Abstract

Results of a study of the counterflow five-stage extraction of light visbreaker gasoil with N-methylpyrrolidone and phenol are reported. To preclude formation of azeotropes, gasoil was preliminarily separated into light and heavy fractions. Phenol with 10% water was used as a solvent for the light fraction, and N-methylpyrrolidone, for the heavy fraction. It is shown that the raffinates obtained can be used to produce diesel fuel of K-5 ecological class according to the technical regulations of the Customs Union by subsequent hydrotreatment at moderate pressures.
