Abstract

Procedimento per la deasfaltazione e la demetallazione di residui di distillazione sotto vuoto del petrolio mediante dimetilcarbonato (DMC) in presenza di una sovrapressione di anidre carbonica (CO2), comprendente:- la miscelazione di un residuo di distillazione sotto vuoto con dimetilcarbonato (DMC), sotto pressione di CO2, nelle condizioni di temperatura e pressione tali di mantenere il DMC allo stato prevalentemente liquido, e formando una soluzione omogenea con gli oli deasfaltati:- il raffreddamento dell'interno sistema fino ad una temperatura tale dar luogo a tre fasi:- lo sfilato successivo del gas a tale temperatura;- il recupero di un olio primario deasfaltato e parzialmente demetallato dalla fase leggera;- il recupero di un olio secondario deasfaltato e parzialmente demetallato dalla fase intermedia;- il recupero del DMC utilizzato per il suo eventuale riutilizzo.
