I would like to ask everyone for ways to address the high level of iron ions in the condensate water produced during hydrogen production

Our system requires that the iron content in the condensate water not exceed 300. If it meets this standard, the water can be sent outside; otherwise, it is diverted to an internal use process to serve as part of the feedwater for the deaerator. But the iron ion level will definitely be too high the day after it passes the quality inspection for delivery. So I would like to ask everyone how to deal with iron in condensed water?
Generally, it is necessary to keep the pH value of the boiler feedwater between 8.5 and 9.2, with the total iron content being below 50 ug/g. Based on what you’ve described, it seems to be a water supply issue. It is possible to conduct tests on the quality of boiler feed water as well as on the quality of condensate water; these results can be compared over several days, and finally the data can be analyzed to make adjustments.
The problem with the conversion catalyst is the loss of iron ions into the condensate water. To solve it fundamentally, replace the catalyst
The pH of our boiler water remains quite stable. However, the iron level in the furnace water fluctuates; it can reach over 200 at times. Is increasing the regular discharge the solution?
After this change in operation, CO has remained around 3. The temperature is the same, but CO is higher than before; I also suspect there is a problem with the intermediate variant. May I also ask what is the typical lifespan of a medium-frequency transformer?
Do you mean the condensate water by which you refer to the water that comes out of the several water separation tanks after hydrogen production? Some companies add high-temperature corrosion inhibitors to this kind of water.
Yes, it is the water from the liquid separation tank after medium transformation. Thank you!
