not severely impair the yield pattern due to a robust feed injector
design, this was confirmed as being the root cause of the
catalyst particles fracture episode.
In this way, a double benefit solution was achieved: the
steam-to-nozzles amount was optimized with the corresponding
savings, and a more evenly distributed steam injection resulted
in a smoother mixing without damaging the quality of
the catalyst circulating inventory. The improved circulation
with reduced particulate losses delivered savings estimated
at $1.3 MM/yr. The three-party cooperation delivered value
by means of significant cost savings and much improved unit
performance at Atyrau's FCCU and is expected to continue to
provide benefits in the future.

agement, tailored FCC catalyst technology and the advanced
hardware technology-enabled AOR to extract the maximum
profitability from the very challenging operation at its RFCCU.
Thanks to the close partnership between different parties,
including the unit licensor and the catalyst supplier, it has
been demonstrated that multidisciplinary teams can achieve
excellent results and drive value for the refinery. The combination
of the RFCCUa
with the proprietary catalysth
delivered
best-in-class bottoms cracking functionality, while preserving
superior metals tolerance, which is crucial to keep the maximum
number of residual streams in the feedstock diet.
