Abstract (en)
[origin: US2017306504A1] Disclosed are methods for inhibiting the corrosion of metal containments such as carbon-steel pipes used in oil recovery processes, the methods comprising adding urine and/or compositions comprising urine to water sources to form corrosion inhibitor compositions, and contacting metal containments with the corrosion inhibitor compositions. The water sources are for example aqueous solutions that are corrosive to metal containments such as carbon-steel pipes. Compositions comprising urine that provide reduced corrosion or corrosion inhibition are also described. Metal containment assemblages comprising corrosion inhibitor compositions and a metal containment are also described.
