Abstract: It has been discovered that solid contaminants in a mixture of a hydrocarbon phase and an aqueous phase may be retained in the hydrocarbon phase by introducing to the mixture an effective amount of an oil-wetting additive to retain at least a portion of the solid contaminants in the hydrocarbon phase as contrasted with an aqueous phase. The oil-wetting additive can be a surface-active additive including, but is not necessarily limited to, drilling fluid additives, surfactants, antifoulants, nanoparticles and combinations thereof.

Abstract: It has been discovered that nanoparticles and/or functionalized polymers are effective in removing metal contaminants from a hydrocarbon phase into an aqueous phase. In particular, the nanoparticles and/or functionalized polymers can remove iron contaminants from crude oil into an aqueous phase in a refinery desalter. Suitable nanoparticles can include graphene oxide and/or titanium dioxide. Suitable functionalized polymers include iodododecane-functionalized vinylpyrrolidone/vinylimidazole copolymers, sulfonated-functionalized vinylpyrrolidone/vinylimidazole copolymers, sulfonated polyether ether ketones, imidazole polymers, imidazole copolymers, and/or 3-(1-pyridino)-1-propanesulfonate.

Abstract: A process of manufacturing a free-flowing solid encapsulated drag reducing additive comprises: forming a solid drag reducing additive from one or more C5-20 olefin monomers; dispersing the solid drag reducing additive in a liquid medium to form a dispersion, the liquid medium comprising an encapsulant and a non-solvent; grinding the solid drag reducing additive in the liquid medium under non-cryogenic grinding conditions to form an encapsulated drag reducing additive in a particulate form; and removing the non-solvent by a drying technique including spray drying, flash drying, or rotating disc drying to form the free-flowing solid encapsulated drag reducing additive.

Abstract: A well treatment material for introduction into a subterranean formation is provided. The well treatment material can include a biocide collected onto a sorbent. The biocide can be capable of being desorbed at a generally constant rate over an extended period of time into the subterranean formation. The biocide can be an oxidizing biocide or a non-oxidizing biocide. The sorbent material can include one or more of an absorbent material and an adsorbent material. The biocide can be chlorine dioxide. The sorbent can be one or more of silica gel and graphite.

Abstract: Systems and methods for ion exchange regeneration for resins onsite at an industrial facility are disclosed. The resins can be boron selective resins and the systems and methods can utilize onsite regeneration, recycling of certain effluent streams, and/or treated water as a main water source for regeneration.
