Third Stage Separators

Emtrol has supplied more tertiary cyclone systems for FCC units than any other cyclone supplier, and our experience in this area is unequaled.  Many of these installations have been operating for more than 20 years and, at this juncture, we have secured over 700 contracts worldwide for the supply of cyclones for the specialized FCC application.

Over thirty-five of these contracts are for tertiary installations, of which about half are utilized solely for final particulate removal to meet local air pollution control regulations.  The balance of these units are located ahead of Power Recovery Turbines (PRT) and provide protection for the turbines, as well as reduce catalyst emissions to atmosphere.

All the installations ahead of a PRT, of course, are designed to handle the flue gas at essentially the elevated regenerator temperature and pressure and are contained in their own pressure vessels.
