  • Removal of VOCs from Spent Aerosol Cans.

    There are over three billion aerosol cans manufactured in the U.S. annually, 60% of which are consumed by households. Many of the products contained in these cans, such as paint products, light lubricants, starting fluids, polishes and waxes, and cleaners, contain substantial amounts of volatile organic compounds (VOCs) as solvents and include flammable propellants. As a result, partially empty ...

  • The greening of aerosol propellants

    Chemviron Carbon have pioneered the use of specially selected activated carbons for the storage and delivery of compressed aerial gases such as carbon dioxide and nitrogen. There are many potential gas storage/delivery applications relating to this technology, including as an environmentally friendly alternative to traditional aerosol propellants - see attached article. The technique can also ...

  • Global aerosols studied by NILU

    Aerosols scatter and absorb solar radiation and thereby influence the radiation in the atmosphere and the global climate. To understand the climate system and the ongoing climate change it is important to know the distribution of aerosols in the atmosphere. Satellites provide an extremely useful tool to study this distribution, especially since it is very inhomogeneous with respect to ...

  • Aerosol filtration in nanofiber filter media

    Nanofiber filter media are used in air filter applications where a compact filtration system with very high overall and fractional efficiency and low initial pressure drop  is required.  Moreover, because the aerodynamic drag force on nanofibers is very low compared to the drag on the large dust particles collected on the nanofiber media, this media is ideal for application to ...

  • Messing with the monsoon: Study: Manmade aerosols can alter rainfall in the world’s most populous region

    Original story at MIT  On the Indian subcontinent, the widespread burning of firewood, coal, agricultural waste, and biomass for energy disperses black carbon particulates into the atmosphere. These manmade aerosols not only pollute the air, but also form an “atmospheric brown cloud” that’s disrupting the local ...

  • Particulate matter, halogen and aerosols - Case Study

    Example: Production of anodes for aluminium smelters as well as electronic industry (TFT-LCD) Similar tasks: Carbon and graphite industry, smelting of aluminium, coating of metals An anode producer has several ring furnaces to stabilise the anodes by carbonization for later processing in a melting bath. The hot exhaust gases pass through double walls in between the anodes where the gases ...

  • Can protective garments be wearable filters?

    Protective garments for medical, civilian safety and military applications range from disposable lightweight fabrics to multilayered fabrics and laminated barrier materials, depending upon the nature of the contamination that threatens the wearer. Usually, only full barrier garments, such as the Level A liquid splash protective garments provide full protection from aerosols, and this is due to ...

  • Modelling the influence of dimethyl sulphide on aerosol production in the marine boundary layer

    It has been postulated that dimethyl sulphide (DMS) emissions from the oceans can produce new condensation nuclei and eventually cloud condensation nuclei. Thus, DMS may have a significant influence on the Earth's radiation budget. A study of this postulate has been conducted for marine boundary layer conditions using a newly developed chemistry–aerosol–cloud (CAC) modelling system. The CAC ...

  • Advantages of using the Ecotech three wavelength nephelometer for aerosol measurements

    The measurement of the scattering properties of aerosols is limited by the errors introduced by typical single wavelength integrating nephelometers. These limitations, however, can be reduced by implementing the features of the Ecotech Three Wavelength Integrating Nephelometer. These limitations are predominantly contributed by particle size, relative humidity, Lambertian distribution of the ...

  • Urban indoor-outdoor aerosol measurements in Portugal and the global warming scenario

    Aerosols play a major role both in climate change and air quality. They affect climate by interfering with radiative transfer and the atmospheric temperature. Aerosol particulate matter has also been associated with various adverse health effects. Aerosol particles' number and size distributions were measured inside and outside the houses in the urban areas of Evora and Lisbon in Portugal. The ...

  • Portable Dust Collectors can be very useful

    Thousands of industrial and commercial settings worldwide use portable dust collectors. Processes that create fumes, dust, mist or smoke require this system, as it is not only essential to remove the dust, but also ensures both the employees and work environment are safe. Design of a Portable Dust Collector ...

  • Modelling and simulation of containment retention factor for can-type containment

    Severe accidents cause the failure of fission product barriers and allow the fission products to escape into the environment. The containment is the last barrier for fission products. Thus, containment spray system, heat removal system, recirculation filtration system, Containment Filtered Venting System (CFVS) and containment exhaust filtration system are installed in the containment to ...

  • Methods to assess carbonaceous aerosol sampling artifacts for IMPROVE and other long-term networks

    Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) adsorb to quartz fiber filters during fine and coarse particulate matter (PM2.5 and PM10, respectively) sampling for thermal/optical carbon analysis that measures organic carbon (OC) and elemental carbon (EC). Particulate SVOCs can evaporate after collection, with a small portion adsorbed within the filter. Adsorbed ...

  • Detection of Airborne Viruses in a Pediatrics Department Measured Using Real-Time qPCR Coupled to an Air-Sampling Filter Method

    Children are vulnerable to viral infections. The study discussed in this article investigates the possibility of aerosol transmission of viruses in children under age 18 in the pediatrics department of a medical center in Taipei, Taiwan. After first using the filtration method to collect viral aerosols, the authors combined it with real-time quantitative polymerase chain reaction (qPCR) to detect ...

  • Tailored nanostructures for microgassensors by flame spray pyrolysis

    Integration of nanoparticle synthesis and deposition in micro-machining processes is a mandatory step toward development of nanodevices. Indeed, large scale production of tailored particles is achievable in aerosol reactors. Direct deposition from the aerosol leads to formation of nanostructured layers avoiding the cumbersome steps of wet-methods. Nevertheless, improvement of nanoparticle ...

  • Variations in tropospheric submicron particle size distributions across the European continent 2008–2009

    Cluster~analysis of particle number size distributions from~background sites across Europe~is presented. This generated a total of nine clusters of particle size distributions which could be further combined into two main groups, namely: a south-to-north category (four clusters) and a west-to-east category (five clusters). The first group was identified as most frequently being detected inside ...

  • A preliminary review of gas-to-particle conversion monitoring and modelling efforts in the USA

    Ammonia and inorganic acid gases emitted from livestock and poultry operations, manure treatment, handling and application can affect air quality by the formation of secondary fine particles. The process of gas-to-particle conversion (GTPC) of relatively short-lived gaseous ammonia to more persistent fine particles can affect local and regional air quality far away from the agricultural sources. ...

  • Monitor Organophosphorus Pesticides in Air, Using ORBO-49P Tubes and Capillary GC

    A sampling tube containing Supelpak-20 resin and a glass fiber filter effectively adsorbs and releases five organophosphorous pesticides (chlorpyrifos, diazinon, dichlorvos, malathion, parathion) in vapor or aerosol form in air.  At a sampling rate of 1L/min, 8 hour samples can be taken for all of these pesticides except malathion.  Short term (15 min) samples can be taken at the same ...
