Recently, there have been black spots in the circulating acid of the dry absorption system. Have any experts encountered a similar situation? Solve it, thank you
Please ask the experts to analyze the reasons
Is natural gas being burned in the melting and pyrometallurgical furnaces? Are the furnaces shut down for insulation?
Dryness: which is more, one inhalation or two?
Check for any foreign objects entering the acid tank, verify whether there are issues with the material of the demister gaskets, and check if the fibers have faded
This has also occurred in copper smelting enterprises before; subsequent analysis showed that it was caused by the peeling off of dry-set building mortar.
