In the carbon dioxide stripping urea process, what are the factors that affect the pH value of the recovered waste liquid?

I would like to ask the experts: in the carbon dioxide stripping urea process, what are the factors that affect the pH value of the waste liquid obtained after separation?
OP, is synthetic ammonia based on gas or coal? Is the decarbonization process low-temperature methanol washing, or something else? Different decarburization processes have varying effects on desorption.

Analyze the methanol content in the CO2 feed gas. The pH of the desorption waste liquid with a high methanol content is low.
The methanol content is generally below 100 ppm, with little variation, but the pH value fluctuates.
What is the pH value? Waste liquid conductivity?
We will only look at conductivity, urea and ammonia levels; pH value is not considered
What is your typical conductivity value?
