FCC EXPANDER

SOUTH KOREA

FCC EXPANDER

The FCC Expander operators were
experiencing severe vibration due to catalyst
fines sticking on the rotating blades resulting
in a shutdown every six weeks, on average.

After Therma-Chem Treatment

Figure 1 shows the daily average vibration
level of the four vibration probes on the
expander for the prior year before using
Therma-Chem. Treatment with Turbo-Mor
commenced in October 2013 and Figure 2
reflects the first year of treatment. There were
no high vibration trips for the next 30 months
of operation. This presented a significant
saving for the plant.
