FIELD: oil refinery, chemical and petrochemical industries, methods of oil rectification in particular. SUBSTANCE: aim is to increase productivity and output of aim products. Oil rectification method provides for oil heating in heat-exchangers and then - in furnace and its introduction in complex rectification column equipped with side stripping towers, with selection from column top of gasoline fraction, as side fractions - passed through stripping towers - kerosene fraction and diesel fuel fraction and as distillation residual - residual oil during evaporating reactant feeding in column and stripping towers bottom. Flows of heated and unheated in heat-exchangers oil are fed in cross-section of column between output of diesel fuel fractions and introduction of furnace heated oil flow. EFFECT: increased productivity and output of aim products. |
