Claim:
1. A system for injecting catalyst and/or additives into a fluidized catalytic cracking unit, comprising: (a) a dust collector in fluid communication with at least one storage bin holding one of the catalyst and/or additives; (b) a vacuum producer in fluid communication with the dust collector so that the vacuum producer generates a vacuum within the dust collector that draws the one of the catalyst and/or additives into the dust collector; (c) a filter positioned within said dust collector and operatively adapted to filter fluid exiting said dust collector in response to a vacuum produced by said vacuum producer; (d) a transfer pot in fluid communication with the dust collector for receiving the one of the catalyst and/or additives from the dust collector, the transfer pot being in fluid communication with the fluidized catalytic cracking unit and a source of pressurized air; and the one of the catalyst and/or additives is transferred to the fluidized catalytic cracking unit in response to one or more system parameters; and (e) at least one differential pressure gauge having a differential pressure gauge component positioned so as to measure a pressure of said dust collector.
