Hydrolytic degradation process

Dear sea friends, why is the concentration of the ammonium carbonate solution in the CO2 stripping urea production process much higher than that in the water-based solution full-circulation method? ? ?
Is it related to the difference in their water-carbon ratios?

Why is the concentration of ammonium carbonate in the urea production process using the CO2 stripping method much higher than that in the process with full water circulation? The proper CO2 stripping process should have an ammonia concentration of over 3%, and a CO2 concentration of over 2%. As for the concentration in aqueous solution processes, it is necessary to look up relevant information.
In the ammonium carbamate solution obtained through the stripping method that we went to examine, the NH3 concentration is around 8-10%, while the CO2 concentration is between 5-8%. In the aqueous solution, the NH3 concentration is about 3.5%, and the CO2 concentration is 1-2%. Why is this? Please explain ? ? ? ?
