This book was released on 1995 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: TVA demonstrated at Hawthorne Army Depot in June-October 1994 that the Hot Gas Decontamination (HGD) process was effective in removing and destroying residues of explosives from obsolete munitions as the final step of the demilitarization process. Prior testing demonstrated the applicability of the process to decontaminate residues of TNT and Ammonium Picrate from various items singly or in small lots. The present tests extended the process to additional munitions and explosives and tested them in quantities approaching the projected usage of the facility in routine operations. Specimens of actual contaminated munitions were examined in a baseline study to determine whether spiking levels were representative of actual conditions and whether sampling and analytical methods prescribed for spiked munitions were effective for actual contaminants and residues. The test program was comprised of 34 tests of five explosives (Ammonium Picrate, Comp A-3, Comp B, HBx, and TNT) and six munitions (3-inch, 5-inch, 106mm, and 175mm projectiles, MK 25 Ship Nines, and MK 54 Depth Bcmbs) with treatment times of 6 to 32 hours.

Book excerpt: The purpose of this assessment was to determine emissions from the hot gas decontaminations (HGD) system, as tested. The results will be used by the State of Nevada Bureau of Air Quality to set operational and emissions limits. The U.S. Army Environmental Center (USAEC) is investigating technologies to effectively treat explosives-contaminated components. Pilot studies have shown that decontamination of structural components is possible using a heated gas to thermally decompose or volatilize explosives with subsequent incineration in a thermal oxidizer (references 3 and 4). The pilot study conducted at HWAAP from 10 July to 21 September 1989 concluded that the HGD system is effective for treating items contaminated with TNT and ammonium picrate (reference 4). A second pilot study, from 20 June to 31 October 1994, was conducted to determine if the HGD system would successfully decontaminate items contaminated with explosives; CONP A-3, COMP B, HBX, H-6, RDX, TNT, and Yellow D (reference 5). Stack gas testing was conducted during 17-29 October to support HWAAP permitting requirements.

Available in PDF, EPUB and Kindle. Book excerpt: Explosives manufacturing, handling, and demilitarization operations at U.S. Army industrial facilities have resulted in contaminated process equipment, scrap metal, and sewer systems. Because of the residual contamination, these items can not be reused or disposed. The U.S. Army Toxic and Hazardous Materials Agency has studied technologies to effectively treat these explosive-contaminated materials. The most promising of these technologies was hot gas decontamination. A recent field demonstration at Hawthorne Army Ammunition Plant demonstrated the ability of the hot gas decontamination system to effectively remove explosives such that the test items are not characteristically hazardous and are appropriate for disposal as scrap. Based upon the success of this demonstration, the Hawthorne Army Ammunition Plant intends to implement this, technology in current demilitarization operations. Full-scale operation will begin following completion of several system changes. The results of the field demonstration and the proposed system changes are described.

This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The manufacture, handling, and loading of explosives at Army industrial facilities have resulted in the contamination of process equipment such as piping, pumps, motors, powder boxes, and sewer systems. Because of this residual contamination, process equipment, piping and sewer lines cannot be reused or disposed as scrap without some sort of remedial treatment. Over the years, the U.S. Army Environmental Center (USAEC) has investigated technologies that could be used effectively to treat explosives-contaminated materials. Using process equipment supplied by the government, pilot studies conducted at Hawthorne Army Ammunition Plant have shown that decontamination of explosives-contaminated structural components is possible. The process used a heated gas to thermally decompose or volatilize explosives with subsequent incineration in an afterburner. Based on engineering data gathered during the Hawthorne pilot studies, WESTON, under contract to the United States Army Environmental Center (USAEC), was requested to design and supply a hot-gas decontamination system which is transportable and easily procured through commercial sources. The finished equipment was delivered to the Alabama Army Ammunition Plant (ALAAP) to conduct an equipment shakedown and validation testing using explosives-contaminated piping and oversized debris. The purpose of validation testing was to verify the effectiveness of the hot-gas process to remediate explosives contaminated piping and debris to levels which would allow this material to be disposed of as scrap and to maintain at least a 99.99% destruction and removal efficiency (DRE) of contaminants out of the system afterburner. A total of nineteen (19) test runs were conducted during the validation testing period.

Download or read book Design Guidance Manual Low Cost Disposable Hot Gas Decontamination System for Explosives Contaminated Equipment and Facilities written by William Kelso and published by . This book was released on 1998 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of its long-term environmental program, the Department of Defense (DoD) is required to decontaminate and remove explosives contamination from equipment and buildings at numerous DoD installations. An environmentally-safe, non-destructive method to decontaminate facilities is by the Hot Gas Decontamination (HGD) technology developed by the U.S. Army Environmental Center (USAEC). The HGD technology uses controlled heat to volatilize and thermally decompose the explosives contamination. The process was proven technically effective for decontaminating explosives contaminated equipment and facilities during several field demonstrations conducted by the USAEC. This Design Guidance Manual will assist installation personnel in determining the applicability and effectiveness of the Hot Gas technology at their site. The manual provides sufficient design information to move directly to detailed design, procurement, construction and operation of a HGD system. Technical information necessary to develop a budgetary cost estimate for implementation of the HGD process at an installation is also presented.
Download or read book Pilot Plant Testing of Caustic Spray Hot Gas Building Decontamination Process written by and published by . This book was released on 1987 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Army operates and/or owns ammunition plants and depots involved in the manufacture, processing, loading and storage of pyrotechnic, explosives and propellant (PEP) materials. These operations involve permanent facilities and a variety of process and handling equipment. Many of these facilities are in an inactive or stand-by status and are candidates for excessing operations. In some cases, explosive contaminated structures have significant reuse potential for conversion to other industrial processes. In order to recover these valuable resources, non-destructive decontamination techniques are necessary to eliminate the explosive and toxic hazard of any munition processing wastes. The use of hot gas treatment (with or without caustic spray) appears to be a promising means of decontaminating explosive contaminated buildings. More importantly, this hot gas decontamination process appears to be non-destructive in nature and, therefore, has the potential for rendering treated buildings available for reuse or excessing operations.

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.
