A solution of 500 kg of Na2S04 in 2500 kg water is cooled from 333 K to 283 K in an agitated mild steel vessel of mass 750 kg. At 283 K, the solubility of the anhydrous salt is 8.9 kg/100 kg water and the stable crystalline phase is Na2SO4.10H2O. At 291 K, the heat of solution is —78.5 MJ/kmol and the specific heat capacities of the solution and mild steel are 3.6 and 0.5 kJ/kg deg K respectively. If, during cooling, 2 per cent of the water initially present is lost by evaporation, estimate the heat which must be removed. [Pg.230]

Quantitatively, these two isolates differ in their initial solubilities in water and in the magnitude of the salt effects. For a given salt, DPI is on the average salted out twice as much as NPI. Our data agree qualitatively with those of Hermansson (4) except for the lack of a minimum in the Na2SO4 curve. [Pg.99]
