FIELD: oil processing industry; methods and devices of the fractionation of the hydrocarbon raw.
SUBSTANCE: the invention is pertaining to the oil the oil products production process and may be used at the installations with the atmospheric and vacuum columns intended for fractionation distillation of the petroleum. At realization of the method act upon the hydrocarbon raw by the electromagnetic oscillations using the preliminary and main electromagnetic excitation. The preliminary action on the hydrocarbon raw is exercised in the working tanks or in the pipeline before the kilns of heating, and the main action is exercised in the rectification tower itself due to its resonant excitation. In the installation for realization of the method the source of the preliminary excitation is made in the form of the electromagnetic emitter with the preset frequency of oscillation, and the rectification tower after its resonance activation serves as the main exciter of the hydrocarbon raw under condition of provision of its operation in the self-oscillation mode. The formula for calculation of the oscillation frequency as the variable includes the temperature of the separation of the appropriate fraction. The technical result of the invention is the increased output of the light oils at reduction of the power inputs.
EFFECT: the invention ensures the increased output of the light oils at reduction of the power inputs.
