The transformation uses an NDC desulfurization solution; the reason for the increase in hydrogen sulfide at the outlet
Thread Content
The transformation uses an NDC desulfurization solution, and the alkalinity of the solution has also been increased; what is the reason for the increase in hydrogen sulfide at the outlet?
1. It is recommended to analyze the NDC content. We also use NDC, but we keep its content between 60 and 80; it does not reach the level of over 120 recommended by the manufacturer, and the results remain relatively stable. 2. Standardize operations such as alkali fusion.
If the component level rises and cannot be controlled, is draining the only option?
The description is too simple to make a judgment. From what I know personally, NDC yields better results than traditional methods. On the other hand, analysis and standardized procedures should also be avoided in terms of equipment and operation; it is better to pay more attention to the guidance provided by the manufacturer
