The iron content of number 2 scale sample is 3%; iron content is higher than that of iron ions in water at a percentage of total cations, and there is a certain degree of corrosion; ferrous sulfide scaling also blocks the pipeline.
It is being widely used in the oil industry due to its capacity of dissolving the ferrous sulfide. Its main advantage is its low environmental toxicity [17].
This color is a consequence of a reaction that produces a harmless compound named ferrous sulfide (or iron(II) sulfide).
where [[H.sup.+]] is the hydrogen ion concentration, [K.sub.1] and [K.sub.2] are the first and second ionization constants for [H.sub.2]S, and [K.sub.FeS] is the solubility product for ferrous sulfide. The solubility of a heavy metal [M.sup.+2] is then given by
