The reactions and equilibrium relationships underlying the absorption
process of CO2 gas in ammoniated brine solutions as proposed in part 1
are described first. A numerical solution of a set of nonlinear equat
ions developed in the form of an algorithm, to calculate the concentra
tion of unreacted ammonia, is obtained next. Calculated values are com
pared with experimental data for the system under investigation. The i
nstantaneous absorption rate is evaluated by using the approximate app
roach (film model) and the exact solution (penetration theory).
