Coal/Polymer Coprocessing With Efficient Use of Hydrogen

Description: The final project period was devoted to investigating the binary mixture pyrolysis of polypropylene and polystyrene. Their interactions were assessed in order to provide a baseline for experiments with multicomponent mixtures of polymers with coal. Pyrolysis of polypropylene, polystyrene and their binary mixture was investigated at temperatures of 350 C and 420 C with reaction times from 1 to 180 minutes. Two different loadings, 10 mg and 20 mg, were studied for neat polypropylene and polystyre… more

Development of object-oriented tools for the numerical solution of reactive flow

Description: The primary work carried out under the subcontract involved the development of object-oriented application software, within the Overture framework of codes, for the numerical simulation of high speed reactive flow. The mathematical model on which the software is based is the reactive Euler equations. The implementation of this model is fairly general and allows for multiple reacting species and reaction rates and a general equation of state with the aim of being able to simulate experimentally … more

Direct Push Groundwater Circulation Wells for Remediation of BTEX and Volatile Organics

Description: Direct push groundwater circulation wells (DP-GCW) are a promising technology for remediation of groundwater contaminated with dissolved hydrocarbons and chlorinated solvents. In these wells, groundwater is withdrawn from the formation at the bottom of the well, aerated and vapor stripped and injected back into the formation at or above the water table. Previous field studies have shown that: (a) GCWs can circulate significant volumes of groundwater; and (b) GCWs can effectively remove volatile… more

Electric Demand Reduction for the U.S. Navy Public Works Center San Diego, California

Description: Pacific Northwest National Laboratory investigated the profitability of operating a Navy ship's generators (in San Diego) during high electricity price periods rather than the ships hooking up to the Base electrical system for power. Profitability is predicated on the trade-off between the operating and maintenance cost incurred by the Navy for operating the ship generators and the net profit associated with the sale of the electric power on the spot market. In addition, PNNL assessed the use o… more

Enhanced Oil Recovery with Downhole Vibration Stimulation in Osage County Oklahoma

Description: This Technical Quarterly Report is for the reporting period July 1, 2000 to September 30, 2000. The report provides details of the work done on the project entitled ''Enhanced Oil Recovery with Downhole Vibration Stimulation in Osage County Oklahoma''. The project is divided into nine separate tasks. Since this is the first Quarterly report, much of the work done is of a preliminary nature. Several of the tasks are being worked on simultaneously, while other tasks are dependent on earlier tasks… more

Frequency Modulation Spectroscopy Modeling for Remote Chemical Detection

Description: Frequency modulation (FM) spectroscopy techniques show promise for active infrared remote chemical sensing. FM spectroscopy techniques have reduced sensitivity to optical and electronic noise, and are relatively immune to the effects of various electronic and mechanical drifts. FM systems are responsive to sharp spectral features and can therefore reduce the effects of spectral clutter due to interfering chemicals in the plume or in the atmosphere. The relatively high modulation frequencies use… more

Hydrologic Behavior of Two Engineered Barriers Following Extreme Wetting

Description: Many engineered barriers are expected to function for hundreds of years or longer. Over the course of time, it is likely that some barriers will experience infiltration to the point of breakthrough. This study compares the recovery from breakthrough of two storage- evapotranspiration type engineered barriers. Replicates of test plots comprising thick soil and capillary/biobarrier covers were wetted to breakthrough in 1997. Test plots were kept cleared of vegetation to maximize hydrologic stress… more

Identification and temporal behavior of radical intermediates formed during the combustion and pyrolysis of gaseous fuels: Kinetic pathways to soot formation. Final performance report, July 1, 1997 - September 30, 2000

Description: A shock tube coupled to a time-of-flight mass spectrometer has been employed to analyze the dynamic behavior of reactants, products, and intermediates in those reaction systems which are most pertinent to understanding the chemistry attendant to the soot formation process. The measurement of the decay rates of the reactants, the rate of formation of intermediates and products have been used to determine rate constants over a wide temperature range. Recent examples include the pyrolyses of allen… more

Low NOx Burner Development Program - Final Report - 09/15/1996 - 09/30/2000

Description: This report describes the work performed to develop and demonstrate the VISTA combustor. The development effort was planned for three phases. Laboratory testing at a 1.5 and 6 MMBtu/hr scale was performed at thermo Power Corporation during the first phase. Also during the first phase, analytic modeling was performed to guide the design modifications evaluated in the experimental testing. Toward the end of the first phase, John Zink Company entered the program to participate in the design, evalu… more

Materials development and field demonstration of high-recycled-content concrete for energy-efficient building construction

Description: The project developed high-recycled-content concrete material with balanced structural and thermal attributes for use in energy-efficient building construction. Recycled plastics, tire, wool, steel and concrete were used as replacement for coarse aggregates in concrete and masonry production. With recycled materials the specific heat and thermal conductivity of concrete could be tailored to enhance the energy-efficiency of concrete buildings. A comprehensive field project was implemented which … more

MICROBIAL TRANSFORMATIONS OF PLUTONIUM AND IMPLICATIONS FOR ITS MOBILITY.

Description: The current state of knowledge of the effect of plutonium on microorganisms and microbial activity is reviewed, and also the microbial processes affecting its mobilization and immobilization. The dissolution of plutonium is predominantly due to their production of extracellular metabolic products, organic acids, such as citric acid, and sequestering agents, such as siderophores. Plutonium may be immobilized by the indirect actions of microorganisms resulting in changes in Eh and its reduction f… more
