Silver Sonic

The Silver Sonic process is a World first patented system for the removal of coke impregnated refractory materials from areas such as reactor risers and reactor cyclones in catalyst cracking units. Silver Raven was the first company in the World to successfully completed a Catalyst cracking unit shutdown removing refractory materials from a reactor riser.

The Silver Sonic System utilised Ultra High Pressure Water to remove the refractory materials which can be as much as 180MPa once impregnated with coke. It is suitable for both Hot Wall and Cold Wall applications with or without the inclusion of stainless steel fibre. Production rates are far in excess of traditional methods, where entire portions of the catalyst cracking unit would have had to have been replaced as manual demolition is not practical due to the extended time periods that would be needed, and the safety issues associated with the manual demolition of these types of materials.

Benefits of the Silver Raven system are:

  • Safety - Operated Remotely – No Confined Space Entry.
  • Reduced Cost - Shorter shutdown time compared to jack hammer methods.
  • Eliminates Periodic Manual Inspections - Thanks to on board cameras that monitor and record progress.
  • No Damage - To refractory anchors or steel vessel.
  • Accurate Removal - Coke impregnated refractory removed with no over break.
  • Significantly Reduced Worker Fatigue - No jack hammering required.
  • Reduced Injuries - Due to elimination of jack hammers.
  • Complete Removal - All refractory and coke removed and steel surface prepared to Sa2½ finish.
  • No Dust - Workers not subjected to a carcinogenic atmosphere.
  • Environmentally Friendly - Minimal water usage due to patented technology.
