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, tubular, 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.

Features

IR-AS-140RN is an iron-reducing agent used in both fresh and spent acids to keep iron in solution instead of precipitating. It can be used for most applicable stimulation fluid systems at various well conditions. Ferrous iron will not form iron hydroxides until pH of 8. As we know, pH of most spent acids will not be more than pH of 6. Therefore, if the Ferric iron is converted into Ferrous iron, the chance of forming ferric hydroxide precipitation will be dramatically reduced.

IR-AS-140RN is a high-performance iron-reducing agent, which will react with ferric iron in acids and convert it in ferrous iron.

IR-AS-140RN is compatible with most additives in stimulation fluid systems.
