In this paper the modeling and the simulation for carbonation process of ammoniacal brine solution have been described. Carbonation process of ammoniacal sodium chloride solution (brine) is used to obtain sodium bicarbonate and sodium carbonate in soda ash plants (Solvay technology). Carbonation process of ammoniacal brine is a complex process because of the following aspects: three phase system, equilibrium reactions and precipitation of sodium bicarbonate. Computer Aided Design (CAD) software packages, among which ChemCAD is very often used, are new tools for chemical process analysis and design, having advantages versus the traditional ways of design. The mathematical model of the carbonation process was simulated using ChemCAD. The simulation results were compared with data collected from real plant operation in order to validate the application developed for the process. From the simulation results, very valuable information can be obtained regarding real plant operation.
