Analysis of acidic water in the reflux tank at the top of the regeneration tower
Thread Content
What is the reason for the high iron ion content in the acidic water in the regenerator top reflux tank?
Could it be that it’s the first time driving, and the iron in the system has entered the solvent?
Generally, acidic water is not analyzed for iron ions. Do you analyze this parameter frequently? If not, why produce iron ions? What is the high level of iron ion content?
In routine laboratory analyses, iron ions are usually not analyzed; I’m not sure why you are doing it The high level of iron ions may be due to excessive thermally stable salts in the system, which cause significant corrosion of the amine solution system, leading to the formation of more ferrous sulfide that then ends up in the acidic water.
OP, what material is used for your acidic water pipelines? What is the level of iron ions in acidic water?
Reply 1# wkqkaken: In my opinion, the sulfur compound content in your acidic water is relatively high, which causes severe corrosion to pipelines and equipment during the production process. Substances such as ferrous sulfide produced end up entering the treatment units along with the acidic water, leading to this phenomenon
