摘要： A method for continuous monitoring the presence of entrained catalyst in a regenerator flue gas stream of a fluidized catalytic cracking unit is provided. The method has the following steps: (a) passing the regenerator gas stream through a separation system to remove a portion of the catalyst fines and to create a cleaner regenerator gas stream; (b) collecting a sample portion of the cleaner regenerator gas stream and directing the sample portion of the cleaner regenerator gas stream through an inertial separating device to separate entrained catalyst from the sample portion of the cleaner regenerator gas stream; (c) collecting any separated catalyst from the inertial separating device; and (d) monitoring the efficiency of the separation system by analyzing at least the amount of the collected separated catalyst or the particle size of the collected separated catalyst. An apparatus for measuring the amount of potentially erosive catalyst fines in a regenerator flue gas stream in a fluidized catalytic cracking unit is also provided. The apparatus is a sampling probe for collecting a sample portion of the regenerator flue gas from a line through which the regenerator flue gas stream flows, and an inertial separating device located downstream of the sampling probe and in fluid communication therewith, for removing any entrained catalyst fines from the sample portion of the regenerator flue gas.
