FCC reactor product-catalyst separation: Ten years of commercial experience with closed cyclones

  title={FCC reactor product-catalyst separation: Ten years of commercial experience with closed cyclones},
  author={R. Miller and T. Johnson and C. Santner and A. Avidan and D. Johnson},
FCC reactor closed cyclones were first commercialized ten years ago and have now been installed in over 22 FCC units worldwide. Cumulative commercial experience has shown significant yield benefits, in some cases higher than first estimated, and excellent reliability. By nearly eliminating post-riser cracking, they reduce dry gas make and produce higher yields of desirable liquid products. Trouble-free operation with closed cyclones is attributed to proper design, instrumentation, and operating… Expand
FCC riser quick separation system: a review
The riser reactor is the key unit in the fluid catalytic cracking (FCC) process. As the FCC feedstocks become heavier, the product mixture of oil, gas and catalysts must be separated immediately atExpand
Fluid catalytic cracking
Fluid catalytic cracking, or FCC, was the first application of fine-powder fluidization. Interestingly, the first commercial FCC unit (Esso’s Model I in 1942) had both the reactor and regenerator inExpand
FCC Catalyst Coolers Open Window to Increased Propylene (KBR Paper Number: 2263)
The market demand for propylene has brought a strong emphasis onto many FCC units to run in maximum propylene mode. Increasing reactor temperatures in pursuit of higher propylene, without regeneratorExpand
The Study of Performance in a Novel Gas–Solid Separator
Abstract The three slit-type separator is a new separator which can shorten the residence time of oil & gas and improve the separation efficiency. In this study, a critical validation was carried outExpand
