VOLATILE ORGANIC COMPOUND (VOC) EFFLUENT STREAMS ARE A SERIOUS AIR POLLUTION PROBLEM. CONTROL TECHNOLOGIES FOR VOCS HAVE BEEN OXIDATION OR CARBON ABSORPTION BUT RECENTLY MEMRANES HAVE SHOWN EFFECTIVENESS. PRESENT MEMBRANE PROCESSES WORK BY PREFERENTIALLY PASSING VOCS (VERSUS AIR) THROUGH THE MEMBRANE AND THEN COMPRESSING AND CONDENSING OUT DOWNSTREAM VOCS. ADVANTAGES OF THIS MEMBRANE PROCESS INCLU ...

Automobile three-way catalyst (TWC) are quite efficient at steady state operatingtemperature typically destroying 98% of incoming hydrocarbons (HCs) and carbonmonoxide (CO). However, up to 80% of emissions occur during the first fewminutes of Federal Test Procedure when the engine is running rich, the engine iscold and TWC has not reached light-off temperature. To significantly reduce HCsand CO ...

Ozone treatment of wastewater to destroy organic contaminants prior to discharge into the environment is an extremely effective advanced oxidation technology. To date the use of this powerful technology has been limited in part by the relatively high capital costs of an efficient ozone to water, gas-liquid, mass transfer system. Existing ozone injection devices must overcome the inherently low m ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

Not Available Makel Engineering Inc. proposes to develop a compact, rugged, smart sensor module capable of measuring multiple gas species and physical parameters. The sensor module will provide measurement of hydrogen, oxygen, ambient pressure, and temperature. This mu

There is a recognized need for more effective and economical treatment processes for oily bilge waters. Direct filtration through currently available ultrafiltration (UF) membranes is a mechanically simple process that can provide excellent effluent quality. A limitation to more extensive use of this technology is the tendency of the hydrophilic membranes currently used to foul in the presence of ...

The 1990 Federal Clean Air Act mandated the incorporation of oxygenates into gasoline in ozone and carbon monoxide nonattainment areas. Methyl tertiary butyl ether (MTBE) is the oxygenate of choice due to economic and supply considerations. Despite federal and state programs to improve handling of gasoline and other fuels in pipelines, underground and above-ground storage tanks, and other transpor ...

Fugitive emissions of volatile organic compounds (VOCs) from gasoline marketing facilities continues to be an energy, safety, and environmental issue. Beginning in model year 2000, all vehicles are required to have an onboard refueling vapor recovery (ORVR) system, which will increase fugitive emissions from refueling stations because of the interface between ORVR vehicles and gasoline station und ...

Diesel generator sets (gen-sets) are used routinely to supply electrical power. Hospitals, businesses, and small communities use gen-sets to help reduce costs by load leveling and provide emergency power during blackouts (either scheduled or unscheduled). Recent power outages in California have led to large increases in the purchase of gen-sets, primarily for providing emergency power. In addition ...
