FIELD: crude oil treatment. SUBSTANCE: acidity and corrosion activity of crude oil are reduced by adding effective amount of solid metal-containing compound selected from group including oxides, hydroxides, hydroxide hydrates of IA and IIA-group metals in presence of small amount of water. EFFECT: eliminated corrosive activity, decreased content of acid groups, and reduced oil-water emulsion formation. 31 cl, 3 dwg
