  • Moisture in Oils: The Three-Headed Beast

    Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination.  Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved.  All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as ...

  • Advances in Optical Techniques for Moisture and Hydrocarbon Detection

    Abstract Every year, the world uses in the region of 100 trillion scf (standard cubic feet) of natural gas (1). All of this gas requires treatment before it enters the pipeline, making natural gas processing a key global industry. Minimization of costs is achieved through optimization of these processes, requiring accurate online measurement of gas composition at multiple points in the ...


  • Heat and Moisture Transfer Characteristics of Compacted Mackenzie Silt

    The heat and moisture transfer characteristics of a silt from the Mackenzie River Valley have been determined in a laboratory investigation. A dual gamma-ray scanner was used to measure the changes in density and volumetric moisture content along the soil samples. The coefficients of soil-water diffusivity under isothermal conditions and under temperature gradients have been obtained. The ...

  • Continuous monitoring of moisture present inside a process chamber

    Problem Statement Moisture inside a process chamber is a big silent killer during wafer production. When production yield goes down, it is hard to pinpoint the source of the problem. Most of the time wafers need to be sent to labs for analysis, while production is stopped. If the problem is related to a high level of moisture inside the reactor, there are several factors that can cause ...

  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

  • Monitoring the performance of moisture purifiers for process gases

    Problem Statement Moisture purifiers are a big aid in keeping moisture levels under control inside a process chamber. They are provided by manufacturers with certain life expectancies, which vary depending on the moisture content of the gas being purified. As a result, it is difficult to determine which gases have a high moisture content and which moisture purifier is becoming ...

  • Influence of initial moisture on pyrolysis of fresh biomass

    Experiments were performed in a thermogravimetric analyser to understand the effects of initial moisture of biomass on its pyrolysis and kinetics. Scanning electron microscopy, X-ray diffractometry and Fourier transform infrared spectroscopy were employed to determine the effects of the initial moisture of grass on the char structure. Kinetic parameters were obtained by applying Flynn-Wall-Ozawa ...

  • Suction-Moisture Content Calibration of Filter Papers from Different Boxes

    The filter paper method is probably the simplest of the methods available for estimating the suction of a clay soil. The method measures soil suction indirectly by simply measuring the moisture content of a filter paper having been brought to the same suction as the soil. Calibration of representative specimens of the filter paper over a range of known suctions defines the suction-moisture ...

  • Coupled Heat and Moisture Flow in Unsaturated Swelling Clay Barriers

    The main thermodynamic forces active in the near field of a nuclear fuel waste multiple barrier system during the unsaturated stage are the gradients of temperature, fluid pressure, and chemical potentials. The processes that have a direct impact on the transport mechanism of heat and moisture within the clay-based compacted buffer material are coupled. The major problems in describing coupled ...

  • MCM’s heated Silicon Sensor Moisture Analyser against Aluminium Oxide and Oscillating Crystal Moisture Analysers, during Molecular Sieve Test Runs at St Fergus, Scotland

    Abstract Methods for dehydrating natural gas using molecular sieves (mol sieve) are well established. Many strategies have been developed with the intention of extending mol sieve lifetime and preventing unplanned shut-downs of dehydration units. The amount of adsorbent required in such dehydration processes is determined by the water content in the feed, the end-of-run (EOR) water ...
