  • Carbon Monoxide Levels along Roadway

    This paper predicts and compares the carbon monoxide (CO) concentration levels along Sembulan Road for years 2004 and 2014 using CAL3QHC air dispersion model at two major locations, i.e., at Sembulan Roundabout and Sutera Harbour Intersection, Kota Kinabalu, Sabah, Malaysia. The CO concentration “hot-spots” were also identified at Sutera Harbour Intersection, and the highest maximum 1-hr average ...

  • High Resolution FTIR Analysis of Carbon Monoxide (CO) Gas

    FTIR is being used for analysis of gases in various industries, such as the gas manufacturing industry where it is used for production management, and for gas monitoring in such fields as chemical manufacturing and semiconductor manufacturing, etc. When conducting gas analysis by FTIR, the resolution and gas cell path length must be selected depending on the concentration and peak shape ...

  • A statistical model for predicting carbon monoxide levels

    This paper presents a statistical model that is able to predict carbon monoxide (CO) concentrations as a function of meteorological conditions and various air quality parameters. The experimental work was conducted in an urban atmosphere, where the emissions from cars are prevalent. A mobile air pollution monitoring laboratory was used to collect data, which were divided into two groups: a ...

  • Assessing the impact of air pollution controls on carbon monoxide reduction: the case of Taiwan

    An inevitable external effect of economic growth, especially for countries in the early stages of growth, is air pollution. The Taiwan experience is a case in point. To control the pollution, Taiwan created the Environmental Protection Administration. This paper assesses the impact of the administration's abatement policy on a primary component of air pollution, carbon monoxide. Using recent ...

  • Simulation of the impact on carbon monoxide concentration resulting from replacing a signalised intersection with a roundabout

    This work studies the impact of the substitution of a traffic light for a modern roundabout on carbon monoxide concentration. The estimate of CO concentration is made by means of the CAL3QHC dispersion model, considering only passenger vehicles as emitting sources. Local traffic and meteorological parameters had been adopted and the emission factors had been estimated using CMEM emission model. ...

  • 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 ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Statistical analysis of urban air-pollution data in the Athens basin area, Greece

    Air pollutant concentrations recorded in the Athens basin area by a network of stations are analysed and examined to estimate the typical behaviour of the air pollutants, especially with regard to daily, weekly and annual periodicities and meteorological dependencies. Also, an attempt is made to predict daily and monthly concentrations by utilising a statistically based model, that is, a multiple ...

  • Sensitivity analysis in a simulated auto thermal Natural Gas reforming process

    Auto Thermal natural gas Reforming (ATR) is one of the mostly used conventional hydrogen generation technologies by the highly developed countries. ATR reactors do not need any direct or indirect heat exchanger, and that is why they are more compact and so preferable than the other reformers. In this study, a process including reformers, carbon dioxide sequestration and a cryogenic separation ...

  • Case study - Carbon fibre: furnace & oven emission control

    Overview A carbon fiber company in China was faced with the challenge of selecting an emission control system for a new pilot line at their specialty fiber products facility. The line would include furnaces and three ovens, both of which would emit Carbon Monoxide (CO), Ammonia (NH3) and lethal amounts of Hydrogen Cyanide (HCN).   Action ...

  • Combustion, performance and emission analysis of diesel engine fuelled with methyl esters of Pongamia oil

    The methyl esters of vegetable oils, known as biodiesel are increasingly becoming popular because of their low environmental impact and potential as a green alternative fuel for diesel engine, and that they would not require significant modification of existing engine hardware. Methyl ester of Pongamia oil (PME) is derived through transesterification process. Experimental investigations have been ...

  • The comparative analysis of diesel engine combustion and emission parameters fuelled with palm oil methyl esters and its diesel blends

    In this work, the combustion and emission characteristics of a direct injection compression ignition engine fuelled with diesel-Palm Oil Methyl Ester (POME) blends are investigated. This study shows that the ignition delay decreases with increase in the POME addition. The maximum rate of pressure rise and maximum rate of heat release decreases with increase in POME addition at all loads. As the ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Study of the weekday-weekend variation of air pollutants in a typical Mediterranean coastal town

    A study of the air pollution in the Greek coastal town Volos was performed using the available data of the last ten years. Quantile analysis showed that ozone concentrations during weekends were higher by 5–10% in comparison to those on weekdays, while the inverse was observed for the other pollutants, indicating the occurrence of the so called 'weekend effect'. Analysis of the maximum values of ...
