Abstract
The present invention is a method for non-intrusively monitoring the chemical and physical processes associated with gas generation in the feed riser of a cat-cracker and the correlation of those changes in these processes to changes in the output product produced the cat-cracker. The method includes the steps of measuring RMS accelerations along a feed riser at one or more positions, determining the initial RMS acceleration at each of these positions when the unit is operating at its desired performance, comparing the measured FRP to the reference FRP when said reactor is operating at its desired performance and determining the reference FRP, and determining the change in the FRP.
