Materials selection for the evaporation of sodium sulfate solutions containing fluoride and chloride ions
Thread Content
For a 10-20% sodium sulfate solution containing approximately 70 mg/L of fluoride ions and 50 mg/L of chloride ions, what material should be used for the evaporation equipment to resist corrosion?
It depends on the equipment used for evaporation! Our company offers reaction vessels equipped with evaporation and stirring functions, and the evaporation efficiency is 1.5 to 2 times higher than that of frame-type or anchor-type units. The principle is that the heat transfer area remains constant during the evaporation process. Since the material contains fluoride ions, it is recommended to use fluorinated coating materials.
