Gypsum scale typically forms via natural oxidation when the frac tion of calcium sulfate in the slurry (slurry oxidation level) is greater than 15%. In LSFO, scaling is prevented by forcing oxidation of calcium sulfite to calcium sulfate by blowing air into the reaction tank (insitu oxidation), or into an additional hold tank (exsitu oxidation).
