Abstract: The present disclosure provides methods and compositions for inhibiting corrosion of metallic surfaces and dissolving iron sulfide deposits in aqueous systems. A method may include adding a composition to the aqueous medium. The composition may include malic acid or a salt thereof. The composition may optionally include an organic solvent and/or a corrosion inhibitor.

Abstract: The present disclosure provides methods and compositions for dissolving deposits and inhibiting corrosion of metallic surfaces in aqueous systems. A method may include adding a composition to the aqueous medium. The composition may include a polycarboxylate polymer and a nitrogen-containing compound. The composition may optionally include a solvent and/or an additive. The compositions and methods may be used for inhibiting corrosion of metallic surfaces and dissolving typical insoluble inorganic salts encountered in the oil and gas, recovery, water, and processing industries.

Abstract: The present disclosure relates to various testing methods that can be applied to oils, such as pyrolysis oils. Different testing methods can be used to determine the oxidative stability of an oil. The testing methods may also be used to differentiate between various oils and to determine the effectiveness of various antioxidants on the oxidative stability of an oil.
