Process for obtaining aromatic oils with a lower content Polycyclic aromatic compounds useful as 3 processing oils.

摘要

PROCEDURE FOR OBTAINING AROMATIC OILS CONTAINING POLYCYCLIC AROMATIC COMPOUNDS less than 3%, useful as viscosity modifiers RUBBER, FLOW FROM MIXED EXTRACTS OBTAINED IN THE MANUFACTURE OF BASES LUBRICANTES. Said method comprises cooling MIXED FLOW EXTRACTS, PRODUCING COMPONENTS NO polyaromatic insoluble; Let stand TO ACHIEVE SEPARATION OF BASES; Redissolve wholly or partially in a solvent, phase obtained in step LIGHT IDLE; CHILL TO PRODUCE THE SEPARATION OF COMPONENTS NO polyaromatic; And let stand to recover the light phase with a low content of polyaromatic compounds. ADD TO FLOW EXTRACTS MIXED game, a hydrocarbon stream can with a boiling point above 200 (degrees) C START TO REGULATE THE RELATIONSHIP THINNER / SOLUTE AND INCREASE PRODUCTION CAPACITY OF OILS AROMATIC CONTAINING PCA LOWER AL3 %.
