FIELD: petrochemical industry; methods of oil and fuels desulfurization.
SUBSTANCE: the invention is pertaining to the field of the oil and fuels desulfurization by ultrasound action on them. The method of the continuous removal of sulfides from liquid mineral fuel provides for mixing of the fuel, water medium and the dialkyl ether having the boiling point at the normal pressure of 25°C or above, and having the following formula R1OR2, in which R1 and R2 are the separate univalent alkyl groups, and the total number of carbon atoms in R1 and R2 is from 3 up to 7, with formation of the multiphase reaction medium. The multiphase reaction medium is passing through the ultrasonic chamber in the continuous running mode, in which the ultrasound acts on the multiphase reaction medium during the time sufficient to stimulate the transformation of the sulfides in the sulfides-containing mineral fuel into sulfones. The outgoing from the ultrasonic chamber multiphase reaction medium is spontaneously laminated into the water and organic phases. The organic phase is separated from the water phase in the form of the mineral fuel with the removed sulfides. The invention allows to effectively decrease the contents of sulfur in the source raw.
EFFECT: the invention ensures the effective reduction of the contents of sulfur in the source raw.
