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 process and apparatus is for recycling LCO and/or HCO to an FCC unit to recover additional distillate. Spent catalyst recycle in the FCC unit may be used to improve distillate yield. A hydroprocessing zone may saturate cycle oil aromatics for cracking in an FCC unit. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone for hydrotreating feed to the FCC unit. Additional recovery of cycle oil for recycle is obtained by heating slurry oil prior to vacuum separation.

Abstract: A process and apparatus is for recycling HCO and/or naphtha from a first FCC unit to a second FCC unit to recover additional distillate and/or light olefins. A first catalyst stream for the first FCC unit may be isolated from a second catalyst stream for the second FCC unit. Fractionation of second cracked products from the second FCC unit may be separate from fractionation of first cracked products from the first FCC unit.

Abstract: A process and apparatus for the dehydrogenation of paraffins is presented. The process utilizes a reactor that includes a slower flow of catalyst through the reactor, with a counter current flow of gas through the catalyst bed. The catalyst is regenerated and distributed over the top of the catalyst bed, and travels through the bed with the aid of reactor internals to limit backmixing of the catalyst.

Abstract: One exemplary embodiment can be a process for removing one or more sulfur compounds from a first liquid. The process can include passing the first liquid through a first inlet and a second liquid through a second inlet of a vessel, passing the first and second liquids through the passageway for facilitating contacting of the first and second liquids to extract the one or more sulfur compounds from the first liquid to the second liquid, and passing the first liquid through the first outlet and the second liquid through the second outlet. Often, the vessel has a plurality of vortex contactors, and a first outlet and a second outlet. The plurality of vortex contactors can include a first vortex contactor, in turn having at least one wall forming a perimeter about an interior region and including a first side and a second side forming a passageway communicating the first liquid from an exterior to the interior region, and a frustum positioned proximate to the passageway and abutting the at least one wall.

Abstract: One embodiment can be an apparatus for contacting a first liquid and a second liquid. The apparatus can include a vessel, which in turn, may include at least one wall, a first member, and a funnical frustum. The at least one wall can form a perimeter about an interior space. Also, the first member can be positioned within the interior space and form a plurality of passageways. Each passageway may be bordered by a first side and a second side from an outer region to an interior surface of the first member. Generally, the funnical frustum is positioned downstream of the first member to facilitate a swirling of at least one of the first and second liquids.

Abstract: A process for recovering catalyst from a fluidized catalytic reactor effluent is disclosed comprising reacting a reactant stream by contact with a stream of fluidized catalyst to provide a vaporous reactor effluent stream comprising catalyst and products. The vaporous reactor effluent stream is contacted with a liquid coolant stream to cool it and transfer the catalyst into the liquid coolant stream. A catalyst lean vaporous reactor effluent stream is separated from a catalyst rich liquid coolant stream. A return catalyst stream is separated from the catalyst rich liquid coolant stream to provide a catalyst lean liquid coolant stream, and the return catalyst stream is transported back to said reacting step.

Abstract: A dehydrogenation process and apparatus contact a paraffinic stream with dehydrogenation catalyst to product olefinic product gases. The olefinic product gases are separated from spent dehydrogenation catalyst and contained in a confined space that has a smaller volume than the reactor particularly at the same elevation. The containment of the olefinic product gases facilitates quenching the olefinic product gases to terminate reaction and improve selectivity to propylene.
