The suitable range of ammoniater concentration and loading (mol CO /mol NH 3 ) were decided in the point of view of absorption capacity and NH 4 precipitation. The absorption capacity of and the precipitation of NH 4 in liquid phase were calculated by the Pitzer model for electrolyte solution. The absorption capacity of the ammoniater over 5 O was higher than that of conventional amine absorbent. The loadings where precipitation occurred were decided at various absorbent concentrations. Theses values were higher than 0.5 in the concentration range of 5-14 O at 93, 313 K. The absorber for the removal of in flue gas could be operated without NH 4 precipitation by using high concentration of ammoniater below these loading values. The optimum temperature of the ammoniater absorbent for removal of in flue gas was K depending on the concentration of ammoniater.
