The FCC process relies upon cyclones to physically separate vapor gases from solid catalyst particles. This device relates to the use of acoustic detectors to allow on-line measurement of cyclone performance and assist in unit troubleshooting and monitoring. In a fluid catalytic cracking (FCC) vessel containing a cyclone for separating solids from a solids-gas mixture, the cyclone comprises an outlet and an acoustic sensor attached to the outlet of the cyclone.
