  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...

  • Electrical Resistance Heating: a Hot New Approach to Soil and Groundwater Remediation

    Electrical Resistance Heating (ERH) is an aggressive remediation technology that can quickly reduce the mass of volatile organic compounds (VOCs) in soil and groundwater by over 99%. The process is often used to clean sites where other technologies have had limited success. Larger ERH sites are cleaned within 6 to 12 months and smaller sites can be cleaned in half that time or ...

  • 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. ...

  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Heat-enhanced bioremediation and destruction - Case Study

    Introduction In situ thermal treatment through Electrical Resistance Heating (ERH) is a proven robust technology for the treatment of volatile organic compound (VOC) source zones. ERH effectively treats the subsurface by volatilizing dense non-aqueous phase liquid (DNAPL) and VOCs, recovering the vapor, and treating the vapor by conventional technologies such as granular activated carbon ...

  • The design of static mixer heat transfer equipment for adhesives, sealants, resins and polymers.

    The fluids handled within the adhesives and sealant industries are amongst the most difficult to handle of any in the main process industries globally. The characteristics which make them particularly difficult to handle include: High viscosities (typically 1-2000 Pa.s, or 1000 to 2 million cP). Often non-Newtonian (viscosity is not constant and varies with shear rate). Some ...
