Fluidization Engineering

Entrainment at or Above the TDH-Single Size of Solids

Question 1
Marks : +2 | -2
Pass Ratio : 100%
Which type of materials are used to experiment the elutrition of particles?
Sand
FCC catalyst
Glass spheres
All of the mentioned
Explanation:
From table of ‘experimental conditions of fines’.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
At what velocity entrainment of particles in the fluidized bed takes place?
At minimum fluidization velocity
At terminal velocity
More than terminal velocity
At superficial velocity
Explanation:
At terminal velocity entrainment starts, when velocity is more than terminal velocity complete entrainment takes place.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
How to distinguish between Entrainment and Elutrition?
Based on segregation of particles
Based on velocity of gas
Based on height of reactor
All of the mentioned
Explanation:
Entrainment leads to removal of all particles and Entrainment leads to removal of specific particles.
