  • OIL IN WATER ANALYZER
    Publication number: 20140036255
    Abstract: An oil in water analyzer for measuring the concentration of hydrocarbons in an effluent stream. The oil in water analyzer has a valve system for acquiring a sample from an effluent stream. An extraction device is used for mixing a known volume of a solvent and the sample to produce a hydrocarbon/solvent mixture. A second valve is used for transporting the hydrocarbon/solvent mixture to a spectroscopic cell. It is at the spectroscopic cell where the concentration of hydrocarbons in the hydrocarbon/solvent mixture is evaluated.
    Type: Application
    Filed: October 11, 2013
    Publication date: February 6, 2014
    Applicant: Phillips 66 Company
