The problem addressed in this project is the need to monitor oxides of nitrogen(NOx, ie NO and NO2) levels in the combustion gases of stationary sources suchas power plants in order to facilitate on-line control of the scrubbers that willbe used to remove those pollutants. Since the measurements are in the parts permillion range, simpler and less expensive instruments than those currently used,su ...

Infrared tunable diode laser spectrometers provide a highly effective means of measuring trace concentrations, with either remote sensing or with advective sampling. It is often desirable to measure more than one trace gas at a time. This is especially true when gas emissions are strongly correlated, such as in combustion emissions where measuring both the CO2 concentration and another minor con ...

SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

DIESEL ENGINES PLAY AN IMPORTANT ROLE IN THE UNITED STATES ECONOMY FOR POWER GENERATION AND TRANSPORTATION. HOWEVER, NOX AND SOOT EMISSIONS FROM BOTH STATIONARY AND MOBILE DIESEL ENGINES ARE A MAJOR CONTRIBUTOR TO AIR POLLUTION. MANY ENGINE MODIFICATIONS AND EXHAUST-AFTER-TREATMENT DEVICES HAVE BEEN PROPOSED AND TESTED TO REDUCE THE NOX AND SOOT EMISSIONS FORM DIESEL EXHAUSTS. SIMPLE TECHNIQUES FO ...

THE OBJECTIVE OF THE PHASE I EFFORT IS TO DEVELOP, IMPLEMENT, AND EVALUATE AN OPERATOR-BASED METRIC FOR ASSESSING FUTURE CONTROL ROOM AUTOMATION SYSTEMS FOR COMMERCIAL NUCLEAR PLANT OPERATIONS. THE FOCUS WILL BE ON AUTOMATION'S IMPACT ON OPERATOR UNDERLOAD AND SITUATION AWARENESS (SA). THE APPROACH COMBINES AN OPERATOR/SYSTEM BEHAVIORAL REPRESENTATION IMPLEMENTEDIN SOFTWARE, WITH A PROCEDURAL METH ...

PHASE I WILL DETERMINE THE FEASIBILITY OF A SIMPLE, COST EFFECTIVE PROCESS FOR THE ON-SITE REGENERATION AND REACTIVATION OF SPENT CARBONS. THE SPENT CARBONS MAY CONTAIN HAZARDOUS COMPONENTS, BOTH ORGANIC AND INORGANIC. THE REGENERATION IS ACCOMPLISHED WITH AN INNOVATIVE THERMAL PROCESS WHICH PRODUCES HIGHLY REACTIVE CHEMICAL SPECIES AT HIGH TEMPERATURE ON THE SURFACE OF THE CARBON MATRIX WHERE THE ...
