HOU Scale Remover (ETI-980) is made from a blend of chemicals that form soluble, complex molecules with iron ions. ETI-980 was specifically developed to react with iron sulfide (FeS) in the troilite form (present in packing or demisters; usually adopt hexagonal symmetry) and the mackinawite form (present in trays or walls, with a layered structure), which means ETI-980 will dissolve most of the scale founded in a refinery.
