  • Distributed Measurements Unlock the Future of Design

    The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...

  • E-Guide Measuring Oil Viscosity

    The most important physical property of a lubricating oil is viscosity. Viscosity determines the load carrying ability of the oil as well as how easily it circulates. The correct balance between high viscosity for load carrying and low viscosity for ease of circulation must be considered for any lubricant and its application. ...

  • A simple numerical method for snowmelt simulation based on the equation of heat energy

    This paper presents one-dimensional numerical model for snowmelt/accumulation simulations, based on the equation of heat energy. It is assumed that the snow column is homogeneous at the current time step; however, its characteristics such as snow density and thermal conductivity are treated as functions of time. The equation of heat energy for snow column is solved using the implicit finite ...

  • Reliable silica monitoring supports power station efficiency

    West Burton B CCGT is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million UK homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Sean Todd, the Plant’s Control ...

  • New Developments in Thermal Dispersion Mass Flow Meters: In-The-Field Compensation for Changes in Natural Gas Composition

    Introduction The flow of natural gas in pipelines is often complicated by changes in the composition of the gas. The method described in this paper solves the problem of variable composition via a new four-temperature mass flow sensor. The new (low sensor feeds its measurements into the algorithms of an advanced mathematical model that includes gas properties in its calculations. The method ...

  • Martinsburg Plant, Washington D.C. – Massive upgrade and expansion case study

    The Martinsburg plant is unusual in a number of ways. Located on the outskirts of Martinsburg the plant has a strong relationship with the local community. When other facilities were closing their doors or postponing expansion projects, the Martinsburg cement plant invested over US$500 million in a massive upgrade and expansion that brought capacity up to 1.8 million t of cement. Although cement ...

  • Enhanced Removal of Separate Phase Viscous Fuel by Electrical Resistance Heating and multi phase Extraction

    Abstract A floating hydrocarbon plume at a manufacturing facility in Georgia was remediated using electrical resistance heating (ERH) and multi-phase extraction. The hydrocarbon was a specialty fuel similar to kerosene or diesel fuel. Initially, hydrocarbon covered an area of 4900 ft2 (500 m2) and was up to l0 ft (3 m) thick, with most wells containing 1-3 ft (0.5-1 m) of hydrocarbon. ...

  • China Case Study (In Situ Gas Thermal Remediation (GTR™))

    Gas Thermal Remediation (GTR™) was recently used to successfully remediate benzene and chlorobenzene impacts in China. This was the first time in situ thermal remediation was used in the history of Chinese remediation efforts. In partnership with JSDDBS, GEO used its Thermal Conductive Heating (TCH) to remove contaminants from soil and groundwater at 100 degrees Celsius. The final ...

  • Thermal Remediation of Karst Limestone – Redstone Arsenal, Alabama

    Abstract: Electrical resistance heating (ERH) was used for the thermal remediation of two sites at Redstone Arsenal (RSA) near Huntsville, Alabama. Both sites feature karst limestone with heavy clay overburden. The two sites are located about five miles (10 km) apart, but differ considerably in the characteristics of the limestone. At site RSA-053, the heavy clay is underlain by very hard, ...
