Available in PDF, EPUB and Kindle. Book excerpt: As a result of past operations, the U.S. Amy has numerous buildings and large quantities of process equipment that are contaminated with explosives. Recent changes in laws also require all detonation scrap to be free of explosive residue prior to recycle. Before these materials can be recycled or disposed of, the residual explosives must be removed. Removal of residual explosives is necessary to avoid creating safety and environmental hazards. If the process equipment is to be land filled, residual explosives may migrate into the soil and ultimately contaminate groundwater. Building structures that have been used for explosives manufacture are usually slated for demolition and disposal of the rubble. Demolition of a building that has residual explosives can be dangerous. Disposal of contaminated rubble may contribute to soil and groundwater contamination. Probably the two most common methods in present use for decontamination are steam cleaning and decontamination by fire (burn it to the ground). Steam cleaning is in most cases effective but provides only surface decontamination and is not effective on hard to access areas. It is difficult to completely decontaminate concrete with steam. Steam cleaning of complex items such as motors cannot assure that interior areas are cleaned. Burning of structures contaminated with explosives is no longer an environmentally acceptable method of decontamination. In 1982, USATHAMA began a project aimed at developing new, improved procedures for decontaminating structures and equipment contaminated with explosives. The goal of this on-going project is to develop a method which will be safe, produce little or no waste, and will assure a high degree of decontamination. The process would have to be effective at removing contaminants from metal, wood, painted concrete, and bare concrete. The first phase of this project is a review of existing techniques and the consideration of novel techniques.

Available in PDF, EPUB and Kindle. Book excerpt: One of the United States Army Toxic and Hazardous Materials Agency's mandates is to restore contaminated Army facilities which have been used for manufacturing, loading, packing and storing explosives so that these facilities can be removed or reclaimed for alternate use. Explosive contaminants of concern include TNT, 2,4-DNT, 2,6-DNT, HMX, RDX, Tetryl and other explosives manufactured and used by the Army. Facilities to be addressed include the building production equipment, above and underground storage tanks, wastewater/ sludge sumps ventilation ducts, conduits and related explosive/munition production. The decontamination involves the removal of explosives from exposed surfaces of the materials as well as explosives that have penetrated porous media, cracks, and expansion joints. Site inspections have been performed and the contaminated structures include a wide range of concrete and wood frame structures.
Download or read book Hot Gas Decontamination of Explosives Contaminated Equipment written by and published by . This book was released on 1992 with total page 8 pages. 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.
Download or read book Decontamination of Chemical Agent Contaminated Structures and Equipment written by and published by . This book was released on 1992 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operations involving chemical agents such as manufacture, loading, storage, and demilitarization have resulted in the contamination of buildings and a wide variety of processing equipment. The contamination has been caused by a number of chemical agents with the most persistent being mustard agents. Materials that are contaminated include concrete (in floors and walls), metals (in piping and process equipment), and wood. All of these materials exist in both painted and unpainted forms. Many of the contaminated facilities have potential reuses or monetary value as excess property if they can be properly decontaminated. Much of the contaminated process equipment also has monetary value as scrap material if properly decontaminated. Currently this value cannot be realized since the only acceptable decontamination method involves destruction and incineration of the contaminated material. Past efforts at resolving this situation have identified some 56 concepts that could be utilized, with 5 having been evaluated under laboratory conditions. These concepts include thermal, abrasive, chemical, and extractive removal schemes. Each of these technologies was evaluated based on destruction efficiency, mass transfer, safety, damage to existing materials, penetration depth, applicability to complex surfaces, cost, and waste management. Based on these comparisons, hot gas technology was identified as the most suitable methodology. Currently, a full-scale demonstration is in the design phase for implementation at Rocky Mountain Arsenal. The chosen site was originally contaminated with mustard and mustard degradation by-products from past demilitarization activities. The building contains concrete approximately 18 inches thick, large metal storage tanks, process piping, motors, and pumps.

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.

Hopper and published by . This book was released on 1985 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Study experimentally evaluated concepts, identified, evaluated, and recommended in a previous phase, for decontamination of explosive contaminated buildings. Five concepts were first submitted to laboratory scale screening studies. The successful operating conditions so identified were then further evaluated in bench scale studies using 5-inch x 5-inch coupons of typical building materials, both in a painted and unpainted condition. An engineering and economic analysis was then performed on the three concepts (Hot Gas, NaOH/ DMSO Reduction, and combined Hot Gas/Chemical) so demonstrated to be effective. Remaining knowledge gaps pertaining to the implementation of these concepts were then identified and methods for resolving them delineated in a Field Test Plan.
