  • Natural Gas: Complete Analytical Solution

    Chromatotec® has developed in its Research & Development laboratories, a new instrument for hydrocarbon (C1-C6+) measurements and calorific values as well as WOBBE index computation. This analyzer is based on chromatography principle using a Thermal Conductivity Detector (TCD). The sample will be separated into the column and quantified by the detector. A difference of thermal ...

  • The Thermal Probe—Measurement of the Thermal Conductivity and Drying Rate of Soil in the Field

    The thermal probe is a metal rod with an internal heating element and temperature sensor. In the field it is pushed into a predrilled hole in otherwise undisturbed soil, and the thermal properties of the soil are estimated from the temperatures recorded at intervals after a constant power is supplied to the heating element. The following are discussed in this paper: the theory behind the methods ...

  • The Behavior at the Shrinkage Limit of Clay Undergoing Drying

    In this paper, possible links between the shrinkage limit and distinct changes in other properties of a clay soil undergoing drying are discussed. These properties include the volumetric air content of the soil, the heat of wetting, the tensile strength, the total suction, and the thermal resistivity of the soil. The distinct changes are of interest in themselves, and possible explanations for ...

  • A Model Study of the Influence of Stress on the Thermal Conductivity of Dry Sand

    An equivalent resistor model was investigated to determine its suitability for describing the thermal conductivity of dry granular soils. The suitability of the model for incorporating the influence of stress on thermal conductivity was also examined. The parameters necessary to specify the model were determined experimentally by fitting the model to measured values of thermal conductivity from ...
