ABSTRACT:
A process and apparatus for the recovery of hydrocarbons from hydrocarbon containing composite materials, particularly roofing materials including asphalt and solid components to recover asphalt and the solid components. The process includes the steps of: agitating the materials with a solvent, preferably a terpene, to form a hydrocarbon/solvent mixture; heating the hydrocarbon/solvent mixture to vaporize the solvent; recovering the hydrocarbons; and recovering the solvent as a liquid by condensing the solvent vapor. The apparatus includes a composite materials washer for holding the composite materials and a solvent; means for agitating the composite materials washer to dissolve the hydrocarbons in the solvent; and a separator for vaporizing the solvent in the hydrocarbon/solvent mixture and recovering the hydrocarbons.
