Abstract: The present disclosure relates to demulsifier compositions and methods of resolving emulsions using the compositions. The demulsifiers include modified hydroxy-succinimide copolymers. For example, the demulsifiers may include ethoxylated or propoxylated hydroxy-succinimide copolymers. The demulsifier compositions are useful for resolving oil-in-water, water-in-oil, and complex emulsions of water and oil.

Abstract: The present disclosure provides methods and compositions for dissolving iron sulfide deposits in aqueous systems. A method may include adding a composition to the aqueous medium. The composition may include a polycarboxylate polymer and/or a salt thereof. The composition may optionally include a solvent and/or an additive. The compositions and methods may be used for dissolving typical insoluble inorganic salts encountered in the oil and gas, recovery, water, and processing industries.

Abstract: The present disclosure provides compositions and method for controlling fouling in a process for cleaning a hydrocarbon gas. The methods may include adding an effective amount of a composition to a conduit including the hydrocarbon gas. The composition includes, for example, various components, additives, and/or solvents. The compositions and methods may also be used for controlling fouling of equipment used during a process for cleaning and compressing a hydrocarbon gas. The equipment may be selected from, for example, a slug catcher, a scrubber, a suction drum, a compressor, and any combination thereof.

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.

Abstract: The present disclosure relates to methods and compositions for reducing fouling by natural and synthetic foulants that tend to precipitate during hydrocarbon collecting, processing, transporting, and storing. The method includes applying a composition to a hydrocarbon containing the foulant. The composition includes an effective amount of a reaction product of an α-olefin/maleic anhydride copolymer and an amino-hydroxy compound. The foulants may include wax and asphaltenes, for example.
