Description:
A traditional FCC unit designed to produce 3% propylene would recycle about 15% of the net stabilized naphtha to the primary absorber. In systems with propylene yields approaching 22 wt%, most of the naphtha is cracked to LPG resulting in a dramatic shift in the operation of the primary absorber, with nearly 200% recycle of the stabilized naphtha product required to maintain high propylene recovery. UOP has completed a set of process designs to compare the economics of different olefin recovery units and determined that an optimally designed olefin recovery system should take advantage of synergies between ethylene, propylene and naphtha recoveries for the lowest possible cash cost of production, even when propylene yields are greater than 20 wt%.. In this paper UOP will present operating and capital cost comparisons along with discussion of the flowsheet optimization choices that can be made based on the refiners needs.
