Concept explainers
(a)
Interpretation:
A plot of solubility as a function of temperature that can be used for interpolation should be plotted.
Concept introduction:
A hydrophilic pressure is one which shows higher attraction towards water molecules and other polar molecules than the oils and the other hydrophobic solvents. Serine is a non-acidic amino acid which shows higher hydrophilicity than any other amino acid.
(b)
Interpretation:
To estimate the mass of crystals produced per unit mass of feed solution and the fraction of serine fed that is recovered as crystalline product.

(c)

Concept introduction:

(d)
Interpretation:
To explain reason for the serine is more hydrophilic than most other amino acids.
Concept introduction:
Because of the bonding which is uneven in the molecules they have partial charges that makes the molecules polar. A good example for the polar substance is water. In the water molecules the atom oxygen takes the electrons closer to it and that gives the electro negativity for the atom. As the water is hydrophilic it dissolves in other polar substance like water or the solvent that is watery.
(e)
Interpretation:
To sketch a flowchart for a process in which the methanol fed to the crystallizer in Part (c) is recycled.
Concept introduction:
The methanol crystallization is optimized by the RSM which is known as the response surface methodology along with the D optimal design. The developing procedure of the solvent crystallization is based on the parameters.
