Patent ID: 7488863

Claim:
A process for destruction of organic halides in an asphaltic waste, comprising: crushing a solid asphaltic waste containing an organic halide to provide an asphaltic waste containing the organic halide for treatment, the crushing being carried out at a crushing temperature that is below a melting temperature of the solid asphaltic waste; mixing the asphaltic waste with a solvent to produce a waste-solvent mixture; heating the waste-solvent mixture to a dissolving temperature for a dissolving time to produce a heated waste-solvent mixture in which the asphaltic waste is dissolved in the solvent so that the organic halide is released from the asphaltic waste; adding a metallic alkali metal destructive reactant to the heated waste-solvent mixture at a reaction temperature for a reaction time to produce a treated waste-solvent mixture in which the organic halide is substantially all reacted with the destructive reactant to destroy the organic halide; and distilling the treated waste-solvent mixture to separate the solvent from the asphaltic waste to produce a recyclable solvent substantially free of asphaltic waste and reusing the recyclable solvent as the solvent in the mixing of the asphaltic waste with the solvent to produce the waste-solvent mixture.
