Dual-alkali method for desulfurization
Thread Content
We used the double-subtraction method for the 130-ton boiler, and the results were good; there was no blockage in the pipelines either. It requires technical expertise
In theory, scaling should be minimal in the double-alkali process, but many photos from actual plants show severe scaling and clogging problems, which is likely related to process simplification and maintenance issues
May I ask which company the original poster works for? Very interested in the double-alkali method
Our company also uses the double-alkali method for desulfurization; the original nozzles tended to get clogged and did not provide good results, but things improved after we replaced them
A major drawback is congestion. Could you share your company’s experience in maintenance?
Our company is now switching from the double-alkali method to the single-alkali method; the costs are too high, and we don’t know how to handle this wastewater
Same question: how to treat wastewater using the single-alkali method? A company claims that their desulfurization liquid does not need to be discharged outside; it can simply be recycled by adding alkali. I have serious doubts about this – do you think it’s feasible?
