  • 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.

  • DEHYDROGENATION AND PYROLYSIS PRODUCT RECOVERY WITH A COMMON DEMETHANIZER
    Publication number: 20240166581
    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.
