ammoniacal brine
1.The mechanism and kinetics of the carbonation process of the ammoniacal brine were analysed in this paper. Chemical reactions involved in the carbonation process were considered as three consecutive and reversible steps: the first reaction between CO 2 and NH 3 is a fast one, which takes place within the liquid film, while the hydrolysis of NH 2COO - and precipitation of NaHCO 3 are slow reactions and taken place in the liquid bulk.
