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 evaluation (PMACWA) requested the nationwide learn Council (NRC) Committee on evaluation and review of different applied sciences for Demilitarization of Assembled Chemical guns: part II (the ACW II committee) to behavior an self sustaining medical and technical evaluate 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 method; the transpiring-wall supercritical water oxidation and gasphase chemical relief tactics of Foster Wheeler/Eco Logic/Kvaerner (FW/EL/K); and Teledyne-Commodore's solvated electron procedure. every one of those applied sciences represents a substitute for incineration for the total destruction of chemical brokers and linked full of life fabrics. The demonstration exams have been licensed by way of the PMACWA after an preliminary evaluation of every expertise. the result of that preliminary overview have been reviewed via an previous NRC committee, the Committee on evaluation and overview of other applied sciences for Demilitarization of Assembled Chemical guns (the ACW I committee).

For the current overview, the committee carried out an indepth exam of every know-how provider's facts, analyses, and demonstration attempt effects for the serious parts demonstrated. This assessment document supplementations the ACW I record and considers the demonstration functionality of the Demo II candidate applied sciences and their readiness for development to pilot-scale implementation. simply because checking out in those components is ongoing, the committee determined to chop brief its fact-finding efforts for enter to this file as of March 30, 2001.

The biogas handbook: Science, production and applications

With expanding pressures to make use of wastes successfully and sustainably, biogas creation represents essentially the most vital routes in the direction of achieving renewable strength pursuits. This accomplished reference at the improvement and deployment of biogas provide chains and know-how stories the position of biogas within the strength combine and descriptions the variety of biomass and waste assets for biogas construction.

Medical Waste Incineration and Pollution Prevention

The yearly price of treatment within the U niled States is swiftly coming near near one trillion money. surely, a lot of the increase in expenses is because of our healthiness industry's focus on excessive expertise remediation and danger avoidance measures. From contemporary public discussions it truly is changing into in­ creasingly obvious that to include the prices and even as expand some great benefits of overall healthiness care with out nationwide financial ruin will necessitate a lot larger consciousness to preventative drugs.

Example text

To reduce the unpleasant odor, the hydrolysate may have been treated with sodium hypochlorite and the thiol oxidized, but no information on this is given. ) According to the technology provider, the sludge produced in the biotreatment of nerve agents passed the TCLP tests satisfactorily. Because the treatment of these organophosphorus compounds was unsatisfactory, this sludge is not representative of the sludge that would be produced if the technology provider had developed an effective process.

Operation of the size reduction and slurrying system, and long-term operation of the supercritical water oxidation (SCWO) reactor with slurry, should be conducted before proceeding with a full-scale system. Recommendation GA-2. Before construction of a full-scale supercritical water oxidation (SCWO) system, additional evaluations of construction materials and fabrication techniques will be necessary because corrosion and plugging prevent continuous operation with the present design. If the new construction materials do not solve these problems, then alternative SCWO reactor designs should be investigated.

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. Energetics hydrolysate and agent hydrolysates were fed to the reactor in the following combinations: • VX hydrolysate, Comp B hydrolysate, and M28 propellant (the products of a processed M55 rocket) • GB hydrolysate and Comp B hydrolysate (the products of a processed M426 8-inch artillery shell) The major criterion for judging the nerve agent process was the same as for the mustard process—destruction of the Schedule 2 compounds and energetic products in the hydrolysate feed.
