  • The Seven Deadly Sins of Process Analyzer Applications

    Abstract On-line process gas analyzers comprise a relatively small proportion of the capital investment in a grass roots project but they require detailed attention if they are to be successfully implemented and fully exploited. The chain is long and the mistakes are many. It runs from front end engineering design, to EPC detailed design, through systems integration, selection of technique ...

  • Carbon dioxide gas case study

    Application Moisture] is measured in carbon dioxide gas pipelines and processing plants. Problem The presence of moisture in carbon dioxide gas promotes corrosion. Perhaps more significant is the fact that moisture will readily form ice when pressure is reduced. The ice can readily freeze up pressure regulators, valves, and orifice plates causing a loss of flow and even ice ...

  • Case study - N°NG1 – Natural gas monitoring – Medor Exp

    Context & Challenges Natural gas used for household consumption typically contains odorant sulfur components for safety reasons. As natural gas is normally odorless, the sulfur components are artificially added. When natural gas is transported between various companies, regions or countries, gas companies have to verify that the sulfur species are present as specified. ...

  • Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas

    Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the ...

  • Field verification of on-line hydrocarbon dew point measurements

    Introduction The Michell Condumax II applies a fundamental measurement principle for direct measurement of hydrocarbon dew point. Measurement performance is assured through comprehensive factory test and calibration, to verify that each analyzer offers accurate determination of the temperature at which hydrocarbon condensate forms. Further extensive examination confirms highly sensitive ...


  • Investigation of the effects of temperature and sludge characteristics on odors and VOC emissions during the drying process of sewage sludge

    Sludge drying is a necessary step for sludge disposal. In this study, sludge was collected from two wastewater treatment plants, and dried at different temperatures in the laboratory. The emission of odor and total volatile organic compounds (TVOCs) during the sludge drying process were determined by an online odor monitoring system. The volatile organic compounds (VOCs) in off-gas were analyzed ...

  • Argon and Nitrogen in Glove Boxes and Blanketed Chambers case study

    Application Moisture is measured in argon or nitrogen when it is used as a blanketing gas in glove boxes and other blanketed applications. Problem The presence of moisture in the blanket gas for a glove box causes serious contamination problems especially when welding or conducting moisture-sensitive chemical reactions. Moisture causes product contamination, ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...

  • Determination of micro and macro elements in waters with the ELAN DRC-e

    The ability of reaction cell technology to reduce the effects of spectral interferences is well-known, but another, lesser-known capability also exists: extending the dynamic range. This is accomplished by adjusting the bandpass parameters with no gas in the cell. Because the bandpass parameters can be adjusted on a per-mass basis, sensitivity can be reduced on selected isotopes without affecting ...
