(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.

(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.

- Example (6): An evaporator is concentrating F kg/h at 311K of a 20wt% solution of NaOH to 50wt %. The saturated steam used for heating is at 399.3K. The pressure in the vapor space of the evaporator is 13.3 KPa abs. The 5:48 O Transcribed Image Text: Example (7): Determine thearrow_forward14.9. A forward feed double-effect vertical evaporator, with equal heating areas in each effect, is fed with 5 kg/s of a liquor of specific heat capacity of 4.18 kJ/kg K. and with no boiling point rise, so that 50 per cent of the feed liquor is evaporated. The overall heat transfer coefficient in the second effect is 75 per cent of that in the first effect. Steam is fed at 395 K and the boiling point in the second effect is 373 K. The feed is heated by an external heater to the boiling point in the first effect. It is decided to bleed off 0.25 kg/s of vapour from the vapour line to the second effect for use in another process. If the feed is still heated to the boiling point of the first effect by external means, what will be the change in steam consumption of the evaporator unit? For the purpose of calculation, the latent heat of the vapours and of the steam may both be taken as 2230 kJ/kgarrow_forwardExample(3): It is desired to design a double effect evaporator for concentrating a certain caustic soda solution from 12.5wt% to 40wt%. The feed at 50°C enters the first evaporator at a rate of 2500kg/h. Steam at atmospheric pressure is being used for the said purpose. The second effect is operated under 600mmHg vacuum. If the overall heat transfer coefficients of the two stages are 1952 and 1220kcal/ m2.h.°C. respectively, determine the heat transfer area of each effect. The BPR will be considered and present for the both effect 5:49arrow_forward
