Abstract

Un proceso para desasfaltizar y desmetalizar residuos de la destilación al vacío del petróleo usando dimetilcarbonato (DMC) en la presencia de una sobrepresión de dióxido de carbono CO2 que comprende: mezclar un residuo de la destilación al vacío con dimetilcarbonato (DMC) bajo una presión de CO2, a condiciones de temperatura y presión tales como para mantener el DMC en un estado prevalentemente líquido y formar una solución homogénea con los aceites desasfaltados; enfriar todo el sistema a una temperatura, tal como para formar tres fases; luego ventilar el gas a esta temperatura; recuperar un aceite primario desasfaltado y parcialmente desmetalizado a partir de la fase ligera; recuperar un aceite secundario desasfaltado y parcialmente desmetalizado de la fase intermedia; -recuperar el DMC usado para su posible reuso.
