    摘要： Recovering oil and gas from subterranean oil and gas reservoirs using gas injection can serve an additional purpose of capturing and sequestering carbon dioxide. This can be accomplished where the feed gas for the gas injection is, at least in part, carbon dioxide from a carbon dioxide capture and sequestration process. Corrosion of steel in a gas transportation system due to the presence of carbon dioxide and water and oxygen may be prevented or at least mitigated by employing a corrosion inhibitor effective at preventing or mitigating steel corrosion in the presence of oxygen and carbon dioxide. The corrosion inhibitors may incorporate alkyl succinic acids, alkyl succinic anhydrides, and trimer acids.

    摘要： Mitigating or preventing corrosion of metal may be achieved in systems that are alkaline, such as carbon dioxide capture systems. The method may include adding an additive to a system wherein the system is at an alkaline pH; the system has both O2 and CO2 present; or the system is at an alkaline pH and has both O2 and CO2 present. The additive may be selected from the group consisting of: quaternary aromatic amines; quaternary alkyl substituted aromatic amines; and combinations thereof. The corrosion inhibiting properties of the additives may be increased by use of synergistic combinants. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
