Abstract: The present disclosure is directed to an apparatus and a compact riser separation system for separating a gaseous mixture from a stream of particles entering from a central riser reactor used for cracking a hydrocarbon feed with the stream of particles. The apparatus provides improved gas solid separation efficiency and maximize containment of the hydrocarbon and minimize residence time in the separation system and thereby minimizing undesired post riser cracking reactions.

Abstract: A packing system includes a first packing element layer including a plurality of blades and a second packing element layer including a plurality of blades. The packing system includes intra-layer variation and/or inter-layer variation. Intra-layer variation includes (i) varying spacing between blades within the first and/or the second packing element layer, (ii) varying sizes of the blades within the first and/or the second packing element layer, and/or (iii) varying angle of inclination of the blades within the first and/or second packing element layer. Inter-layer variation includes the blades of the first packing layer having a first spacing, a first size and a first angle of inclination, and the blades of the second packing layer having a second spacing, a second size, and a second angle of inclination. The second spacing, size, and/or angle of inclination is different from the first spacing, size, and/or angle of inclination.

Abstract: A method and system for increasing olefin production and quality from a hydrocarbon feed comprising a fully integrated multi-stage catalyst regeneration zones with multi-stage reaction zones in series and/or parallel. The multi-stage regeneration with at least one partial and one full burn zone provides an independent control to achieve the lowest possible regenerated catalyst temperature, resulting in highest possible catalyst to oil ratio required to maximize olefins yields through increased catalytic cracking in a multi stage FCC riser/risers.

Abstract: A packing system is disclosed that has a series of flat blades arranged to promote mixing in a fluidized bed such as one in a FCC stripper, with an upward flowing gas stream and a downward flowing solid particle stream. The blade arrangement provides for different gas solids flow directions within a single layer of packing system to enhance cross mixing of gas and catalyst in all directions and reduces the potential for gas and catalyst bypassing. The blade arrangement has splits which minimizes the tendency for phase separation around the blade. The arrangement and sizing of the blades is intended to promote intimate contact between the two phases to ensure efficient mass transfer of material trapped inside the particles to the gas phase. The arrangement of the blades prevents excessive bubble growth and channeling, both of which reduce surface area for mass transfer.
