Acidic water stripping tower for dry gas hydrogen production

The condensed water from the medium-pressure gasifier in this system enters the stripping tower where it is stripped; the purified water resulting from this process then goes into the deaerator. I would like to ask fellow sailors: what parameters need to be controlled for the purified water exiting the stripping tower in order to ensure that it meets the requirements for use in the deaerator?
It’s mainly PH, to check the stripping effect; otherwise, it causes excessive corrosion to pumps, pipelines, and deaerators! The function of a stripping tower is to remove carbon dioxide; other stripping towers cannot be controlled either, and the quality of the steam supplied must be taken into consideration! Ultimately, it’s still the quality of the demineralized water!
How is the reuse effect on your end? Generally, the pH should be kept at least at 7, the iron ion content should be controlled at 50 ug/g, and conductivity also needs to be monitored
