  • Analysis of Motor Vehicle Exhaust Emissions

    A standard Hiden HPR-20 was used for the detection of various gaseous emissions from a motor vehicle. The mass spectrum was complex due to the mixture of air, hydrocarbons and other combustion products. Analysis of this type is important to detect levels of toxic or hazardous species. Such levels are often strictly controlled by local government legislation thereby forming an important target for ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...

  • Controlling particulate emissions

    Cloud chamber technology uses electrically charged water droplets to attract fine particles and remove them from exhaust streams. At the Saint-Gobain Advanced Ceramics Boron Nitride (formerly Carborundum) plant in Amherst, ...

  • Put energy into emission control projects

    Many companies feel pressured to spend the least amount possible to meet environmental regulations, primarily because compliance isn’t a profit generating endeavor. What some environmental and compliance managers fail to realize is that emission control equipment can quickly become a profit decreasing endeavor with this penny wise-pound foolish approach. With mandatory greenhouse gas (GHG) ...

  • On-Vehicle Exhaust Gas Cooling in a Diesel

    ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is ...

  • Carbon Fiber Emission Control Strategies

    Problem Carbon fiber (fibre) and graphite reinforced polymers are materials that have, and will continue to revolutionize the products we use everyday by making them stronger, lighter and more durable. However, the manufacturing process can have serious environmental ramifications and immediate danger to human health if careful consideration is not given to emission control at the ...

  • Trends of exhaust emissions from gasoline motor vehicles in the metropolitan area of Mexico city

    Light duty gasoline vehicles account for most of CO, hydrocarbons and NOx emissions to the urban environment in the metropolitan area of Mexico City. In order to ameliorate air pollution, several control measures have been imposed in the last decade, such as: up-grade of gasoline's quality, stringent environmental standards, and catalytic converters. On the other hand and from the beginning ...

  • Energy efficiency and emission reduction of TPM, PM2.5, and SO2 from natural gas and fuel oil fired boiler exhausts

    Fully 8% of all of Canada’s energy consumption occurs in gas and fuel oil fired boilers in commercial and institutional facilities1, with proportional amounts of greenhouse gases, particulate matter, and other pollutants. Recently particulate matter, and in particular that smaller than 2.5 microns (PM2.5) has garnered specific attention due to attributed health effects as demonstrated by ...

  • Strategies for controlling pollution from vehicular emissions in Beijing

    Beijing is one of the most polluted cities in the world, which is caused by surprising vehicular growth in the past decade. This paper describes the severe situation of vehicular emission pollution in Beijing, and discusses the following strategies for mitigation: improving fuel quality, controlling the exhaust from new vehicles, controlling the emissions from vehicles in use through, e.g., ...

  • Case study - Engine cell exhaust: RTO

    Problem A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also, within this exhaust is a great deal of water vapor ...

  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • A cost-effective method for controlling compost air emissions

    In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

  • Case study - Reactor vent emission control

    OVERVIEW Many chemical and petroleum companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, the ...

  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Case study - Kiln emission control technologies

    Overview A specialty ceramic material manufacturer in the United States operates several custom-built furnaces in their manufacturing process.  Sometimes referred to as kilns, these high-temperature process devices are generally a major source of air pollutants and require an abatement technology to meet environmental regulations with the state or federal agencies.  As is the ...
