  • Method of phenol tar desalting
    Patent number: 6034282
    Abstract: A method for reduction of salt content in phenol tars with no additional solvent which washes the tars with water alone in a countercurrent flow extractor and substantially reduces the level of salt in the tar.
    Type: Grant
    Filed: July 31, 1998
    Date of Patent: March 7, 2000
    Assignee: General Electric Company
    Inventors: Arkady S. Dyckman, Vladimir I. Sarge, Yelena N. Sarge, Boris I. Gorovits
  • Phenol tar desalting method
    Patent number: 5962751
    Abstract: A tar desalting process wherein the tar containing salts is mixed with dilute aqueous orthophosphoric acid in either a batch or continuous process, allowed to settle into two phases, an organic phase and an aqueous phase containing most of the salts which is then removed from the organic phase. The process removes a high percentage of the salts from the tar and reduces fouling and corrosion of downstream equipment.
    Type: Grant
    Filed: April 26, 1996

    Patent number: 5847235
    Abstract: A method for reduction of salt content in phenol tars with no additional solvent which washes the tars with water alone in a countercurrent flow extractor and substantially reduces the level of salt in the tar.
    Type: Grant
    Filed: June 5, 1997
    Date of Patent: December 8, 1998
    Assignee: General Electric Company

  • Phenol tar processing method
    Patent number: 5672774
    Abstract: Valuable products are recovered from phenol tar by thermocracking under controlled conditions in the presence of polyphosphoric acid. Bisphenol A tars can be optionally cracked under these conditions mixed with the phenol tar and enhanced yields obtained.
    Type: Grant
    Filed: October 24, 1995
    Date of Patent: September 30, 1997
    Assignee: General Electric Company
    Inventors: Arkady S. Dyckman, Vadim P. Boyarsky, Alexander S. Malinovskii, Yurii I. Petrov, Leontii M. Krasnov, Andrey V. Zinenkov, Boris I. Gorovits, Sergey N. Chernukhim, Anatoly D. Sorokin, John W. Fulmer
  • Co-cracking of BPA and phenol process tars
    Patent number: 5504251
    Abstract: This invention relates to processing of a mixture of tars produced in phenol manufacture and in bisphenol manufacture. The heating of a bottom liquid from a bisphenol-A process together with phenol tar from in a cumene-to-phenol process in a distillation column-type thermal cracking reactor at 290.degree.-360.degree. C. at a mass ratio of 1:(1-10) is employed. The process is carried out by feed entering into the middle of the column and valuable products removed as overhead.
    Type: Grant
    Filed: March 9, 1995
    Date of Patent: April 2, 1996
    Assignee: General Electric Company
    Inventors: Arkady S. Dyckman, Andrey V. Zinenkov, Boris I. Gorovits, Valentina Y. Shefter, John W. Fulmer, William D. Kight
  • Phenol tar waste reduction process
    Patent number: 5457244
    Abstract: An improved phenol tar cracking process using a rectification column as a hydrocracker obtains an increased yield of valuable products, phenol, cumene and alpha-methylstyrene, by taking from 50 to 100% of the acetophenone in the reactor overhead with the cracked product stream.
    Type: Grant
    Filed: October 4, 1994
