Odor Elimination: Rendering - Case Study
Summary In the Rendering Industry, odor control equipment has been in use since the early 1970’s about the same time Anguil was formed and started serving clients with the best available air pollution control equipment. Typical early applications of air pollution control equipment in rendering consisted of a direct fired afterburner for destruction of the organic emissions (odor, ammonia, ...

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 ...

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 ...

Environmental innovation and clean technology: an evolutionary framework
This paper provides a framework for the analysis of clean technology which covers the factors inducing, stimulating and constraining environmental innovations of firms. Such a framework relies on recent empirical and theoretical contributions to environmental innovations. The representation of clean technology draws from several industrial case studies on the reduction of the emissions of ...

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 ...

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 ...

Biofiltration of Ethanol Emissions from Bakery Operations
The management of volatile organic compounds in bakery exhaust gases was identified as a high priority problem by the American Bakers Association in conjunction with their member companies. Biotrickling filter technology was evaluated among other approaches and was selected for a pilot study to control ethanol emissions from a bakery oven exhaust gas stream. Biofilters and biotrickling filters ...

Does emissions trading lead to air pollution hot spots? Evidence from an urban ozone control programme
This study is an empirical investigation into the contentious issue of possible sub-area hot spots caused by emissions trading in a pioneering application of a cap-and-trade market approach to reducing aggregate stationary-source volatile organic compound emissions in the Chicago severe ozone non-attainment region. When sub-areas are defined as populated zip codes, 89 out of 95 affected codes ...

The Ability to Detect From a Distance
Observing this series of photos taken every 30 seconds by OPGAL’s OGI camera (EyeCGas 2.0), shows a significant volatile organic compounds emission (VOCs) event, including methane released into the air. The gas flows through a cold pipe (the black flare structure), and its temperature evens out with the ambient air temperature upon release to the atmosphere. However, since all VOCs emit an ...

Inspection Manual: Federal Equipment Leak Regulations for the Chemical Manufacturing Industry
Untitled Document Abstract The purpose of this manual is to enhance an inspector's ability to conduct more complete and effective inspections at facilities in the chemical industry that are subject to Federal equipment leak regulations. Equipment leak standards are designed to reduce or eliminate emissions of volatile organic compounds (VOCs), volatile hazardous air pollutants ...

Odorous volatile organic compound (VOC) emissions from ageing anaerobically stabilised biosolids
Opportunities for the beneficial re-use of biosolids are limited by nuisance odour emissions. Volatile organic compounds (VOCs) from anaerobically stabilised biosolids were measured to identify compounds that could contribute to the overall odour character of nuisance emissions. Flux hood sampling and chemical analysis were used to identify VOCs emitted from biosolids as they were stored in ...

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 ...

Three-dimensional modelling of photochemical air pollution in Switzerland and comparison with a multi-parcel Lagrangian model
The photochemical smog situation in Switzerland on 29 July, 1993 was simulated using the 3-D grid model UAM (Urban Airshed Model) and the results were compared with those of a multi-parcel Lagrangian model. Sensitivity analyses concerning initial conditions, emissions, deposition, biogenic volatile organic compounds (VOC), and emission reductions were carried out. Results were compared with field ...

Control of VOC emissions from a flexographic printing facility using an industrial biotrickling filter
The study of an industrial unit of biotrickling filter for the treatment of the exhaust gases of a flexographic facility was investigated over a 2-year period with the objective to meet the volatile organic compound (VOC) regulatory emission limits. Increasing the water flow rate from 2 to 40 m3 h−1 improved the performance of the process, meeting the VOC regulation when 40 m3 h−1 were used. An ...

Laboratory waste gas treatment solutions
The target pollutants emitted by the laboratory are ranked in the order of potential emission intensity and control necessity: small molecular gas pollutants, specific organic pollutants (formaldehyde, xylene, methanol), biological pollutants (pathogenic microorganisms and their aerosols) ), odor, other TVOCs (ether, benzene and other macromolecular organic substances), particulate matter. There ...
