I would like to ask some questions regarding the pH of the steam flash tank generated as a by-product in the HCl synthesis furnace
Thread Content
Dear experts, my company has recently installed a hydrochloric acid synthesis furnace that generates by-product steam. The flash tank uses deionized water, and over the course of several days of testing, its pH remained between 5 and 6. Everything else is normal. It has now been ruled out that a leak is causing the pH to become acidic; I would appreciate it if experienced experts could advise me on what might be causing this issue and what testing methods are available Thank you all
Chemicals need to be added, and deoxygenated water should be used; otherwise, this air pocket will corrode
The pH of deionized water is generally between 6 and 7; in our hydrochloric acid furnace, we add a little sodium tripolyphosphate, which results in a pH of 9.5 to 11； The pH of hydrogen boilers should be controlled between 10 and 11.5
Add a chemical dosing unit to adjust pH
