How significant is the effect of adding liquid alkali in ammonia-based desulfurization, and will it exacerbate equipment corrosion?
Thread Content
Recently, the level of free ammonia in the ammonia-based desulfurization process in the desulfurization unit was as low as 8.5 mg/l (due to the rainy season, less secondary liquid is discharged, which affects the preparation of concentrated ammonia solution). As a result, the company proposed conducting an experiment involving the addition of alkali to the desulfurization solution. Colleagues, I wonder if anyone has conducted any experiments or has other good suggestions; I hope everyone will feel free to share their unique perspectives. Thank you
Check what the temperature of your gas is Adding alkali has an impact on the oxidative regeneration of the desulfurization solution; in particular, significant changes occur in the electrode potential. It is recommended not to add alkali, but rather to control the temperature of the gas and the desulfurization solution properly in order to achieve a dynamic equilibrium of ammonia. If you have any questions, let’s discuss them together. My QQ number is 347380495
The gas temperature is 40 degrees; the refrigerator has not been turned on yet.
