Common Treatment Technologies for Nonhalogenated VOCs in Air Emissions/Off-Gases
Three technologies that are most commonly used to treat nonhalogenated VOCs in air emissions/off-gases are carbon adsorption, catalytic oxidation, and thermal oxidation. Carbon adsorption is a remediation technology in which pollutants are removed from air by physical adsorption onto the carbon grain. Carbon is 'activated' for this purpose by processing the carbon to create porous particles ...

Relation between ozone levels and NOx and VOC emissions in the Sao Paulo Metropolitan Area for an episode of August, 1998
At present, major efforts in air pollution control for urban areas are oriented to reduce ozone levels to below standards. Models are a useful tool for air quality assessment and they can help to select the best strategy plan to reduce ozone levels in a polluted area. Like other large cities in the world, Sao Paulo Metropolitan Area (SPMA) has registered high levels of ozone and particulate ...

Methods for the control of oil vapour emissions
There are many oil vapours to discharge from oil containers into the atmosphere in oil operations (such as storage and loading). Two basic concepts are discussed regarding the control of oil vapour emission (OVE). The first is to invent active methods to restrain the OVE. The second is to develop passive tail–end remediation technologies to control the released vapour. Oil vapour recovery ...

Modeling of air stripping from volatile organic compounds in biological treatment processes
The removal of volatile organic compounds from biological treatment processes occurs through several mechanisms. These include biodegradation, adsorption onto solids, and air stripping or volatilization to the atmosphere. Volatilization results in fugitive emissions to the atmosphere, which is largely uncontrolled. Recent regulations have called for increased evaluation and control of inadvertent ...

VOC`s oxidation
Real Decreto 117/2003, dated 31st January related to Volatile Organic Compounds emission limits, due to organic solvents, as well as Law 16/2002, dated 1st July, related to prevention and integrated control of pollution (IPPC), came into force, which will impel many industries to set devices for the treatment and elimination of gases effluents with different organic compounds content. Here, we ...

VOC composition and ozone-forming potential of the exhaust gas of in-use motorcycles
The emission profile of volatile organic compounds (VOC) and the ozone-forming potential (OP) of the exhaust gas of six in-use motorcycles (four 4-stroke- and two 2-stroke-engines) were determined. The motorcycles were tested on a chassis dynamometer in a real-world driving cycle. The analysis involved the C2–C12-hydrocarbons as well as the aldehydes and ketones. Additionally, the regulated THC ...

Odour control with Direct Cold Plasma
Odour emission during the production or processing of food and feed is often an unwelcome side effect. However, by using cold plasma technology, the smell can be reduced up to 95%. Increasingly, feed manufacturers are being required to address the issue of emitting of odour and harmful contaminants into the surrounding community. Local communities, special interest groups and government ...

A Comprehensive Review Of Regenerative Thermal Oxidizers
Within industry today, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new. In response to Congressional guidelines passed in the 1970’s, a number of companies with VOC emissions have been operating air pollution control systems of one type or another for 25 years or more. These guidelines have been revised and added to as the years progressed, ...

Potential of biofiltration for VOCs emission control and safety aspects
Directive 99/13/EC on the emission of Volatile Organic Compounds (VOCs) is impacting on several industries in Italy, as well in other EU countries. Many small enterprises have to invest in new control systems and need to be helped to choose an appropriate and safe technology. As VOCs are highly flammable compounds, high concentrations in emission flows can pose a fire and explosion hazard if ...

Studying the influence of biogenic emissions on AOT40 levels in Europe
It is well known that the uncertainties in determination of biogenic emissions are very large (some authors claim that these emissions are underestimated in certain areas of the world by up to ten times). On the other hand, anthropogenic emissions in some areas of the world have been reduced very considerably during the last two decades (this is especially true for Europe). This fact shows ...

Modeling of packed absorption tower for volatile organic compounds emission control
Development of chemical industry and high vapor pressure of volatile organic compounds (VOCs) have been caused that these materials recently be considered as a source of air pollution. These are different methods for separation of VOC from air that absorption by suitable and selective solvent is an efficient method. In this research, mathematical modeling of a packed absorption tower for ...

Volatile organic compounds emitted from hardwood drying as a function of processing parameters
During the drying of wood, volatile organic compounds are emitted. These emissions contribute, in the presence of nitrogen oxides and sunlight, to the formation of ground level ozone and other harmful photo-oxidants.
