ABSTRACT:
The present invention relates to dynamically controlling the expansion of a fluid bed reactor system. By mounting a density detector to a floating body that floats on top of the carrying medium in the fluid bed, one can detect the density at a certain position that is level with the sensor head of the detector. Upon comparing the density detected with a pre-determined density, the flow velocity of the carrying medium is adjusted accordingly.
