An aqueous solution of na2co3 saturates at 300k to form na2co3.h2o crystals. 10kg/h of 35 mass % aqueous solution enters a continuous evaporative crystallizer at 335k and 15 kpa.
additional information:
a) the boiling point rise of the solution is 12k
b) the heat of crytallization is 175 kj/kg
c) the mean heat capacity of the solution is 4.2 kj/kg
d) at 1.5kpa water boils at 286k and the latent heat of vaporization is 2470 kj/kg
e) over the temperatue range 270 k and 350 k the solubility of na2co3 in water is given by: solubility = 0.55t - 127.6 kg/100kg water
1.1) draw a schematic diagram that depicts the crystallization process showing all the entering and leaving streams with the given information. (4)
1.2) determine the actual evaporation rate (8)
1.3) determine the yield of crystals and solution formed using the mass balance method
