Abstract

The present invention provides for a method for recovering and recycling a hydrocarbon residue from a petroleum material such as crude oil, where the hydrocarbon residue is a waxy solid material. The method comprises providing the hydrocarbon residue in a first vessel; heating a sufficient amount of an organic solvent in a second vessel at an effective temperature for an effective period of time; removing the hydrocarbon residue from the first vessel and adding the hydrocarbon residue to the heated solvent in the second vessel; simultaneously mixing and heating the hydrocarbon residue and the solvent in the second vessel at an effective temperature for an effective period of time to cause a reaction between the hydrocarbon residue and the solvent to produce a liquefied hydrocarbon residue product; pumping the liquefied hydrocarbon residue product out of the second vessel and into a third vessel; and, recycling the liquefied hydrocarbon residue into a usable oil refinery product.
