Heavy oil separation method and treatment system thereof

The present invention provides a heavy oil separation method and a treatment system thereof. According to the separation method, an extraction tower with a plurality of filler sections arranged on the upper portion region is used, distributors are arranged between the adjacent filler sections, and a supercritical solvent from a supercritical solvent recovery tower is introduced through the distributors so as to further separate the heavy components in the deasphalted oil phase on the upper portion of the extraction tower. With the separation method of the present invention, the problem that the heavy oil raw material separation effect is not significant during the extraction separation process in the prior art can be effectively solved so as to obtain the target product with characteristics of high yield and excellent property.
