It is desired to produce 1000 kg/h of Na_3 PO_4.12H_2 O crystals from a feed solution containing 5.6 wt % Na_3 PO_4 and traces of impurity. The original solution is first evaporated in an evaporator to a 35 wt % Na_3 PO_4 solution and then cooled to 293 K in a crystallizer, where the hydrated crystals and a mother-liquor solution are removed. One out of every 10 kg of mother liquor is discarded to waste to get rid of the...

solubility curve of salts
Solubility Curve of Salts ( Extra Credit: Maximum of 5 pts.) The solubility curve for solutes describes at what the temperature its solution will be saturated (maximum solubility). Beyond that amount, the salt will start to crystallize. The solubility of sodium chloride and potassium chloride in water at different temperatures is given in the table below: Naci КСІ Temp (C) Solubility (g/100g H2O) Temp (C) Solubility (g/100g H,O) 0 35.65 28 10 35.72 35.89 20 30...
