Abstract
The liquid-vapour equilibrium states for NH3, CO2 and H2O in the range of technological parameters of ammonia absorption and carbonation pro cesses in the Solvay's method were determined. The region of the occur rence of metastable state of the NH3-CO2--H2O-NaCl system was determin ed and dynamics of changes of liquid and gas phases composition and eq uilibrium pressure changes during disappearance of carbamate and bicar bonate supersaturation was described.
