Study on Multi-stage liquid-solid semi-fluidization with spherical particles


DK Samal, YK Mohanty, GK ROY

Multi-stage chemical process or operation gained the credit over single stage in many case. For getting advantage of multi-stage over single stage semi-fluidization on hydrodynamic characteristics investigation has been carried out in a Perspex column of 25.4 mm internal diameter. Glass beads are used as solid phase with water as the fluidizing medium. Stainless steel screens have been used as top and bottom grids as well as the intermediate restraints. Experimental parameter studied includes superficial liquid flow rate, no. of stages with constant bed expansion ratio. Mathematical study and graphical analysis have been done by introducing a new parameter “D-power factor” for multi-stage semi-fluidization. Total power analysis shows that the power consumption is less as compared to the single stage for identical bed conditions for multi-stage semi-fluidization.
