NUMEROUS INDUSTRIAL PLANTS ARE SOURCES OF LOW CONCENTRATIONS OF VOLATILE ORGANIC COMPOUNDS (VOC) WHICH ARE EMITTED INTO THE AIR, SOMETIMES IN HIGH FLOWS OF OFFGAS. SOME OF THE OFFGAS STREAMS MAY ALSO CONTAIN FINE PARTICULATE MATTER FROM 10 MICRONS TO THE SUBMICRON SIZE RANGE. THE VOC MAY CONDENSE ON THE FINE PARTICULATE MATTER WHICH, DUE TO ITS SIZE, CAN LODGE DEEP WITHIN THE LUNGS. MOST INDUSTRIA ...

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 OXIDATION OF DILUTE CONCNETRATIONS OF ORGANICS IN AQUEOUS SOLUTIONS USING HYDROGEN PEROXIDE AND/OR OZONE AS THE OXIDANT IN THE PRESENCE OF ULTRAVIOLET (UV) LIGHT HAS BEEN DEMONSTRATED AND IS OFFERED COMMERCIALLY BY SEVERAL CORPORATIONS. PRESENT SYSTEMS SEEM TO BE LIMITED TO LOW CONCENTRATIONS OR ORGANICS (

THIS PROPOSAL PRESENTS A CONCEPT FOR A CHEMICAL MONITOR BASED ON DIFFERENTIAL CATALYTIC REACTIVITIES AND LARGE REACTION EXOTHERMICITIES. THE SIMPLICITY OF THE PROPOSED SENSOR CONCEPT PROMISES AN ECONOMIC AND RELIABLE MONITOR FOR IN-SITU MEASUREMENT OF A VARIETY OF GASES. IN THIS PROJECT, ENVIROCHEM, INC., WILL INVESTIGATE THE APPLICATION OF THIS CONCEPT FOR MEASURING AMMONIA IN FLUE GASES. A SENSI ...

FOSTER-MILLER PROPOSES TO UTILIZE SCRAP PREPREG WASTE AS A REINFORCEMENT IN RECYCLED POLYETHYLENE. BY REINFORCING RECYCLED PLASTICS SUCH AS POLYETHYLENE WITH SCRAP PREPREG AND SUITABLE BINDERS, AN ECONOMICAL USEFUL PRODUCT CAN BE OBTAINED. AT THE SAME TIME, THIS INNOVATION WILL ALSO HELP TO REDUCE 2.5 MILLION POUND/YR OF HAZARDOUS WASTE -- UNCURED PREPREG SCRAP. FOSTER-MILLER IS WORKING WITH A COM ...

THE VAPOR RECOVERY NOZZLE IS AN AIR POLLUTION CONTROL DEVICE WHICH RELATES TO STAGE II EMISSION CONTROL EQUIPMENT DESIGNED TO CAPTURE GASOLINE VAPORS DURING AUTOMOBILE REFUELING AT SERVICE STATIONS. ALTHOUGH STAGE II VAPOR RECOVERY NOZZLES HAVE BEEN IMPROVING SINCE THEIR INTRODUCTION IN 1974, THERE IS A HIGH LEVEL OF PUBLIC DISSATISFACTION WITH THE CURRENT PRODUCTS. THE EXISTING VAPOR RECOVERY NOZ ...

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 ...
