  • Apparatus for Feed Preheating with Flue Gas Cooler
    Publication number: 20100239475
    Abstract: Hydrocarbon feed to a catalytic reactor can be heat exchanged with flue gas from a catalyst regenerator. This innovation enables recovery of more energy from flue gas thus resulting in a lower flue gas discharge temperature. As a result, other hot hydrocarbon streams conventionally used to preheat hydrocarbon feed can now be used to generate more high pressure steam.
    Type: Application
    Filed: March 20, 2009
    Publication date: September 23, 2010
    Inventors: Yunbo Liu, Xin X. Zhu, Daniel N. Myers, Patrick D. Walker
