By National Research Council, Division on Engineering and Physical Sciences, Board on Army Science and Technology, Committee on Review and Evaluation of Alternative Technologies for Demilitarization of Assembled Chemical Weapons: Phase II

By course of Congress, the U.S. division of Defense's (DoD's) application supervisor for the Assembled Chemical guns overview (PMACWA) requested the nationwide learn Council (NRC) Committee on assessment and overview of other applied sciences for Demilitarization of Assembled Chemical guns: part II (the ACW II committee) to behavior an self reliant clinical and technical evaluation of 3 replacement applied sciences (referred to as Demo II) into consideration for the destruction of assembled chemical guns at U.S. chemical guns garage websites. the 3 applied sciences are AEA applied sciences Corporation's (AEA's) electrochemical oxidation approach; the transpiring-wall supercritical water oxidation and gasphase chemical relief approaches of Foster Wheeler/Eco Logic/Kvaerner (FW/EL/K); and Teledyne-Commodore's solvated electron technique. every one of those applied sciences represents an alternative choice to incineration for the total destruction of chemical brokers and linked lively fabrics. The demonstration exams have been licensed by way of the PMACWA after an preliminary evaluate of every know-how. the result of that preliminary evaluation have been reviewed by way of an prior NRC committee, the Committee on evaluate and evaluate of other applied sciences for Demilitarization of Assembled Chemical guns (the ACW I committee).

For the current evaluate, the committee performed an indepth exam of every know-how provider's information, analyses, and demonstration try out effects for the serious parts demonstrated. This evaluate record vitamins the ACW I document and considers the demonstration functionality of the Demo II candidate applied sciences and their readiness for development to pilot-scale implementation. simply because trying out in those parts is ongoing, the committee made up our minds to chop brief its fact-finding efforts for enter to this record as of March 30, 2001.

Recyclingtechnik: Fachbuch für Lehre und Praxis (German Edition)

Das Recycling von Altgeräten, Werkstoffen und anderen Materialien leistet einen wesentlichen Beitrag zur Ressourcenschonung, Schadstoffbeseitigung und Energieeinsparung sowie zur Reduzierung von Deponievolumen. Die einsetzbare Recyclingtechnik ist dabei eine grundlegende Voraussetzung für die wirtschaftliche Realisierung der Prozesse.

Solid Waste Management in the World's Cities: Water and Sanitation in the World's Cities 2010

In our speedily urbanizing international society, strong waste administration might be a key problem dealing with all of the world's towns. reliable Waste administration within the World's towns presents a clean point of view and new facts on one of many largest concerns in city improvement. utilizing the framework of built-in Sustainable Waste administration (ISWM), the file brings jointly extraordinary study from 22 towns throughout six continents.

Analysis and Fate of Surfactants in the Aquatic Environment, Volume 40 (Comprehensive Analytical Chemistry)

An knowing of the destiny and behavior of natural chemical compounds, similar to surfactants, within the setting is a prerequisite for the sustainable improvement of human healthiness and ecosystems. As surfactants are being produced in large quantities, it is very important have an in depth wisdom approximately their lifetime within the atmosphere, their biodegradability in wastewater therapy vegetation and in average waters, and their ecotoxicity.

Because the UV/hydrogen peroxide process was tested under very adverse conditions, its ultimate operation could not be evaluated. No brines were evaporated. 7. quantification and characterization of the salts from the evaporation operations to ascertain what organic compounds are present 24 ALTERNATIVE TECHNOLOGIES FOR DEMILITARIZATION OF ASSEMBLED CHEMICAL WEAPONS Many partially oxygenated compounds were identified in the brine—some appeared in the dried salts and some evaporated in the drying operation.

Other differences are listed below: • A large amount of dextrose was added (about 44 lbs per pound of nerve agent products). , urea) represent about 95 percent of the total COD of the system. • The feed rate of agent/energetics hydrolysate to the biotreatment system was scaled back to accommodate the added dextrose. 0 percent for the HD/energetics hydrolysate feed. • The bio-oxidation process was augmented by a ultraviolet (UV)/hydrogen peroxide reactor. The operating conditions were based on tests performed at the technology provider’s laboratory that had demonstrated a DRE of more than 95 percent for Schedule 2 compounds.

9999 percent. 9999 percent. General Finding 3. The conditions under which aromatic nitro compounds, such as trinitrotoluene (TNT) or picric acid, will emulsify in the aqueous phase and not be completely hydrolyzed are not well understood. Therefore, this type of material could be present in the output stream from an energetic hydrolysis step. General Finding 4. The products of hydrolysis of some energetic materials have not been characterized well enough to support simultaneous hydrolysis of different kinds of energetic materials in the same batch reactor.
