What are the main process parameters in the production operation of salt refining? The main process parameters for the salt dissolution step in a brine purification production operation are as follows: steam pressure of 0.4–0.7 MPa; brine temperature of 50–60°C; density of the crude brine of 1190–1200 Kg/m3 (at a temperature of 50°C); and the crude brine contains 310±5 g/l of NaCl
Isn’t there a one-to-one relationship between the density and concentration of saltwater? Here, the control parameters we have are not density; only the concentration of saturated salt water and the temperature of the salt water
Simply by adding salt, the concentration and temperature of the brine can be kept stable; it is best to add the salt evenly. It doesn’t really matter what the steam pressure is.
Concentration values are generally unique, whereas density values are affected by temperature. It can only be said that at a specified temperature, there is a corresponding relationship between the density and concentration of saltwater.

Sodium chloride, sodium hydroxide, pH, ClO-, turbidity, calcium, magnesium, concentration of ferric trichloride solution, concentration of barium chloride solution, etc
Steam is a necessary condition to maintain the temperature of the brine; the pressure doesn’t matter. It can only be said that your plant has enough steam.
