I'm going to calculate a model that is CO2 capture device using ammonia solution as following image.

7% ammonia solution is in a container and CO2 is injected from the bottom of the container. Injected CO2 reacts with ammonia solution and CO2 is captured.
Basic chemical reactin equation is follows(omitted details).

NH3(l)+H2O(l)+CO2(g) NH4HCO3(aq)

But, I don't know how to calculate this problem, how to decide the multiphase model(mixture?) and how to realize the chemical reaction and etc.
Please Advice to me.
