    Abstract: In an FCC apparatus in which swirl arms are used to discharge gas and catalyst from a riser, the swirling movement of the catalyst particles is inhibited while impeding the catalyst particles and gaseous products from exiting the disengaging chamber and entering a reactor annulus. The catalyst particles and gaseous products pass through a tunnel comprising a vertical wall to enter the reactor annulus. The vertical wall presents a face that is opposed to the angular direction in which the catalyst particles and gaseous products swirl.
    A baffle may be located at the intersection between the reactor annulus and the disengaging chamber to deflect catalyst laterally in a stripping section after exiting the reactor annulus. The baffle may be equipped with openings to fluidize the large proportion of catalyst passing over this region to effectively pre-strip this catalyst before it enters a stripping section.

    Abstract: A method and apparatus for processing hydrocarbons are described. The method includes fractionating a hydrocarbon stream to form at least two fractions. The first fraction is reformed to form a reformate stream, and the reformate stream is introduced into an aromatics processing zone to produce aromatic products. At least a portion of the second fraction is cracked in a fluid catalytic cracking unit. A selectively hydrogenated light naphtha stream is formed by separating the cracked hydrocarbon stream into at least two streams and selectively hydrogenating the light naphtha stream, or selectively hydrogenating the cracked hydrocarbon stream and separating the hydrogenated cracked hydrocarbon stream into at least two streams. Aromatics are extracted from the selectively hydrogenated light naphtha stream forming an extract stream and a raffinate stream. The extract stream is hydrotreated, sent to the aromatics processing zone to produce additional aromatic products.

    Abstract: In an apparatus for fluid catalytic cracking a riser having a top and a bottom for fluidizing and cracking a hydrocarbon feed stream by contact with catalyst exits an outlet at the top of the riser. A downer in communication with the outlet of the riser receives cracked hydrocarbon product and catalyst. A swirl duct in communication with the downer has a discharge opening below the outlet for discharging said cracked hydrocarbon product and catalyst. A stream of hydrocarbon feed and a catalyst is passed upwardly in a riser. A stream of gaseous hydrocarbon products and catalyst is directedly downwardly and then the stream of gaseous hydrocarbon products and catalyst are directed to flow in an angular direction to separate gaseous hydrocarbon products from the catalyst.
