  • Matching Oil in Water Analyses with Regulatory Methods - Case study

    When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment. While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, ...

  • PetroSense hydrocarbon sensors and their applications

    The increasing concern about hydrocarbon contamination of process water and produced water has created an increasing need for in-situ, real time, and accurate low cost instrumentation that can provide rapid detection and easily usable in the field. PetroSense sensors [1,2] represents “best in breed” technology for the detection of total petroleum hydrocarbons (TPH). PetroSense sensors ...

  • Acute toxicity of chemically and mechanically dispersed crude oil on juvenile sea bass (Dicentrarchus labrax): Absence of synergistic effects between oil and dispersants

    The goal of this experiment was to assess the relative acute toxicities of mechanically and chemically dispersed oil (Crude Arabian Light) in controlled conditions. Juvenile sea bass (Dicentrarchus labrax) were exposed to four commercial formulations of dispersants (Corexit EC9500A, Dasic Slickgone NS, Finasol OSR 52, Inipol IP 90), to mechanically dispersed oil and to the corresponding ...

  • The advantages of physico-chemical treatment

    Physico-chemical soil treatment is an effective technique to clean contaminated soils, removing a wide range of both organic and inorganic contaminants. Contaminants adhere to the fine-fraction of the soil, such as organic matter and clay/silt. The principle of the method utilizes the difference in grain-size and density of the materials and separates the different fractions by means of ...

  • Combining HVME and Enhanced Bioremdiation for Gasoline Contamination in Groundwater.

    ABSTRACT A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway ...

  • Oil in Water Analysis Method Match Regulatory Method - Case study

    The analysis of oil in water is a worldwide problem that crosses many industries, analytical methods and regulatory agencies. For those in the petroleum industry, the offshore platform oil and grease limits for produced water can be quite different from the effluent coming out of the refinery. For the expanding hydraulic fracturing industry, oil in water limits are driven by whether the frac or ...

  • Large Volume Splitless Injection Using an Unmodified Split/Splitless Inlet and GC-TOFMS for Pesticides and Brominated Flame Retardants

    Abstract Large volume splitless injection for gas chromatography typically requires a special injection port, for example, a programmable temperature vaporizer (PTV), but an alternative setup using concurrent solvent recondensation–large volume splitless injection (CSR-LVSI) and a split/splitless injection port has been reported. This technique was used here, both with and without ...
