  • EDXRF Analysis of Sulfur and Other Elements in Oil

    The concentrations of sulfur substances in fuel oil, which greatly contribute to air pollution and acid rain, are regulated by law in many countries, and these regulations are becoming stricter with the growing concern about their impact on the environment and the consequences for society. Here, using the easy-to-operate EDX-720 energy dispersive X-ray fluorescence spectrometer, we determined the ...

  • Sulfur Compounds Analyzer MEXA-1170SX

    The MEXA-1170SX is a continuous gas analyzer for sulfur compounds existing in engine emissions. It can measure SO2 concentration and the amount of total reduced sulfur compounds (TRS), such as H2S, separately. It can also measure the total sulfur compounds (TS) that contains both gaseous compounds and liquid compounds in PM, such as SO3. By utilizing ultra-violet fluorescence (UVF) method and ...

  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • Quantification of Ultra Low Sulfur in Diesel by Xray Fluorescence

    ASTM International has developed a number of testing methods for determination of sulfur content that focus on a variety of analyzer technologies but ASTM Method D4294 is the one that focuses on the use of energy dispersive x-ray fluorescence (EDXRF); which offers a relatively low cost analysis method that achieves fast results with limited sample preparation.  The applicable ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • SPME/GC Analyses of Sulfur Gases and VOCs, Using a Carboxen/PDMS Fiber

    Sample extraction of sulfur compounds and VOCs by traditional methods can be difficult and expensive. Typically, sulfur analysis requires concentration of the gas using adsorbent tubes containing carbon adsorbents. Analysis by such means, however, requires the use of an expensive thermal desorption unit to heat the tubes before transferring the gases to a gas chromatograph. Analysis of VOCs ...

  • Influence of surface modification by sulfuric acid on coking coal's adsorption of coking wastewater

    Coking coal, the raw material of a coke plant, was applied to the adsorption of coking wastewater. In this study, coking coal was directly treated with sulfuric acid to improve its surface properties and adsorption ability. Acid treatment was carried out at various concentrations, by varying from 0.001 to 1 mol/L. The samples were characterized by ash content analysis, scanning electron ...

  • Emissions, Concentrations, & Temperature: A Time Series Analysis

    Abstract  We use recent advances in time series econometrics to estimate the relation among emissions of CO2 and CH4, the concentration of these gases, and global surface temperature. These models are estimated and specified to answer two questions; (1) does human activity affect global surface temperature and; (2) does global surface temperature affect the atmospheric concentration of ...

  • Tips for Refinery Gas Analysis

    Refinery gas analysis (RGA) is an important application in oil and gas which characterizes the gases produced during crude oil refining, including stack emission, flame and reformate streams. The challenge in RGA analysis is the reliable analysis of variable sources and compositions of gases produced via fluid catalytic cracking (FCC). The analysis must be quick and accurate to allow engineers to ...

  • Advanced gas analysis - on the go

    The field of ambient air analysis - monitoring industrial and other environments for harmful concentrations of gases - has traditionally faced a technology limitations: Would you prefer a complete and reliable tool, which will be bulky, complicated and inconvenient? Or would you like a nice portable one that's simple and lightweight, but unreliable and limited in its capability? Truly complete ...

  • 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 ...

  • Case study - chroma S Sulfur compounds analysis (H2S and CS2, 0/300ppm) for emission application in a paper mill

    Paper mills use large quantities of sulfur substances in particular in the process of cellulose burning (Kraft cooking). CS2 and H2S emissions are a real problem for the environment (toxicity, odors...). Nowadays, emissions are submitted to regulations (Directive n° 2001/81/EC of European Parliament and Council October 23, 2001) and factories must respect these rules by installing filter or ...

  • Preparation and characterization of sorbents prepared from ash (waste material) for sulfur dioxide (SO2) removal

    Sorbents synthesized from various types of ash (coal fly ash, coal bottom ash, oil palm ash, and incinerator ash) for flue gas desulfurization were investigated. The sorbents were prepared by mixing the ashes with calcium oxide and calcium sulfate using the water hydration method. The effects of various sorbent preparation variables, such as the hydration period, the ratio of calcium oxide to ...
