  • Cracking furnace control
    Patent number: 4747912
    Abstract: For parallel heat exchangers, one using a more preferred heat exchange medium as a heat exchange source and another using a less preferred heat exchange medium, maximum use of the more preferred heat exchange medium is used prior to use of the less preferred heat exchange medium in achieving a desired total heat exchange through the parallel heat exchange system. In employing such a heat exchange system in a cracking process it is combined with individual control of flows of feed fluid and diluent fluid to a plurality of individual cracking tubes in a cracking furnace to maintain a desired mass flow of feed fluid and ratio of mass diluent fluid to steam fluid to each such cracking tube.
    Type: Grant
    Filed: August 24, 1987
    Date of Patent: May 31, 1988
    Assignee: Phillips Petroleum Company
    Inventors: Gary L. Funk, William S. Stewart, Guy S. Pennington, Jr.
