  • Dehydrogenation and pyrolysis product recovery with a common refrigerant
    Patent number: 12643843
    Abstract: A process and apparatus cool a pyrolyzed stream and a dehydrogenated stream in respective cold boxes by use of a refrigerant compressed with a common compressor. The refrigerant is compressed and used to cool a pyrolysis cold box and a dehydrogenation cold box.
    Type: Grant
    Filed: November 15, 2023
    Date of Patent: June 2, 2026
    Assignee: UOP LLC

  • Dehydrogenation and pyrolysis product recovery with a common demethanizer
    Patent number: 12643842
    Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A stripping column for fractionating a dehydrogenation stream is coupled with a demethanizer column for fractionating a pyrolyzed stream. The stripping overhead stream comprising C2? hydrocarbons are fractionated with the pyrolyzed stream in the demethanizer column. The coupling omits the need for a conventional deethanizer column and separate refrigeration system in the propane dehydrogenation unit.

  • DEHYDROGENATION AND PYROLYSIS PRODUCT RECOVERY WITH A COMMON DEPROPANIZER
    Publication number: 20240165534
    Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A common depropanizer fractionates propane feed and pyrolysis reactor effluent to provide a C3 stream. A dividing wall may be used in the column to prevent cross contamination by the pyrolysis effluent with the propane dehydrogenation feed.

  • DEHYDROGENATION AND PYROLYSIS PRODUCT RECOVERY WITH A COMMON C3 SPLITTER
    Publication number: 20240166580
    Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A common C3 splitter column fractionates propylene product from propane recycle to a paraffin dehydrogenation reactor. The C3 hydrocarbons may be provided from a pyrolysis reactor and from a dehydrogenation reactor.
