Available in PDF, EPUB and Kindle. Book excerpt: The two research projects undertaken at UCLA under this grant have focused on the analysis and control of mixing and reaction processes during the destruction of hazardous waste surrogates as well as pyrolysis gas surrogates from a primary treatment system such as plasma arc pyrolysis. Both projects have relevance to the thermal treatment and destruction of shipboard wastes generated on Navy vessels, and both projects have demonstrated extremely high degrees of efficiency and toxic emissions reduction. The first project, the resonant incinerator/afterburner or 'trapped vortex' combustor, produced waste surrogate destruction efficiencies (DREs) which exceeded U.S. EPA standards by four orders of magnitude under appropriate conditions of external acoustical forcing. Detailed laser diagnostics and numerical simulation of the device enabled insight into the physical processes behind such excellent performance. The second project, the lobed injector/burner, is a concept which provides a means of rapid initial mixing of fuel/waste/off-gas and air in a thermal destruction device via passive flow control. Experiments as well as numerical modeling demonstrated a significant degree of mixing enhancement in lobed injector flowfields, in addition to the potential for ignition delay and the associated reduction in toxic emissions.

This book was released on 2000-10-21 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incineration has been used widely for waste disposal, including household, hazardous, and medical wasteâ€"but there is increasing public concern over the benefits of combusting the waste versus the health risk from pollutants emitted during combustion. Waste Incineration and Public Health informs the emerging debate with the most up-to-date information available on incineration, pollution, and human healthâ€"along with expert conclusions and recommendations for further research and improvement of such areas as risk communication. The committee provides details on: Processes involved in incineration and how contaminants are released. Environmental dynamics of contaminants and routes of human exposure. Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.

Download or read book Hazardous Air Emissions from Incineration written by Calvin R. Brunner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive handbook on the relationship of air pollution to incineration. Incineration is becoming the predominant method of dealing with many of our waste products and its most significant envi ronmental impact is on the air. This book includes information on emissions as well as on equipment design. Two chapters deal with the regulations governing incinerator emissions as well as the thermal destruction of hazardous wastes. Four chapters describe the nature of the emissions generated by the incin eration process. These particulate, gaseous, and odor emissions, are hazardous as well as deleterious to public well-being and aesthetics. Also included is a complete and timely discussion of dioxin generation and discharges. Three chapters describe the incineration equipment in general use today and methods of calculating gas flows and air discharges from these systems. Five chapters discuss the types of gas cleaning equipment available with sizing information and expected efficiencies. The nature of the gas cleaning process is discussed in detail. Criteria for selection of the opti mum system for a particular application is also included. The dispersion of an atmospheric discharge to the surrounding areas and/or communities is a vital concern in assessing the nature of that discharge and its impact, or potential hazards. A chapter is devoted to a relative simple method of estimating atmospheric dispersion.

Download or read book Small Scale Municipal Solid Waste Energy Recovery Systems written by Brickner Gershman and published by Springer. This book was released on 1986 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is designed to give local government elected officials and their staff the background information they need on the state of the art in small scale municipal waste-to-energy project development. It will, of course, be of interest to many others in the field. The small-scale segment of the municipal waste energy recovery industry has grown and changed in many ways in recent years. With increasingly stringent environmental regulations pushing up the costs of landfilling, as well as today's higher prices for oil and natural gas, the economics of small-scale systems are attractive to smaller communities or counties which might at one time only have considered joining a multijurisdictional large-scale project. The difficulties involved in devel oping a project that envelops numerous governmental entities are discouraging, and a small, local project may be more readily achievable. Gershman, Brickner & Bratton, Inc. hopes this book will be of assistance to those who are considering such a project, providing guidance and encouragement, as well as practical information on technologies, eco nomics, energy markets, financing, environmental issues, and the pitfalls of project development.

Available in PDF, EPUB and Kindle. Book excerpt: The growing problem of changing environmental conditions caused by climate destabilization is well recognized as one of the defining issues of our time. The root problem is greenhouse gas emissions, and the fundamental solution is curbing those emissions. Climate geoengineering has often been considered to be a "last-ditch" response to climate change, to be used only if climate change damage should produce extreme hardship. Although the likelihood of eventually needing to resort to these efforts grows with every year of inaction on emissions control, there is a lack of information on these ways of potentially intervening in the climate system. As one of a two-book report, this volume of Climate Intervention discusses albedo modification - changing the fraction of incoming solar radiation that reaches the surface. This approach would deliberately modify the energy budget of Earth to produce a cooling designed to compensate for some of the effects of warming associated with greenhouse gas increases. The prospect of large-scale albedo modification raises political and governance issues at national and global levels, as well as ethical concerns. Climate Intervention: Reflecting Sunlight to Cool Earth discusses some of the social, political, and legal issues surrounding these proposed techniques. It is far easier to modify Earth's albedo than to determine whether it should be done or what the consequences might be of such an action. One serious concern is that such an action could be unilaterally undertaken by a small nation or smaller entity for its own benefit without international sanction and regardless of international consequences. Transparency in discussing this subject is critical. In the spirit of that transparency, Climate Intervention: Reflecting Sunlight to Cool Earth was based on peer-reviewed literature and the judgments of the authoring committee; no new research was done as part of this study and all data and information used are from entirely open sources. By helping to bring light to this topic area, this book will help leaders to be far more knowledgeable about the consequences of albedo modification approaches before they face a decision whether or not to use them.
Download or read book Carbon Filtration for Reducing Emissions from Chemical Agent Incineration written by National Research Council and published by National Academies Press. This book was released on 1999-09-12 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the Army's evaluation of carbon filters for use in the baseline incineration PAS, as well as the Army's change management process (the Army's tool for evaluating major equipment and operational changes to disposal facilities). In preparing this report, members of the Stockpile Committee evaluated exhaust gas emissions testing at the two operating baseline incineration systems, JACADS and the TOCDF; evaluated the development of the dilute SOPC carbon filter simulation model; and evaluated the conceptual design of a modified PAS with an activated carbon filter. The two major risk assessments conducted for each continental disposal site that use the baseline system, namely, (1) the quantitative risk assessment, which evaluates the risks and consequences of accidental agent releases, and (2) the health risk assessment, which evaluates the potential effects of nonagent emissions on human health and the environment, were also examined.
Download or read book WHO global air quality guidelines written by Weltgesundheitsorganisation and published by World Health Organization. This book was released on 2021-09-07 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of these updated global guidelines is to offer health-based air quality guideline levels, expressed as long-term or short-term concentrations for six key air pollutants: PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. In addition, the guidelines provide interim targets to guide reduction efforts of these pollutants, as well as good practice statements for the management of certain types of PM (i.e., black carbon/elemental carbon, ultrafine particles, particles originating from sand and duststorms). These guidelines are not legally binding standards; however, they provide WHO Member States with an evidence-informed tool, which they can use to inform legislation and policy. Ultimately, the goal of these guidelines is to help reduce levels of air pollutants in order to decrease the enormous health burden resulting from the exposure to air pollution worldwide.

Download or read book Negative Emissions Technologies and Reliable Sequestration written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-04-08 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.
