Current anaerobic digester systems are designed for capturing energy from waste from large heads of farm animals. GHD, Inc., a leading manufacturer of anaerobic digesters, has stated that a minimum dairy heard size for economical implementation of a biogas system as 800 cows. These require turbine or diesel generator sets of 100 Kilowatt size and larger, a limiting factor in economically scaling ...

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 ...

NITROGEN OXIDES (NO AND NO2 OR NOX) ARE AMONG THE MOST PERVASIVE AND DIFFICULT EMISSIONS TO CONTROL. ALTHOUGH THE DECOMPOSITION OF THE MAJOR SPECIES (NO) IS THERMODYNAMICALLY FAVORED, THERE ARE NO COMMERCIAL CATALYTICPROCESSES CAPABLE OF DECOMPOSING NOX WITHOUT THE ADDITION OF A REDUCING GAS. THIS IS BECAUSE THE OXYGEN PRODUCED DURING THE DECOMPOSITION REMAINS STRONGLY CHEMISORBED ON THE CATALYST, ...

AUTOMOTIVE CATALYTIC CONVERTERS ARE QUITE EFFICIENT ONCE THEY REACH OPERATING TEMPERATURE, TYPICALLY DESTROYING OVER 98% OF THE INCOMING HYDROCARBONS (HCS) AND CARBON MONOXIDE (CO). HOWEVER, UP TO 80% OF THE EMISSIONS DURING THE FEDERAL TEST PROCEDURE OCCUR DURING THE FIRST FEW MINUTES WHEN THE ENGINE IS RUNNING RICH, THE OXYGEN SENSOR IS NOT YET OPERATIONAL, AND THE CATALYTIC CONVERTER HAS NOT RE ...

THE EMISSION OF HALOGEN CONTAINING POLLUTANTS FROM A VARIETY OF POWER GENERATING, WASTE PROCESSING, CHEMICAL PRODUCTION, AND SOLVENT USING INDUSTRIES IS AN ENVIRONMENTAL CONCERN OF MAJOR SIGNIFICANCE. INORGANIC HALOGEN SPECIES, INCLUDING HYDROGEN CHLORIDE AND HYDROGEN FLUORIDE, REPRESENT MAJOR POTENTIAL HEALTH THREATS TO BOTH HUMAN, ANIMAL, AND PLANT COMMUNITIES. ORGANIC HALOGENATED COMPOUNDS (HOC ...

CADMIUM ELECTROPLATING IN CYANIDE AND OTHER TOXIC CHEMICAL BATHS IS OF SIGNIFICANT ENVIRONMENTAL CONCERN. IN ADDITION, CADMIUM COATINGS RELEASE TOXIC BY-PRODUCTS IN THE ENVIRONMENT DURING THEIR USE AND DISPOSAL. AS A CONSEQUENCE, A UNIQUE AND ECONOMICAL DRY PLATING METHOD HAS BEEN DEVELOPED. UNLIKE CONVENTIONAL PLATING, THIS METHOD WOULD USE NO LIQUID CHEMICALS. THE DRY PLATING CONCEPT UTILIZES A ...
