Notes:
The minimum fluidization velocity is an important parameter in the design and operationof an industrial unit of fluidization. In the present work the minimum fluidization velocities of fineparticles were obtained through two experimental methodologies. The first one is the classicprocedure to determine that parameter analyzing the diagram of medium pressure drop in the bed infunction of the superficial gas velocity, during the defluidization of the bed. And the second is thetechnique of identifying the minimum fluidization velocity interpreting the behavior of thenormalized standard deviation of the pressure drop in the bed. A cylindrical bed of transparentacrylic was used in the process and the used particles were glass spheres, FCC and zinc powder. Tocompare the precision of the two methodologies some equations that predict the minimumfluidization velocity were used
