IRON REDUCER

IR-AS-140RN is a high-performance iron reducer. Ferric and ferrous ions remain in acid solutions during acidizing operations due to the very low pH of acids. When acid travels from surface to formation, it will dissolve iron from equipment, tubulars, scales, and iron minerals in the formation. During spending of the acid, the pH of the acid will go up and can result in the precipitation of iron. Trivalent Iron (Ferric) precipitates at about pH 3, white the divalent Iron (Ferrous) will not precipitate until the acid spent to a pH of 8. To minimize the precipitation of iron, it is better to keep the iron in the ferrous state. It is therefore required to add an iron stabilizer (reducer) in acid systems. IR-AS-140RN is a high-performance iron-reducing agent used in acids to convert Ferric iron into ferrous iron so that it will prevent Ferric hydroxide precipitation.
