  • Flow measurement with PicoFlow - Case Study

    Application A waste incineration plant produces exhaust gases during the incineration process. These gases need to be cleaned. Therefore hearth furnace coke is used continuously and, if needed, lime hydrate. Both materials are stored in silos. Via a rotary valve the two materials are blown from the storage places into a conveying air fl ow and thereby reach the ...

  • Dusty monitors quality of pressing tools - Case Study

    Application A manufacturer of food supplements produces tablets with different ingredients mechanically via pressing tools. The pressing tools eventually wear down during production. As the tools wear down there is an increase of dust particles created in the exhaust air of the machines. In this application our customer wants to measure the dust content in the exhaust air of ...

  • NH3 Slip Monitoring in Fluidized-bed Catalytic Cracking Using the LDS 6 Gas Analyzer – Case Study

    Fluidized catalytic cracking (FCC) units are used in refineries to convert low value heavy oils into more valuable lighter compounds. Cracking units are sources of emissions of pollutants (e.g. NOx) and must comply with concentration permits set by local or federal authorithies. Modern technologies are applied to reduce the content of pollutants and to monitor certain gas compounds (here: NH3) in ...

  • Real-world vehicle emissions as measured by in situ analysis of exhaust plumes

    Abstract We conducted a 60-day roadside measurement campaign on a busy street in Münster, Germany, during summer 2016. We used gas and particle concentration measurements with high temporal resolution (10 Hz) to quantify both the emission ratios of nitrogen oxides per carbon dioxide (NOx/CO2) for over 70,000 individual exhaust plumes as well as the emission ratios ...

  • Critical Monitoring of Forklift Emissions and Warehouse Ambient Air Quality - Case Study

    Our team of experts has been hard at work and has just released an industry-leading report detailing Forklift Emissions in Warehouses: The main objectives of this study were to investigate the effects of different engine conditions on exhaust gas emissions and to observe the effect that forklift emissions have on the ambient air quality of the warehouse.             ...

  • Emission reduction methods and split fuel injection in a marine four-stroke engine

    Abstract The new emission legislation for sea-going vessels issued by the International Maritime Organization (IMO) requires drastic reduction in exhaust gas nitrogen oxides (NOX), and the combination of different primary methods can be an interesting solution without increasing remarkably the machinery. In this paper, the Miller cycle and the dilution with exhaust gas ...

  • Effect of turbulence intensity on PM emission of heavy duty diesel trucks – Wind tunnel studies

    Abstract Stringent emission regulations have forced drastic technological improvements in diesel aftertreatment systems, particularly in reducing Particulate Matter (PM) emissions. The formation and evolution of PM from modern engines are more sensitive to overall changes in the dilution process, such as rapidity of mixing, background PM present in the air. These technological ...
