Abnormal water color in flue gas desulfurization tower
Thread Content
I would like to ask fellow sailors and experts: why is the water in the flue gas desulfurization tower of the catalytic unit green?
The green color of the water in the flue gas desulfurization tower may be due to the following reasons: 1. **High levels of heavy metal ions such as copper or chromium**: If the water contains high concentrations of heavy metal ions like copper and chromium, it can cause the water to take on a green color. 2. **Chemical reactions**: Some of the chemical reagents used in the desulfurization process, or the by-products resulting from the reaction between pollutants and desulfurizing agents, may be green in color. 3. **Microbial activity**: Under certain conditions, if the environment inside the flue gas desulfurization tower is suitable for the growth of microorganisms, such as certain types of algae or bacteria, it may cause the water to change color. 4. **Corrosion issue**: Corrosion of the equipment causes copper or other metal ions to dissolve into the water, which can also lead to a change in the water’s color. It is recommended to conduct a thorough examination of the water sample for analysis, in order to identify the specific source and causes of pollution, and to take appropriate corrective measures. .
The smoke contains catalyst dust, which may contain heavy metals; it may also be alkaline in nature, leading to a green color
What is the principle behind its slightly alkaline and light green color?
We have seen black colors, which was caused by incomplete combustion in the CO incinerator; red colors have appeared as a result of alkali slag entering the alkaline solution
Caused by corrosion of equipment in the flue gas system?
