Abstract
The present invention relates to a method for the physical separation of solids and asphaltenes with a conversion degree higher than or equal to 90%, present in refinery purge streams. Said method provides for heating a refinery purge stream to a temperature higher than or equal to 185° C. and not exceeding 220° C. and, subsequently, subjecting said heated purge to sedimentation by progressively lowering the temperature in a controlled manner to a minimum temperature of 100° C., without stirring the purge, so as to form a light phase and a heavy phase defined in relation to the density.
