How to use NaOH and Na3PO4 to adjust the pH system of waste heat boiler drum?
Thread Content
The synthesis tower of our plant leaked, and the production gas leaked into the steam system. Now it is not the scheduled shutdown time. We found that the pH of the steam drum discharge was as low as 6.5. We increased the trisodium phosphate treatment but still could not adjust it. We analyzed that the acidic gas CO2 in the production gas may be causing harm. Can we add NaOH to adjust it? Urgent! Urgent! ! ! ! ! ! ! ! ! ! ! ! !
Please tell me the ratio of NaOH, how many milligrams per liter of boiler water?
Some people have suggested that alkali embrittlement may occur when adding NaOH, is this possible?
