    What type of Corrosion

    CUI is definitely a concern in your tank. Review your tank's insulation to prevent water ingress, measure the thickness on the most corroded plates and calculate whether the remaining thicknesses support your tank's MAWP. If so, apply a proper painting procedure and insulate your tank properly.

    CDU overhead wash water injection quill plugging

    CDU overhead wash water injection quill plugging

    Yeh! Amonium chloride is the strongest possibility, I don´t see a way to unplugg it on line. Water wash is normaly done in air cooler boxes sections trough 2 inch lines. I think you have to ponder a modification control in your CDU overhead wash water injection.
