solvents, and other compounds) are used to reduce the effect of oil spills by changing the chemical and physical properties of the oil. By enhancing the amount of oil that physically mixes into the water, dispersants can reduce the potential that a surface slick will contaminate shoreline habitats. Although called for in the Oil Pollution Act of 1990 as a tool for minimizing the impact of oil spills, the use of chemical dispersants has long been controversial. This book reviews the adequacy of existing information and ongoing research regarding the effectiveness of dispersants as an oil spill response technique, as well as the effect of dispersed oil on marine and coastal ecosystems. Oil Spill Dispersants also includes recommended steps for policy makers faced with making hard choices regarding the use of dispersants as part of spill contingency planning efforts or during actual spills.

Available in PDF, EPUB and Kindle. Book excerpt: teacher Professor Ernst-Joachim Ivers to whom I still owe many insights 20 years after the end of his working life. This English edition is not an unedited translation of the German edition of 1990. The text has been substantially revised in some chapters, taking into account the literature published in the mean time. I wish to thank Dr.-Ing. H. Finken, Freiberg, who has prepared the translation from German into English with deep scientific understanding and in close contact with the author. I also wish to express my gratitude to Chapman & Hall for their support to this project without which the English edition could not have been published. Dr.-Ing. habil. C. Bernhardt Freiberg 1 Position, tasks and structure of particle size analysis Today the concept of particle size analysis is that of a special field of particle measurement technology, which in turn is part of particulate technology. This classification has developed over the last 20 years; it is the result of a scientific integration process taking place in many industrialized countries of the world. In recent years, the meaning and mutual connection of the related concepts as well as the tasks of the scientific disciplines designated by them have been the subject of intensive discussion which, however, has not led to a generally accepted terminology.

Book excerpt: The aim of the fineness analysis is to determine the particle-size distribution. Methods by which only a numerical value is found for a quality of the product depending on the fineness are of slight value except in cases where the particlesize distribution is already known with the exception of a constant.

This book was released on 2020-04-24 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether the result of an oil well blowout, vessel collision or grounding, leaking pipeline, or other incident at sea, each marine oil spill will present unique circumstances and challenges. The oil type and properties, location, time of year, duration of spill, water depth, environmental conditions, affected biomes, potential human community impact, and available resources may vary significantly. Also, each spill may be governed by policy guidelines, such as those set forth in the National Response Plan, Regional Response Plans, or Area Contingency Plans. To respond effectively to the specific conditions presented during an oil spill, spill responders have used a variety of response optionsâ€"including mechanical recovery of oil using skimmers and booms, in situ burning of oil, monitored natural attenuation of oil, and dispersion of oil by chemical dispersants. Because each response method has advantages and disadvantages, it is important to understand specific scenarios where a net benefit may be achieved by using a particular tool or combination of tools. This report builds on two previous National Research Council reports on dispersant use to provide a current understanding of the state of science and to inform future marine oil spill response operations. The response to the 2010 Deepwater Horizon spill included an unprecedented use of dispersants via both surface application and subsea injection. The magnitude of the spill stimulated interest and funding for research on oil spill response, and dispersant use in particular. This study assesses the effects and efficacy of dispersants as an oil spill response tool and evaluates trade-offs associated with dispersant use.

This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective was to develop methods to determine the factors that control how low-level mixtures of PANs degrade aerobically in marine sediment systems, in order to determine what rate and extent of biodegradation can be expected in marine sediments under natural and engineered conditions. Specifically, this expansion was added to provide the capability to examine the effects of sediment grain size on laboratory and field observations of PAN behavior. Studies were carried out to characterize the performance of a prototype, bench-top Laser in Situ Scattering Transmissometer (LISST) under a variety of conditions to determine its utility and limitations in the laboratory and field. The impact of grain size effects on experimental and field interpretation was examined. Since grain size is one of the controlling parameters for contaminant distribution, an understanding of the behavior and fate of particles in the field and laboratory as a function of grain size reveals much about the behavior and fate of contaminants in the same environments. These studies have allowed us to optimize these tools to address those goals, and to put the strengths and limitations of the methods in perspective.
Download or read book Oil in the Sea III written by National Research Council and published by National Academies Press. This book was released on 2003-03-14 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
