In the elutriation leg of a commercial crystallizer containing a mixture of coarse and very fine crystals of the same material, a liquid is pumped vertically upward. The liquid velocity is adjusted such that it is slightly lower than the terminal velocity of the coarse crystals only. Hence
  • a)
    the very fine and coarse crystals will both be carried upward by the liquid
  • b)
    the very fine and coarse crystals will both settle at the bottom of the tube
  • c)
    the very fine crystals will be carried upward and the coarse crystals will settle
  • d)
    the coarse crystals will be carried upward and the very fine crystals will settle
Correct answer is option 'C'. Can you explain this answer?

In the elutriation leg of a commercial crystallizer containing a mixtu...
Explanation:

In the elutriation leg of a commercial crystallizer, a mixture of coarse and very fine crystals of the same material is present. A liquid is pumped vertically upward in the crystallizer. The liquid velocity is adjusted such that it is slightly lower than the terminal velocity of the coarse crystals only. Hence, the following phenomenon will take place:

a) The very fine and coarse crystals will both be carried upward by the liquid
This option is incorrect because the velocity of the liquid is lower than the terminal velocity of the coarse crystals only. Thus, the very fine crystals will not be carried upward.

b) The very fine and coarse crystals will both settle at the bottom of the tube
This option is incorrect because the liquid is pumped vertically upward in the crystallizer. Hence, the crystals will not settle at the bottom.

c) The very fine crystals will be carried upward and the coarse crystals will settle
This option is correct because the velocity of the liquid is lower than the terminal velocity of the coarse crystals only. Thus, the very fine crystals will be carried upward as their terminal velocity is lower compared to the velocity of the liquid. The coarse crystals, however, will not be carried upward as their terminal velocity is higher compared to the velocity of the liquid. Hence, the coarse crystals will settle at the bottom.

d) The coarse crystals will be carried upward and the very fine crystals will settle
This option is incorrect because the velocity of the liquid is lower than the terminal velocity of the coarse crystals only. Thus, the coarse crystals will not be carried upward.
