Abstract:
1. A method for determining a size of at least one of a plurality of particles in a fluidized bed reactor, the method comprising: measuring a gas pressure in an inlet of the reactor with an inlet pressure sensor; communicating the measured gas pressure in the inlet of the reactor to a processor; determining, using the processor, the size of at least one of the plurality of particles in the fluidized bed reactor based at least in part on an algorithm applied to the gas pressure in the inlet of the reactor measured by the inlet pressure sensor; and controlling the operation of the fluidized bed reactor based at least in part on the determined size of at least one of the plurality of particles in the fluidized bed reactor, wherein controlling operation of the fluidized bed reactor includes increasing the flow rate of gas within the fluidized bed reactor when the determined size of at least one of the plurality of particles exceeds a threshold level.
