An 80°C aqueous solution containing 58 wt% sodium nitrate (NaNO3) is fed to a combination crystallization-settling unit operating at 25°C. The unit separates crystals from the remaining solution. If the feed to the crystallizer/settler unit is 1000 kg/hr, what is the production of dry crystals and the mass of the exiting solution? If the exiting solution is then fed to a second crystallizer-settler and 50 kg/hr of crystals were produced in the second unit, what is the operating temperature of the second crystallizer? See next page for solubility curve.
