摘要：

A mathematical model has been developed for the absorption of carbon dioxide from ammonia synthesis gas in amine-promoted hot potassium carbonate solution. The model uses vapor-liquid equilibrium data for the unpromoted carbonate-CO2 system, which seems to be adequate at low fractional saturation of the liquid with carbon dioxide. In the temperature range of industrial operation, instantaneous reaction rate provides the appropriate enhancement factor for the chemical absorption. The calculated results have been found to be in close agreement with the observed values for two industrial units. The model has been used to calculate various flow, temperature, and concentration profiles in the absorber.
