    Effect of pH on dissolution of iron sulfide scales using THPS by Ahmed, Musa

    Published 2019
    “…For the field scale the combined formulation of THPS and EDTA yielded more than 70 % scale solubility however, for pure pyrite it was less than 10%. This implies that THPS and EDTA combination is effective in dissolving other iron sulfide scales, such as pyrrhotite (Fe7S8) and troilite (FeS) which are more soluble in comparison with pyrite. …”
