Title: fractional crystallization
Post by: sadegh66 on September 28, 2015, 06:30:42 PM
Hi all,
I do research on Fractional Crystallization of brines. My goal is to recover salt and magnesium compounds.I set the brine samples in various temperature to separate various salts after supersaturation.this operation will be continuously. Is this software can help me?

Perhaps. You can calculate saturation states, precipitate to equilibrium, or develop rate expressions for precipitation. You definitely want to use the Pitzer approach (pitzer.dat database). Provided the elements you are interested in are parameterized in pitzer.dat, I think it should be useful.

thank you
can use In this software from several processes Simultaneously and Reel?
for example, Can I use from crystallization, precipitation and adsorption reelly?

You can use multiple kinetic reactions (a KINETICS definition) in combination with sets of other reactants, for example multiple equilibrium phases in an EQUILIBRIUM_PHASES definition and multiple surfaces in a SURFACE definition.
