  • SITRANS SL in-situ analyzer saves cost for a steel plant replacing existing extractive setup – Case Study

    The customer Steel industry plants all over the world have multiple processes, most of them emitting CO and CO2 in very high concentrations (tens of %). CO is used as a combustible due to its high calorific value. It is stored in a huge tank before it is used by the power plant next door. CO in such high concentration is explosive in presence of a few molecules of oxygen. Therefore, ...

  • C18 extraction of atrazine for increased sensitivity in the RaPID Assay

    Performance of an increased sensitivity method utilizing an extraction and concentration step to increase analyte concentration of the assayed sample is presented. Recently, Shepard and Carr (1992) reported a method for increased detection of atrazine by gas chromatography using C18 solid-phase extraction (SPE) with a 10 mL water sample. An application with BakerbondÒ C18 SPE columns for ...

  • Optimization of a microwave-assisted extraction procedure for the determination of selected alkyl, aryl, and halogenated phenols in sewage sludge and biosolids

    A microwave-assisted extraction method for the determination of 15 alkyl, aryl, and halogenated phenols in sewage sludge and biosolids samples was developed and optimized. The effects of solvent, temperature, time, moisture content, acid, and number of extractions on the recovery of phenols were evaluated. Results indicated that extraction solvent had the greatest impact on the recovery of all ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Low-mass PM analyzer MEXA-1370PM — Improvement of the Performance for PM Composition Analysis —

    Particulate matter (PM) emitted from engines is currently measured by the filter weight method. The filter weight method passes diluted emission gases through a filter collecting the PM, and post test weighs the mass of the collected PM on a precision balance. However, this method is time consuming, and with decreasing PM emission volumes, improvements in accuracy were needed. So the MEXA-1370PM ...

  • Process analytics throughout the entire natural gas pipeline supply chain – Case Study

    Natural Gas (NG) Natural Gas is a vital component of the world's supply of energy. It is one of the cleanest, safest, and most useful of all energy sources. Unlike other fossil fuels, natural gas is clean burning and emits lower levels of potentially harmful by products into the air. While natural gas is formed primarily of methane, it can also include smaller amounts of higher ...

  • Plastic Housewraps (Air Barriers) a Life Cycle Analysis of Their Environmental Benefits

    The use of air barriers in the construction of residential housing in North America has increased markedly during the last decade. The most commonly used air barriers have been particular plastic materials applied to the exterior of a home behind the finishing of brick or siding. The paper analyses, using life cycle techniques, the conservation of energy resulting from the use of these barriers ...

  • Development of a highly sensitive assay for enzyme‐mediated reductive degradation of polychlorinated dibenzo‐p‐dioxin

    The degradation of 2‐chloro‐4,5‐O‐(4′‐methyl‐7′, 8′‐diphenyl)ether (CMDPE), an analog of 2,7‐dichlorodibenzo‐p‐dioxin (2,7‐DCDD), mediated by Geobacillus sp. UZO 3 cell‐free extract was monitored. Ethyl acetate extracts of a complete reaction mixture incubated at 65°C for 18 h were analyzed either by thin layer chromatography (TLC) fractionation coupled with spectrometric detection or by gas ...

  • Methyl Isobutyl Ketone (MIBK) Market - Global Industry Analysis, Size, Share, Growth, Trends And Forecast, 2012 - 2018

    Methyl isobutyl ketone (MIBK) is a colorless organic compound naturally occurring in grapes, orange, and vinegar. MIBK can dissolve in water, alcohol, ether and benzene. There are two main methods of producing MIBK. One is through acetone condensation, which gives diacetone alcohol that dehydrates to give mesityl oxide, which is then hydrogenated to MIBK. MIBK is also produced from isopropanol, ...
