FIELD: oil and gas industry.
SUBSTANCE: task is settled by extraction of nitrogen-containing compounds from hydrocarbon phase into ion fluid (process solution). Process solution represents ion fluid, for example, on the base of alkilimidazol cation and tetrafluoroborate anion or chloride, that contains diluted compounds of transition metals selected from the group including complexes of cobalt (II) and cuprum (I) with 4,5- dicarboxyphtalocianin. Method includes further separation of hydrocarbon fracture from ion fluid and electrochemical regeneration of ion fluid. Ion fluid regeneration is done by electrochemical oxidation of nitrogen-containing compounds.
EFFECT: improvement of hydrocarbon raw materials quality.
