Distribution Study Reactor & Cyclones
-
Flow distribution analysis of individual cyclone performance to determine
dip leg blockage cyclone blockage or maldistribution
- Results enable customers to optimize maintenance strategy of cyclones
Since FCCU’s have been modified to achieve the cracking reaction
in the Riser instead of the Reactor, the Reactor’s present-day role
is to minimize post Riser reactions by providing efficient catalyst/hydrocarbon
disengagement. A TRACERCO Diagnostics™ Distribution study is used
to determine relative amounts of vapor or catalyst traffic entering the
primary Reactor cyclones.
 External
detectors are placed around the Reactor vessel at the locations of the
primary cyclone inlets and secondary gas outlets. For a normal cyclone
system, each of the primary cyclones should receive the same amount of
vapor and catalyst traffic, so all the detectors should receive the same
amount of tracer radiation following injection into the Riser. Significant
differences in radiation readings between the detectors indicates cyclone
maldistribution.
