1. An apparatus for processing streams from a fluid catalytic cracking unit comprising:

  • a fluid catalytic cracking reactor for contacting cracking catalyst with a hydrocarbon feed stream to crack the hydrocarbons to gaseous product hydrocarbons having lower molecular weight and deposit coke on the catalyst to provide coked catalyst;

    a product outlet for discharging said gaseous product hydrocarbons from said reactor;

    a regenerator for combusting coke from said coked catalyst by contact with oxygen;

    a flue gas outlet for discharging flue gas from said regenerator;

    a product recovery section in downstream communication with said product outlet, said product recovery section for separating said gaseous products into a plurality of product streams including a selected product stream; and

    said regenerator being in downstream communication with said product recovery section.
