Abstract
Modern processes and arrangements for FCC processes can be obtained using a stacked FCC reactor-regenerator arrangement. These processes and arrangements use a stacked FCC unit having a bottom regeneration vessel, a superadjacent reactor vessel, and a stripping vessel laterally offset from and in open communication with the reactor vessel to make a two-stage regenerator having a lower first stage regeneration, an upper second stage of regeneration, and a catalyst cooler for removing feed from the catalyst. The process and arrangement makes complete use of the three existing vessels in the stacked reactor-regenerator arrangement by changing the function of the upper reactor vessel and the stripping vessel and adding a reactor vessel to the side of the stacked FCC arrangement. Therefore, apart from the addition of the new reactor only relatively minor modifications are necessary to more fully utilize stacked FCC reactor-regenerator arrangements.
