Claims (1)

Способ селективной очистки масляных фракций путем противоточного контактирования сырья, вводимого в среднюю часть экстрактора, с растворителем, вводимым в верхнюю часть экстрактора, в присутствии антирастворителя, подаваемого в нижнюю часть экстрактора, с последующей регенерацией растворителя из рафинатного и экстрактного растворов с получением рафината и экстракта, отличающийся тем, что часть рафината при температуре, не превышающей температуры ввода сырья и не ниже температуры ввода антирастворителя, возвращают в нижнюю часть экстрактора не выше ввода сырья, и часть экстракта при температуре, не превышающей температуры ввода растворителя и не ниже температуры ввода антирастворителя, возвращают в экстрактор между вводами растворителя и рафината.A method for the selective purification of oil fractions by countercurrent contacting of raw materials introduced into the middle part of the extractor with a solvent introduced into the upper part of the extractor in the presence of an anti-solvent fed to the lower part of the extractor, followed by regeneration of the solvent from raffinate and extract solutions to obtain raffinate and extract, characterized in that a portion of the raffinate at a temperature not exceeding the input temperature of the raw material and not lower than the input temperature of the anti-solvent is returned to the lower part of the ex raktora not higher input of raw materials, and part of the extract at a temperature not exceeding the temperature of the solvent entering and below the temperature input antisolvent is recycled to the extractor between the inputs and the solvent raffinate.
