Effective distribution of edible oils
Edible oil was injected at five sites to promote reductive dechlorination. The edible oil was injected as a non-aqueous phase liquid (NAPL) or as an emulsion of oil, an emulsifier, and water. At Dover Air Force Base, injection of the emulsion into a barrier resulted in greater distribution of the total organic carbon (TOC) and more rapid dechlorination than direct injection of the edible oil into ...

PETROTOX: An aquatic toxicity model for petroleum substances
A spreadsheet model (PETROTOX) is described that predicts the aquatic toxicity of complex petroleum substances from petroleum substance composition. Substance composition is characterized by specifying mass fractions in constituent hydrocarbon blocks (HBs), based on available analytical information. The HBs are defined by their mass fractions within a defined carbon number range or boiling ...

Emulsion breakingtechniques for oil in water solvent extractions
Certain types of samples, such as those containing detergent, may form emulsions when doing an oil in water extraction into a solvent. The boundary between the solvent and the sample will have an emulsion layer that lias a cloudy or milky appearance as shown in tlris photo. According to U.S. EPA Method 1664, "if the emulsion is greater than one-third the volume of the solvent layer. Hie ...

Emulsion-Breaking Techniques for Accurate Oil in Water Measurements
A White Paper discusses emulsion-breaking techniques for ensuring accurate oil in water measurements. Certain water samples, such as those containing detergent, may form an emulsion when oil in water extraction into a solvent is done. In order to ensure an accurate measurement, the emulsion must be broken. Six techniques are described that can be used for reducing an emulsion in order to obtain ...

Moisture in Oils: The Three-Headed Beast
Abstract Moisture contamination in in-service lube oils is perhaps one of the most destructive forms of engine corrosion second only to particle contamination. Water contamination in oil can be categorized into three forms of water; Free, emulsified, and dissolved. All forms of water have direct consequences to the oil and gears of the engine, but indirect consequences as well. Direct ...
