CASE 3391 "CONTINUOUS PROCESS FOR DEASPHALTING AND DEMETALLATING A RESIDUE FROM CRUDE OIL DISTILLATION" Abstract A continuous process for deasphalting and demetallating a residue from crude oil distillation, by means o-f dimethyl carbonate as extraction solvent, comprises: - mixing a residue from crude oil distillation with a recycled liquid stream containing oil and dimethyl carbonate, in order to produce a homogeneous solution; - cooling said homogeneous solution and separating a refined light, liquid, phase; an extracted middle phase; and a heavy phase containing asphaltenes; - recovering a primary, deasphalted/demetallated oil from said light phase; - partially recycling said middle phase to the mixing step, and recovering a secondary deasphalted oil from the residual fraction; - recovering asphaltenes from said heavy phase.
