  • Patent number: 6080302
    Abstract: A method for producing a process oil is provided in which an aromatic extract oil is added to a paraffinic rich feed to provide a blended feed. The blended feed is then extracted with an aromatic extraction solvent to yield a raffinate which subsequently is hydrotreated to provide a process oil.
    Type: Grant
    Filed: December 15, 1998
    Date of Patent: June 27, 2000
    Assignee: Exxon Research and Engineering Co.
    Inventors: Keith K. Aldous, Jacob Ben Angelo, Joseph Philip Boyle
  • Patent number: 6024864
    Abstract: A method for producing a process oil is provided in which an aromatic extract oil is added to a paraffinic rich feed to provide a blended feed. The blended feed is then hydrotreated in a first hydrotreating stage to convert at least a portion of sulfur and nitrogen in the feed to hydrogen sulfide and ammonia. After stripping, the feed is subjected to a second hydrotreating stage to provide a process oil.
    Type: Grant
    Filed: December 17, 1998
    Date of Patent: February 15, 2000
    Assignee: Exxon Research and Engineering Co
    Inventors: Keith Kaluna Aldous, Jacob Ben Angelo, Joseph Philip Boyle, Bruce M. Jarnot, Wayne E. Hanson
  • Patent number: 5853569
    Abstract: A method for producing a process oil is provided in which a napthenic rich feed is enriched with an aromatic extract oil. The enriched feed is then subjected to a solvent extraction thereby providing a process oil.
    Type: Grant
    Filed: December 10, 1997
    Date of Patent: December 29, 1998
    Assignee: Exxon Research and Engineering Company

  • Patent number: 5846405
    Abstract: A method for producing a process oil is provided in which an aromatic extract oil is added to a napthenic rich feed. The combined feed is then hydrotreated in a first hydrotreating stage to convert at least a portion of sulfur and nitrogen in the feed to hydrogen sulfide and ammonia. After stripping the feed is subjected to a second hydrotreating stage to provide a process oil.
