  • Oil in water analyzer
    Patent number: 8817241
    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: Grant
    Filed: October 11, 2013
    Date of Patent: August 26, 2014
    Assignee: Phillips 66 Company
    Inventors: Christopher J. LaFrancois, James F. Stewart, Gregory C. Allred, Marion Ash

  • Method of inhibiting in situ silicate formation in desulfurization sorbents
    Patent number: 7951740
    Abstract: A method for regenerating desulfurization sorbents that minimizes the in situ formation of one or more silicates. It has been discovered that regenerating sulfur-laden sorbent particles in a carbon oxide-rich environment unexpectedly reduces the in situ silicate formation rate, as compared to similar sorbents regenerated using conventional methods.
