Patent ID: 10808165

Abstract:
Disclosed are inhibitor/cleaner compositions comprising alkyldiphenyloxide disulfonates, and methods of inhibiting corrosion of and removing schmoo from metal containments in contact with corrosive water sources. Also disclosed are metal containment assemblages comprising inhibitor/cleaner compositions and metal containment therefore. The alkyldiphenyloxide disulfonates are soluble or substantially soluble in the water sources and inhibit corrosion of the metal containments by the water sources containing corrodents. The alkyldiphenyloxide disulfonates also remove schmoo from the metal containments. The inhibitor/cleaners of the invention are useful for addition to produced waters and other corrosive water sources resulting from enhanced oil recovery operations. The inhibitor/cleaners inhibit corrosion of tanks, devices, and other metal containments such as carbon steel pipes which come into contact with produced waters from the oil recovery operations, while also providing schmoo reduction and removal from the metal containments. The inhibitor cleaners are also useful for addition to other corrosive aqueous fluids to inhibit corrosion of metal containments with which the aqueous fluids come into contact, such as corrosive aqueous discharge from mines and other industrial operations such as paper-making.
