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.
