Title: Development of Carbon-14 Waste Destruction and Recovery System Using AC Plasma Torch Technology Final Report CRADA No. TC02108.0

Abstract

This was a collaborative effort between Lawrence Livermore National Security, LLC as manager and operator of Lawrence Livermore National Laboratory (LLNL) and ISOFLEX USA (ISOFLEX), to 1) develop and test a prototype waste destruction system ("System") using AC plasma torch technology to break down and drastically reduce the volume of Carbon-14 (C-14) contaminated medical laboratory wastes while satisfying all environmental regulations, and 2) develop and demonstrate methods for recovering 99%+ of the carbon including the C-14 allowing for possible re-use as a tagging and labeling tool in the biomedical industry.

  • Over-dependence on fossil fuel has spurred research on alternative energy. Inedible plant materials such as grass and corn stover represent abundant renewable natural resources that can be transformed into biofuel. Problems in enzymatic conversion of biomass to sugars include the use of incomplete synergistic enzymes, end-product inhibition, and adsorption and loss of enzymes necessitating their use in large quantities. Technova Corporation will develop a defined consortium of natural microorganisms that will efficiently break down biomass to energy-rich soluble sugars, and convert them to cleaner-burning ethanol fuel. The project will also develop a novel biocatalytic hybrid reactor system dedicated to thismore » bioprocess, which embodies recent advances in nanotechnology. NREL will participate to develop a continuous fermentation process.« less
  • The goal of this project was to develop a prototype medical waste destruction facility based on the AC plasma torch capable of processing 150 kg of waste per hour while satisfying US EPA emission standards. The project was to provide the first opportunity for a joint U.S.-Russian project using an AC Plasma Torch in a hazardous waste destruction system to be assembled and operated in the U.S. thus promoting the commercialization in the U.S. of this joint U.S.-Russian developed technology. This project was a collaboration between the Russian Institute Soliton- NTT, the U.S industrial partner Scientific Utilization Inc. (SUI) andmore » Lawrence Livermore National Laboratory ( LLNL). The project was funded by DOE for a total of $1.2 million with $600K for allocated for Phase I and $600K for Phase II. The Russian team received about $800K over the two (2) year period while LLNL received $400K. SUI was to provide in kind matching funds totaling $1.2 million.« less
  • Combustion and Environmental Research Facility (CERF) formerly known as The Fuel Evaluation Facility was used from March 29 to April 17, 1993 for the sole purpose of evaluating the Rocket Research (RR) plasma torch and testing its effectiveness in reducing NO{sub x} emissions from coal flames. Two spare facility convective sections were modified to accept the torch and to allow for effective mixing in the convective section chambers. The torch was placed into the fourth convective section and a 1-inch fused silica bluff body was placed immediately upstream of the torch to further enhance the mixing at the torch injectionmore » location. The gases anticipated for use during testing included ammonia (NH{sub 3}) , hydrogen (H{sub 2}) , carbon monoxide (CO), and methane (CH{sub 4}). Ammonia and hydrogen were planned as the gases which would be introduced through the torch directly while CO and CH{sub 4} would be used only in the torch secondary injection ring. The intent was to minimize any potential fouling problems with the carbon containing gases. Actual test conditions did not allow evaluation of the CO or the CH{sub 4} due to continued intermittent operation of the Rocket Research plasma torch. The torch had not been previously tested under conditions similar to the high temperature condition of the CERF and consequently it was found that the torch would not operate effectively under the test conditions. The torch using NH{sub 3} and H{sub 2} as primary and secondary gases has evaluated for short periods of time.« less
