Jet engine test cells are faced with meeting regulations related to NOx emissions and opacity. Based upon reported research results, it appears that the Pulse Induced Plasma Chemical Process (PPCP) could be effectively applied to jet engine test cells for the control of NOx. The process provides high efficiency NOx removal at relatively low temperature without the need for NH3 injection. PPCP can ...

A STEP TOWARD BEING NUMBER ONE IN MATHEMATICS AND SCIENCE EDUCATION BY THE YEAR 2000 (AMERICA 2000 GOAL) AND MAINTAINING REASONABLE SCHOOL BUDGETS CAN BE MADE BY INTRODUCING A LOW COST SYSTEM WHICH WILL BRING THE STATE-OF-THE-ART TECHNOLOGY INTO THE HIGH SCHOOL LABORATORY. THE PLANNED LABORATORY WORKSTATION ADDRESSES THIS NEED, BY TAKING THE STATE OF THE ART TOOLS AVAILABLE FOR RESEARCHERS AND INT ...

STATIONARY SOURCES IN THE U.S. EMIT ABOUT ONE MILLION KG OF MERCURY INTO THE ATMOSPHERE ANNUALLY. MAJOR SOURCES OF THESE EMISSONS ARE FOSIL FUEL COMBUSTIONFACILITIES ANE MUNICIPAL SOLID WASTE INCINERATORS. MUCH WORK IS BEING DONE BY DOE AND INDUSTRY TO CHARACTERIZE THESE EMISSIONS AND TO DEVELOP EFFECTIVE CONTROL MEASURES. CONTINUOUS EMISSIONS MONITORS (CEMS) FOR MERCURY WILL PLAY A SIGNIFCANT ROL ...

IMPROVED FABRIC FILTER PERFORMANCE FOR BOTH THE COLLECTION OF FINE PARTICULATE MATTER (PARTICLES LESS THAN 10 MICRONS) AND TOXIC METAL EMISSIONS FROM FLUEGASES IS IMPORTANT BECAUSE MOST OF THE TOXIC METALS ARE CONCENTRATED IN THIS SIZE RANGE, FINE PARTICLES ARE RESPIRABLE AND THEREFORE POSE A HEALTH RISK, AND FINE PARTICLES ARE EFFECTIVE LIGHT SCATTERERS AND LEAD TO HIGH OPACITY LEVELS. IT IS PLAN ...

THE POTENTIAL ADVANTAGES OF MEMBRANE PROCESSES FOR SEPARATIONS ARE WELL KNOWN. HOWEVER, CURRENT MEMBRANE SYSTEMS HAVE CAPTURED ONLY A SMALL FRACTION OF THE POTENTIAL MARKET, PRIMARILY BECAUSE THEY ARE MADE FROM POLYMERS THAT ARE NOT DURABLE ENOUGH FOR MANY APPLICATIONS, AND THEY DO NOT HAVE SUFFICIENT SELECTIVITY FOR CLEAN SEPARATIONS. PLASMA-POLYMER MEMBRANES OFFER A SOLUTION TO BOTH PROBLEMS. TH ...

DOMESTIC NATURAL GAS PROVIDES AN INCREASINGLY IMPORTANT PORTION OF THE U.S. ENERGY SUPPLY. ESTIMATED U.S. GAS RESERVES ARE ABOUT 1000 TRILLON STANDARD CUBIN FEET (SCF)--OR ABOUT 1000 QUADS. FULLY 25% OF THE ESTIMATED U.S. NATURAL GAS RESERVES ARE CONTAMINATED WITH NITROGEN (N2) TO THE EXTENT THAT THE GAS CANNOT BE USED WITHOUT PROCESSING TO REDUCE THE N2 CONCENTRATION. NO TECHNOLOGY EXISTS TODAY F ...

THE MATERIALS CURRENTLY USED FOR RADIO FREQUENCY (RF) FEEDTHROUGH INSULATORS ARE INADEQUATE FOR FUTURE FUSION DEVICES SUCH AS THE INTERNATIONAL THERMONUCLEAR EXPERIMENTAL REACTOR (ITER). THESE MONOLITHIC CERAMICS WILL LOSE THEIR DIELECTRIC STRENGTH, AND SWELL IN THE NEUTRON FLUENCES EXPECTED IN ITER. THIS MAKES THEM EXTREMELY SUSCEPTIBLE TO BRITTLE FRACTURE, WHICH CAN LEAD TO CATASTROPHIC FAILURE ...

We propose to develop a general purpose computer code for calculating the scattering from antennas on an aircraft, which is described by a CAD file. The scattering contribution will include both the passive structure mode and active irradiation mode, calculcated by a hybrid of a high-frequency ray technique and a rigorous finite element technique. The proposed code will be made compatible with the ...

RESEARCH WILL BE CONDUCTED BY HICHEM CORPORATION, TO DEVELOP A NEW TECHNOLOGY FOR PYROLYSIS OF SCRAP TIRES. DISPOSAL OF USED TIRES IS A BIG PROBLEM IN THE WORLD, ESPECIALLY USA, SINCE MORE THAN 2.5 MILLION TIRES ARE DISCARDED EACH YEAR. MOST OF THESE TIRES ARE DISPOSED IN LANDFILLS. PYROLYSIS OF SCRAP TIRES HELPS TO RECOVER AND REUSE MOST OF THE VALUABLE CHEMICAL AVAILABLE IN TIRES. PYROLYSIS OF S ...

THE REMARKABLE SUCCESS ACHIEVED FOR PRODUCING GAS FROM COAL SEAMS INTHE SAN JUAN BASIN CAN BE ATTRIBUTED LARGLEY TO UTILIZATION OF THE INNOVATIVE OPEN-HOLE CAVITATION (OHC) TECHNIQUE. NEARLY 70% OF THE SAN JUAN BASIN COALBED METHANE IS PRODUCED FROM OHC WELLS EVEN THOUGH THEY ONLY ACCOUNT FOR 20% OF THE PRODUCING COALBED METHANE WELLS. MOST OHC WELLS COMPLETED WITH OHCOUTPERFORM HYDRAULIC FRACTURE ...
