The application of time-resolved luminescence spectroscopy to a remote uranyl sensor

Description: Time resolved luminescence spectroscopy is an effective method for the determination of a wide range of uranyl concentrations in aqueous samples. We have applied this technique to the development of a remote sensing device using fiber optic cables coupled with a micro flow cell in order to probe for uranyl in aqueous samples. This sensor incorporates a Nafion membrane through which UO{sub 2}{sup 2+} can diffuse in to a reaction/analysis chamber which holds phosphoric acid, a reagent which enhan… more

Cost comparison of solar detoxification with conventional alternatives for the destruction of trichloroethylene

Description: The purpose of this analysis is to compare the cost of solar waste detoxification processes with conventional alternatives for the treatment of trichloroethylene (TCE) in air. The solar processes that were evaluated are high flux photothermal oxidation (PHOTOX), high flux thermal catalytic reforming (SOLTOX), and low flux photocatalytic oxidation (PHOCAT). The high flux processes, PHOTOX and SOLTOX, were based on dish concentrator technology. The low flux photocatalytic process was based on par… more

Oxidation of hazardous waste in supercritical water: A comparison of modeling and experimental results for methanol destruction

Description: Recent experiments at Sandia National Laboratories conducted in conjunction with MODEC Corporation have demonstrated successful clean- up of contaminated water in a supercritical water reactor. These experiments targeted wastes of interest to Department of Energy production facilities. In this paper we present modeling and experimental results for a surrogate waste containing 98% water, 2% methanol, and parts per million of chlorinated hydrocarbons and laser dyes. Our initial modeling results c… more

Solar reforming of methane in a direct absorption catalytic reactor on a parabolic dish: 2, Modeling and analysis

Description: The CAtalytically Enhanced Solar Absorption Receiver (CAESAR) experiment was conducted to determine the thermal, chemical, and mechanical performance of a commercial-scale, dish-mounted, direct catalytic absorption receiver (DCAR) reactor over a range of steady state and transient (cloud) operating conditions. The focus of the experiment is on global performance such as receiver efficiencies and overall methane conversion; it was not intended to provide data for code validation. A numerical mod… more

Pressurized fluidized-bed hydroretorting of raw and beneficiated Eastern oil shales

Description: The Institute of Gas Technology (IGT) with US Department of Energy (DOE) support has developed a pressurized fluidized-bed hydroretorting (PFH) process for Eastern oil shales. Bench-scale tests have been conducted with raw and beneficiated shales in an advanced multipurpose research reactor (AMRR). Raw Alabama shale and raw and beneficiated Indiana shales were retorted at 515{degrees}C using hydrogen pressures of 4 and 7 MPa. Shale feed rates to the AMRR were 15 to 34 kg/h. High oils yields and… more
