  • Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy

    For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

  • Hydrochemical characterization of a river affected by acid mine drainage in the Iberian Pyrite Belt

    This paper addresses the modelling of the processes associated with acid mine drainage affecting the Trimpancho River basin, chosen for this purpose because of its location and paradigmatic hydrological, geological, mining and environmental contexts. By using physical-chemical indicators it is possible to define the contamination degree of the system from the perspective of an entire river ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Characterisation of ambient benzene, toluene, ethylbenzene and m-, p- and o-xylene in an urban traffic area in Bangkok, Thailand

    Ambient Volatile Organic Compounds (VOCs) were examined in a heavy traffic urban area in Bangkok, Thailand, on focusing monoaromatic compounds of benzene, toluene, ethylbenzene, m-, p- and o-xylene (BTEX). Passive samplers were used to measure ambient BTEX concentrations in the environment close to very congested roads. Prior to the measurement, the validity of passive sampler performance was ...

  • 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 ...

  • Border emissions monitoring program case study

    Upwards of four million trucks enter the U.S. each year through various southern port crossings in California, Arizona, New Mexico and Texas. Scientific studies at congested US-Mexico border crossings suggest that cross-border truck emissions are contributing to air pollution problems in border communities. Officials expect the problem to become increasingly severe and widespread when the North ...

  • Forklift CO Emissions - Case study

    Measuring Exhaust Gases From Forklift Engines Many forklift trucks have internal combustion engines that burn propane, natural gas, diesel, or other fossil fuels. A portable combustion gas and emissions analyzer can be used to optimize combustion efficiency & maximize fuel savings, identify and quantify sources that can adversely affect safety and comfort in the work environment, ...

  • Increasing efficiency and safety of aluminium smelters – Case Study

    Energy consumption in aluminium smelters The basis for all modern primary aluminium smelting plants is the same: Aluminium oxide (Alumina) is dissolved in an electrolytic bath of molten cryolite (sodium aluminium fluoride) within a large carbon or graphite lined steel container known as a "pot". An electric current is passed through the electrolyte at low voltage, but very high ...

  • Emissions monitoring according to QAL1 - Case Study

    Application A chemicals company produces boron carbide from the raw materials boric oxide and carbon. Boron carbide powder is used for sintering and hot pressing. In other applications boron carbide is used as fi ller material for plastics, metals and concrete or, when used as a material component, increases the wear resistance of electrodes. The production process takes ...

  • 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 ...

  • Don’t Let the Welding Fume Plume Make You Sick

    What’s at Stake? Welding poses a unique combination of both safety and health risks to more than 500,000 workers in a wide variety of industries. The risk from fatal injuries alone is more than four deaths per thousand workers over a working lifetime. What’s the Danger? The fume plume is the clearly visible column of fume that rises directly ...
