A series of α,ω-diamines of polyoxyethylene–polyoxypropylene–polyoxyethylene (POE–POP–POE) triblock copolymer was synthesized and experimentally evaluated as dewatering agents for heavy crude oil. A quantitative structure–activity relatio

Although normally the copolymers used to remove water from crude oil have a block structure, two series of random acrylic copolymers were evaluated as petroleum demulsifiers. These acrylic copolyme...

This work includes both experimental and theoretical studies of the wetting property changes of water on a surface of poly(dimethylsiloxane) (PDMS) modified with different amounts of acrylic acid (AA). The default surface properties of PDMS were chan

One series of ionic liquids (IL), [TOA]+ [Y] (where [Y]− = [Cl]−, [HSO4]− or [H2PO4]−), and new ammonium salts, [OCD]+ [Y]− (where [Y] = [HSO4]−, [MeSO3]− or [MePhSO3]−), were evaluated as demulsifying agents for super-heavy crude oil

One of the main problems that petroleum industry must face is the growing difficulty to extract both water and salts present in heavy crude oils. High viscosity, and enormous contents of resins and asphaltenes contribute to stabilize the water drople

A series of copolymers derived from styrene (S), n-butyl acrylate (BuA), and vinyl acetate (VA) monomers were prepared by emulsion polymerization to improve some physical properties of Mexican crude oils (MCOs). Once obtained, the copolymers were cha

This work presents a theoretical study of the effects of different molecular weights of a triblock co-polymer ethylene oxide/propylene oxide/ethylene oxide, bifunctionalized with ethalamine, on the coalescence of water drops imbibed in a crude oil en
