Three trends in FCC development include new stripper design, improved feed distribution and more highly contained reactor riser termination systems. An accumulation of commercial operating data indicate the combined benefits from these technologies are a result of robust mechanical design features developed in conjunction with successive process improvements. As a result, FCC designers are reporting run lengths in excess of 60 months, while reducing feed outages and planned turnarounds. Of course there are many other important considerations within the context of the total unit, from the FCC`s reactor/regenerator to the main fractionator and gas plant. For example, to improve reliability and reduce maintenance, at least one FCC licensor favors planning a new FCC unit such that the layout of the reactor and regenerator vessels, and the relative vessel elevations, are arranged to eliminate expansion joints in both the regenerated and spent catalyst circuits. Process and operations engineers would benefit by remaining aware of the phalanx of unit-side process and operations issues and {open_quotes}micro-focusing{close_quotes} on some of the latest developments in feed injector and reactor stripper design, as well as reduction of post-riser cracking.
