Emissions of volatile organic compounds (VOCs) and hazardous air polutants (HAPS are a serioud environmental issue. These pollutants are requlated to protect human health and encourage the development of better control technologies. Current technologies to control thses emissions, until better materials are developed, include destructive and/or recovery-based technologies. Implementation of ads ...

Caviton has developed a novel technique for the continuous monitoring of trace metals emissions. This technique is based on a microdischarge light, which is collected by a spectrometer and analyzed. All metals tested to date can b detected and the focus of this Phase II project is to develop a sampling system, carry out laboratory tests, then move to field tests of sampling and analysis. Finall ...

Lead is a soft, low melting point, high density, and inexpensivve material that can be easily shaped. All these attributes have made lead useful in appplications such as bullets, fishing rod sinkers, weights for balancing tires, hunting shots, etc. In spite of all these attractive properties, lead is a major environmental contaminant due to its toxicity. Leaed is toxic and cna be stored in biol ...

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 THREE-WAY CATALYTIC CONVERTER IS THE MOST IMPORTANT DEVICE MAKING TODAY'S AUTOMOBILES COMPLY WITH EXISTING EMISSION LAWS. THE FIRST TWO OR THREE MILES IN A TYPICAL 22-MINUTE, 12-MILE COMUTE IN TODAY'S VEHICLES RESULT IN THE EMISSION OF HALF OF THE TOTAL NON-METHANE HYDROCARBONS, WHICH RESULT IN THE PRODUCTION OF URBAN SMOG, AS WELL AS HALF OF THE TOXIC CO EMISSIONS. THIS OCCURS BECAUSE THE CAT ...

THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...
