ABSTRACT:
A method for processing heavy crude oils comprising a) atmospheric distillation of a heavy crude oil having a high content of metals, asphaltenes and sulfur; b) solvent extraction of the atmospheric distillation residue to obtain an extract with characteristics equivalent to those which an atmospheric residue derived from light crude oil and a raffinate fraction, solid at ambient conditions, in which are concentrated the asphaltenes, metals and sulfur present in the original crude oil; c) vacuum distillation of the deasphalted extract, obtaining a light fraction or gas oils with characteristics adequate to be subjected to a secondary conversion process, plus a bottoms fraction or vacuum residue; d) treatment of the vacuum gas oils in a conversion stage and e) subjecting the bottoms of raffinate from the extraction stage to a metallurgical process, in admixture with cokeable coal and coke fines to production of metallurgical coke.
