Simulation of salt waste evaporation/crystallization.

摘要

The database of ProChem software has been enhanced to account for the formation of the mineral, Burkite which can form in alkaline tank wastes during evaporation. This mineral was not suspected until recent evaporation/crystallization studies suggested its presence. The enhanced data base will predict its occurrence and realm of existence. If salt cake temperatures drop below 30(degrees)C the Burkite phase is unstable toward hydrated sodium carbonates and sulfates. ProChem will not predict if this phase is more or less rapidly dissolved than its component salts. The enhanced database improves our ability to simulate waste chemistry.
