Download or read book Alternatives for the Demilitarization of Conventional Munitions written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-01-11 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military has a stockpile of approximately 400,000 tons of excess, obsolete, or unserviceable munitions. About 60,000 tons are added to the stockpile each year. Munitions include projectiles, bombs, rockets, landmines, and missiles. Open burning/open detonation (OB/OD) of these munitions has been a common disposal practice for decades, although it has decreased significantly since 2011. OB/OD is relatively quick, procedurally straightforward, and inexpensive. However, the downside of OB and OD is that they release contaminants from the operation directly into the environment. Over time, a number of technology alternatives to OB/OD have become available and more are in research and development. Alternative technologies generally involve some type of contained destruction of the energetic materials, including contained burning or contained detonation as well as contained methods that forego combustion or detonation. Alternatives for the Demilitarization of Conventional Munitions reviews the current conventional munitions demilitarization stockpile and analyzes existing and emerging disposal, treatment, and reuse technologies. This report identifies and evaluates any barriers to full-scale deployment of alternatives to OB/OD or non-closed loop incineration/combustion, and provides recommendations to overcome such barriers.

Download or read book Handbook of Spent Hydroprocessing Catalysts written by Meena Marafi and published by Elsevier. This book was released on 2017-01-18 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Spent Hydroprocessing Catalysts, Second Edition, covers all aspects of spent hydroprocessing catalysts, both regenerable and non-regenerable. It contains detailed information on hazardous characteristics of spent and regenerated catalysts. The information forms a basis for determining processing options to make decisions on whether spent catalysts can be either reused on refinery site after regeneration or used as the source of new materials. For non-regenerable spent catalysts, attention is paid to safety and ecological implications of utilizing landfill and other waste handling and storage options to ensure environmental acceptance. As such, this handbook can be used as a benchmark document to develop threshold limits of regulated species. - Includes experimental results and testing protocols which serve as a basis for the development of methodologies for the characterization of solid wastes - Presents a database which assists researchers in selecting/designing research projects on spent catalysts, i.e., regeneration vs. rejuvenation and metal reclamation - Provides the environmental laws, acts, and liabilities to raise awareness in safety and health issues in all aspects of spent catalysts - Contains solid waste management procedures specific to hydroprocessing that serve as a model for designing research projects in other solid waste areas
