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 ...

NEW METHODS ARE NEEDED THAT RAPIDLY, ECONOMICALLY, AND EFFICIENTLY TREAT WASTEWATERS FOR REUSE OR DISPOSAL. ESTABLISHED WASTEWATER TREATMENT TECHNOLOGIES ARE EXPENSIVE AND CAN BARELY BE STRETCHED TO MEET THE REQUIREMENTS FOR WATER REUSE IN A PLANT OR DISCHARGE UNDER ENVIRONMENTALLY ACCEPTABLE CONDITIONS. OXIDIZING ORGANIC POLLUTANTS IN SITU ON ELECTROCATALYSTS DRIVEN BY ALTERNATING CURRENT. A MIXE ...

Billions of gallons of oily wastewaters are generated daily by a variety of industrial sources. A large fraction of these are oil/water emulsions for which current treatment technologies are often costly and ineffective. Although such emulsions can be separated using crossflow filtration technology, conventional crossflow membranes typically are uneconomic for performing such treatment due to st ...

Vapor permeation with highly permeable and organic-selective membranes is becoming an increasingly popular technique for preventing VOC emissions that are generated by a variety of stationary sources, including solvent and surface coating operations, gasoline storage operations, and printing operations. A limitation of current vapor permeation (VP) processes is the upper temperature limit for pol ...

MICROWAVE LANDING SYSTEM WILL INCREASE THE SAFETY OF TERMINAL AREA NAVIGATION, AND THE EFFICIENCY OF AIRSPACE UTILIZATION AT CONGESTED AIRPORTS WITH THE USE OF NAVIGATIONSYSTEMS BLENDING MLS POSITION INFORMATION WITH THAT PROVIDED BY ON-BOARD SENSORS. THE OBJECTIVE OF THISSTUDY IS TO DEVELOP LOW COST MLS BASED NAVIGATION SYSTEM FOR USE ON GENERAL AVIATION, COMMUTER, AND SHORT-HAUL TRANSPORT AIR CR ...

CSE PROPOSES TO APPLY ITS DEMONSTRATED, PATENDED PROTOTYPE PRESSURE-SENSOR TECHNOLOGY TO HBRID 3 FACE AND OTHER ATD AREAS, ALLOWING ACCURATE RECORDING TRIAXIAL ANGULAR ACCELER ATIONS AS WELL AS AREA-PRESSURE-TIME HISTORIES ON HEAD, FACENECK, THORAX, ABDOMEN, KNEE, AND ANY OTHER ATD REGION. PRESSURE SENSORS WILL CONSIST OF SEGMENTED STRIPS, VESTS, ORGLUED-ON PATCHES. DATA WILL BE PROCESSED BY MDAS ...

THE ECONOMIC USEFULNESS AND THE RANGE OF INFOMATION THAT CANBE OBTAINED FORM ON-LINE INFRARED GAS ANALYSIS IS LIMITED SINCE A COMPLEX AND UNRELIABLE EXTRACTIVE SAMPLING SYSTEM ORA DEDICATED SPECTROMETER IS NEEDED AT EACH SENSING POINT IN THE PROCESS. THIS PROGRAM INTENDS TO DEMOSTRATE THE FEASIBILITY OF TRANSMITTING THE IR SPECTRAL INFORMATION VIA OPTICAL FIBERS DRAWN FROM NEW MATERIALS--HEAVY MET ...

The development of an instrument for continuously monitoring SO2 levels in fluegas is proposed. The SO2 will be detected by means of an electrochemical sensorcell, which operates in a three-electrode potentiostatic mode. The proposedinnovation is develop-ment of an advance sensor cell which uses a high-temperature solid polymer eleobjectives of the proposed program are 1) identification of poten ...
