What are the impacts of a small temperature difference in the CO2 stripping process on the entire system?

1. Declining conversion rate? 2. Is the low-voltage load heavy? 3. Is the evaporation load high? 4. Are high-profile water heat exchangers prone to clogging? 5. Has the low-pressure steam production decreased? 6. Does the concentration of low-pressure ammonium solution decrease or increase? (We are lower than the normal design value; it should be higher, right?) 7. Increased moisture content in the finished product?
First, we need to figure out the reason for the decrease in temperature difference. I think a small temperature difference has an impact on 1, 2, and 4, while it has little effect on the others.
The high-temperature water heat exchanger is clogged, with a temperature difference of only 1 degree – what impacts does this have on the system?
The absorption efficiency of the high-pressure scrubber decreases, gas-phase condensation is poor, the pressure in the high-pressure system rises, ammonia consumption increases, and sometimes even the suction capacity of the ejector declines.
Leaks in the internal components of the high-pressure washer can also result in a small temperature difference in the high-pressure water, or even no temperature difference at all
