    Is anyone else concerned about maximizing their catalyst.  Specifically in the area of leaks, fugitive emissions, etc.,  what should we be monitoring?
     
    Thanks in advance,

    With the price of catalyst we should all be concerned. There’s a couple of things that can help.  Good flow distribution and closley monitoring the temperature of your reactor can minimize catalyst loss.

    The next step in emissions reduction is 4th stage separation to remove more catalyst fines from FCC Fluegas. These systems are typically installed downstream of the cyclonic separators. Let me know if you would like more information.

    Pollard Industries, LLC and Dahlman have introduced a new Fourth Stage Seperator (FSS) design for the removal of catalyst fines from FCC Flue Gas coming from the 3rd Stage Seperator. Let me know if you need more details. Our number is 1-866-813-3507.
     
    Dahlman also has systems in operation filtering FCC Slurry Oil, and we have been working on applications for the filtration of feedstocks to hydrotreater and hydrocracker to prolong catalyst bed life.

    Cyclone Velocities are crucial in order to minimize catalysts losses.  The licensor should be able to give a bulk part of what the velocities are.  However, this numbers are always very conservative.  If you have catalysts losses in the Regenerator there is a high chance that you cyclones are damaged.
