Abstract: The present invention generally relates to compositions and methods for inhibiting corrosion at a surface in the production, transportation, storage, and separation of crude oil and natural gas.

Abstract: Compounds, compositions and methods are provided for inhibiting corrosion at a surface in the production, transportation, storage, and separation of fluids such as crude oil and natural gas, the compounds having the formula: wherein: Each R1 is independently —CH2OH and —C(O)OH; R2 is Each R3 is independently hydrogen or R5, or both R3 together form a ring via a linker Each R4 is independently hydrogen or R5; R5 is —CH2SC2H4R1; and n is an integer from 0 to 3.

Abstract: Disclosed herein are sulfur-functional tall oil compositions, referred to herein as S-TO compositions. The S-TO is a sulfur-functional tall oil fatty amide composition, or sulfur-functional tall oil phosphate ester composition. Also disclosed herein are S-TO concentrates, which are stable and do not degrade to form H2S under standard storage conditions for a period of 1 day to 5 years. Also disclosed herein are treated water sources and treated metal containments including one or more S-TO compositions. The S-TO compositions inhibit corrosion of a metal containments contacted with one or more water sources, wherein the one or more water sources comprise one or more corrodents. The S-TO compositions are as effective or more effective at inhibiting corrosion than conventional sulfur-based corrosion inhibitors when compared on a weight basis.

Abstract: Disclosed herein are phosphoester anticorrosion compositions comprising an adduct of an alkylphenol ethoxylate phosphate ester with 1,3,5,7-tetraazaadamantane. The adducts are storage stable neat or in a solvent. The adducts are suitably added at about 0.5 ppm to 500 ppm by weight or by volume to a water source comprising one or more corrodents to inhibit corrosion of metal surfaces contacting the water source. The phosphoester anticorrosion compositions are as effective or more effective at inhibiting corrosion than conventional sulfur-based corrosion inhibitors when compared on a weight or volume basis.

Abstract: Disclosed herein are sulfur-functional corrosion inhibitors that are adducts of a cyclic anhydride with 2-mercaptoethanol. Concentrates of the sulfur-functional corrosion inhibitors do not degrade to form H2S under standard storage conditions for a period of up to 5 years. Also disclosed herein are treated water sources and treated metal containments including one or more sulfur-functional corrosion inhibitors. The sulfur-functional corrosion inhibitors inhibit corrosion of metal containments contacted with one or more water sources, wherein the one or more water sources comprise one or more corrodents. The sulfur-functional corrosion inhibitors are as effective or more effective at inhibiting corrosion than conventional sulfur-based corrosion inhibitors when compared on a weight or a volume basis.
