  • Optimization of caustic usage
    Patent number: 6667178
    Abstract: A method for determining the quantity of phenol extracted into an aqueous solution of an alkali metal hydroxide uses a measurement of the pH of the solution, from which the equivalents of phenol relative to alkali metal hydroxide in solution is determined. A method for optimizing the use of an aqueous solution of an alkali metal hydroxide in a phenol recovery process uses pH measured to regulate the feed rate of the aqueous solution.
    Type: Grant
    Filed: May 7, 2001
    Date of Patent: December 23, 2003
    Assignee: Sunoco, Inc. (R&M)
    Inventor: Robert W. Emblidge
  • Method for recovery of phenol from aqueous streams
    Patent number: 6620980
    Abstract: An improved method for the recovery of phenol from aqueous streams comprises adding a relatively non-polar solvent to a phenol containing aqueous stream to improve the separation of the phenol form the aqueous stream. The improvement results in a phenol stream with a reduced level of salt carried over from the aqueous stream.
