THE CONTROL OF VOLATILE ORGANIC CONTAMINANT (VOC) EMISSIONS FROM INDUSTRIAL PROCESSES AND FUEL SOURCES IS AN IMPORTANT ENVIRONMENTAL PROBLEM. STRINGENT REGULATIONS HAVE BEEN ENACTED THAT WILL LIMIT SUCH EMISSIONS, HEIGHTENING THE NEED FOR SMALL, SIMPLE UNITS THAT CAN RECOVER VOCS AND RETURN THEM AS REUSABLE COMPOUNDS. CURRENT VOC-REMOVAL TECHNOLOGIES, SUCH AS INCINERATION, CARBON ADSORPTION, AND C ...

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 ...

REMOVAL OF TOXIC METALS FROM WASTEWATER STREAMS HAS BECOME A PROBLEM OF INCREASING NATIONAL IMPORTANCE, AS A RESULT OF INCREASING CONCERN FOR OUR ENVIRONMENT, AND INCREASINGLY STRINGENT WASTE DISPOSAL REGULATIONS. CHROMATOCHEM, INC., HAS DEVELOPED AN ECONOMICAL AND EFFECTIVE NEW TECHNOLOGY FOR THE REMOVAL OF LOW LEVELS OF TOXIC METAL IONS FROM WASTEWATER STREAMS, USING SOLID PHASE EXTRACTION (SPE) ...

COALITION TECHNOLOGIES, LTD., (CTL) RESEARCH HAD IMPROVED A SIMPLE GAS PHASE TREATMENT (SULFONATION) OF WASTE RUBBER AND PLASTICS. RESULTS FROM LABORATORY SCALE EXPERIMENTS DONE AT MICHIGAN STATE UNIVERSITY HAVE SHOWN THAT CONCRETE MADE FROM SULFONATED RUBBER AND PLASTIC PROVIDED BY CTL HAS IMPROVED IMPACT RESISTANCE AS MEASURED BY ASTM STANDARD TESTS. IN MANY CASES, WASTE PLASTICS AND RUBBER ARE ...

MANY CONTAMINANTS OF CONCERN AT HAZARDOUS WASTE SITES ARE DIFFICULT TO TREAT BECAUSE OF THEIR CHEMICAL AND PHYSICAL CHARACTERISTICS. CONSTITUENTS WHICH HAVE LOW VAPOR PRESSURE, LOW WATER SOLUBILITY, AND LOW POTENTIAL FOR BIODEGRADABILITY ARE NOT CANDIDATES FOR MANY TECHNOLOGIES. METALS ARE A PRIME EXAMPLE AS ARE POLYCHLORINATED BIPHENYLS (PCBS). THE PROPOSED TECHNOLOGY IS A COLD MIX ASPHALT EMULSI ...

THERE ARE PRESENTLY VAST STORES OF CHLOROFLUOROCARBONS (CFCS) AND BROMOCHLOROFLUOROCARBONS (HALONS) IN USE AS REFRIGERANTS, FIRE SUPPERSSANTS, CLEANING AGENTS, SOLVENTS, PROPELLANTS AND FOAMING AGENTS. SINCE THEY POSE A SERIOUS THREAT TO THE STRATOSPHERIC OZONE LAYER, THEY MUST BE REMOVED FROM SERVICE, AS SPECIFIED IN THE MONTREAL PROTOCOL AND NEW FEDERAL REGULATIONS. CONSEQUENTLY, IT WOULD BE OF ...

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 (
