The Protocol to the 1979 Convention on Long-Range Transboundary Air Pollution Concerning the Control of Emissions of Volatile Organic Compounds or Their Transboundary Fluxes (known as the Volatile Organic Compounds Protocol or the VOC Protocol) is a protocol to the Convention on Long-Range Transboundary Air Pollution which aims to provide for the control and reduction of emissions of volatile ...
The definitions of VOCs used for control of precursors of photochemical smog used by the U.S. Environmental Protection Agency (EPA) and state agencies in the US with independent outdoor air pollution regulations include exemptions for VOCs that are determined to be non-reactive, or of low-reactivity in the smog formation process.
A fluidized bed concentrator for VOC control at Honda Manufacturing of Alabama. [1] A fluidized bed concentrator (FBC) is an industrial process for the treatment of exhaust air. The system uses a bed of activated carbon beads to adsorb volatile organic compounds (VOCs) from the exhaust gas. Differently from the fixed-bed or carbon rotor ...
Paint and solvents give off volatile organic compounds (VOCs) as they dry. Lead paint can degenerate into dust and be inhaled. [112] [113] Intentional air pollution is introduced with the use of air fresheners, incense, and other scented items. Controlled wood fires in cook stoves and fireplaces can add significant amounts of harmful smoke ...
In a recent study, it took 4 hours to for the air stripper to reach an equilibrium of efficiency in removing NH3-N elements, topping off at an 81.9% removal rate. Comparatively, only 30.7% of NH3-N elements were removed at 10 minutes, suggesting that removal of contaminants of water correlates with the amount of time spent air stripping.
On the flipside, an Eco mode will shut off the fan if the air has been good (blue light) for 30 minutes, to help conserve energy, and starts up again if the quality of the air takes a turn for the ...
Thermal oxidizers are typically used to destroy hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from industrial air streams. These pollutants are generally hydrocarbon based and when destroyed, via thermal combustion, they are chemically oxidized to form CO 2 and H 2 O. Three main factors in designing the effective thermal ...
Air sparging, also known as in situ air stripping [1] and in situ volatilization is an in situ remediation technique, used for the treatment of saturated soils and groundwater contaminated by volatile organic compounds (VOCs) like petroleum hydrocarbons, [2] a widespread problem for the ground water and soil health.
