Physical properties of circulating mother liquor for heavy soda ash produced by hydration process
Thread Content
I am doing the process design of a heat exchanger. I am using the calciner gas of heavy soda ash to heat the circulating mother liquor of heavy soda ash in the hydration method. Does anyone know the physical properties of the circulating mother liquor? The specific heat and density of 32-80 degrees Celsius are roughly known. I want to know the viscosity and thermal conductivity. I hope friends who know it can give me some advice. Thank you in advance.
Generally, in normal production, the mother liquor needs to be cooled down and rarely heated.
The concentration of the liquid phase hydration method mother liquor is around 125tt, and the salt content is less than 15tt. This should be checked in a table. The temperature is about 85 degrees, but why do we need to use furnace gas to heat it?
If you use heavy ash furnace gas, it shouldn't have very good results, right?
