The image above represents the height of a fluidized bed. To calculate the height of the fluidized bed, three essential parameters are needed, and these parameters are Distance Bubble Must Travel (K), Mass Transfer Coefficient for Bubble 1 (VB1), and Mass Transfer Coefficient for Bubble 2 (VB2).
The formula for calculating the height of a fluidized bed:
ΔZ = K In(VB1/VB2)
Where:
ΔZ = Height of Fluidized Bed
K = Distance Bubble Must Travel
VB1Â = Mass Transfer Coefficient for Bubble 1
VB2Â = Mass Transfer Coefficient for Bubble 2
Let’s solve an example;
Find the height of the fluidized bed when the distance bubble must travel is 16, the mass transfer coefficient for bubble 1 is 4, and the mass transfer coefficient for bubble 2 is 28.
This implies that;
K = Distance Bubble Must Travel = 16
VB1 = Mass Transfer Coefficient for Bubble 1 = 4
VB2 = Mass Transfer Coefficient for Bubble 2 = 28
ΔZ = K In(VB1/VB2)
ΔZ = 16 In(4/28)
That is, ΔZ = 16 In(0.142)
ΔZ = 16 (-1.945)
ΔZ = -31.134
Therefore, the height of fluidized bed is -31.134 m.
