Material properties: A mixture containing ammonium chloride (NH4Cl) and potassium dihydrogen phosphate (KH2PO4), with a pH of 4.7–4.9; the boiling point of this solution is 110 degrees. Requirements for the concentration of the material in and out of the system: the initial solution should contain 150–200 g/L of chloride ions and 60 g/L of nitrogen; concentration should be reduced to 120 g/L of nitrogen at which point concentration processes should be stopped, and the mixture should be cooled to allow crystallization and separation of ammonium chloride (NH4Cl)； The mother liquor is further concentrated through two-stage evaporation, increasing the potassium oxide (K2O) concentration from 70 g/L to 120 g/L. Material used: titanium (or titanium for the parts in contact with the material); the defoamer separator is made of glass-lined steel (if feasible; otherwise, 316L is used). I’m not very familiar with the parameters related to the material composition – I’m poor at chemistry. Could someone with more knowledge explain this?
