Will the high sulfate content in the gas generation cycle water cause corrosion at the bottom of the fixed-bed gas generation furnace?
Thread Content
The gas generation furnace in our plant is of fixed-bed type, and the sulfate content in the gas generation circulating water is 20,000 mg/L. May I ask if bottom corrosion is related to sulfate ions? What methods do you use to address the corrosion issue at the bottom of the gas generation furnace? Are there any methods to deal with sulfate in the gas generation cycle water?
Precipitation of sulfate ions and calcium ions in the gas generation cycle water
Will the precipitation of calcium ions cause scaling in the equipment?
Where does the sulfate in circulating water come from? It’s better to control it at the source!
If calcium ions are to be added, how should one make a choice? Adding CaCl2 introduces a large amount of chloride ions; will this exacerbate corrosion? If CaO is added, how can dissolution be ensured?
