  • 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. ...

  • Case Study - Source Area Remediation of PCE in Soil - Fair Lawn, New Jersey

    TRS Group, Inc. (TRS) was retained by Anderson Mulholland and Associates, Inc. (AMAI) to perform an Electrical Resistance Heating (ERH) remediation of DNAPL in soil at the former Topps Dry Cleaners property in Fair Lawn, NJ. The remedial goal of this project was a reduction of tetrachloroethene (PCE) in soil to less than 1 milligram per kilogram (mg/kg) in every soil sample. Final confirmatory ...

  • 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 ...

  • 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. ...

  • Analysis of DNAPL source depletion costs at 36 Field Sites

    Abstract A recent U.S. Environmental Protection Agency expert panel on dense non-aqueous phase liquid (DNAPL) remediation concluded that uncertainty in the costs and benefits of applying source depletion technologies (i.e., active remediation in source zones) is one key factor that discourages widespread use of these technologies at DNAPL sites (Kavanaugh et al., 2003). To reduce this ...

  • 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, ...

  • Reviewed - Top 5 Thermal Soil Remediation Companies

    Soil remediation broadly refers to the ‘repair’ and ‘renewal’ of contaminated land. To preserve the sanitation of the area, contaminants in the land are treated or removed using different soil remediation techniques. However, one of the most effective techniques that have greatly evolved over the years to restore the damaged soil is the thermal soil remediation technique. ...

  • Ceramic membranes with higher abrasion resistance

    High flux rates, combined with a very high chemical and thermal resistance and the resulting operational reliability - these are the reasons why users worldwide opt for ceramic membranes. Up to now, the only parameter where ceramic membranes performed well but not excellent was abrasion resistance. Therefore, filtering of abrasive matter required pre-treatment stages such as prefiltration, ...

  • Thermal treatment of thick peat layers – DNAPL removal and shrinkage

    Abstract A PCE DNAPL source zone was treated using thermal conduction heating combined with multi-phase extraction. Thick peat layers, even when contaminated with PCE DNAPL, were remediated to average soil PCE concentrations of 0.17 mg/kg (99.6% reduction compared to starting levels). This was accomplished in 83 days of heating, by elevating the temperature to the boiling point of water, and ...
