Abstract:
A method for recovering and recycling hydrocarbon residue from a petroleum material, the method consisting essentially of: providing the hydrocarbon residue in a first vessel, wherein the hydrocarbon residue is in the form of solid waxy material; heating a sufficient amount of an organic solvent in a second vessel for an effective period of time to reach a temperature in the range of from 130 degrees F. to about 200 degrees F.; 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 a temperature in the range of from about 130 degrees F. to about 200 degrees F. 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.
