NOVELTY - Rubber is heated and vaporized in an atmosphere having less than 6% of oxygen at 340-510 degrees C and negative pressure. The vaporized rubber has several hydrocarbon constituents (HS), and is sprayed with oil having boiling point more than 175 degrees C. Remaining portion of vaporized rubber is condensed such that light oils in HS are liquefied and separated from non-condensing hydrocarbon gases.    USE - For treating waste rubber and producing components used as fuel.    ADVANTAGE - The method is economical, and enables to obtain a clean product efficiently. The method eliminates the need for expensive filtration methods.    DETAILED DESCRIPTION - Rubber is heated using radiant units in an atmosphere having less than 6% of oxygen gas at 340-510 degrees C and a negative pressure such that the rubber is vaporized. The vaporized rubber has several hydrocarbon constituents. The vaporized rubber is sprayed with an oil having a boiling point more than 175 degrees C using a venturi separator such that the oil binds to heavy oil in the hydrocarbon constituents. Remaining portion of the vaporized rubber is condensed such that light oils in the hydrocarbon constituents are liquefied and separated from non-condensing hydrocarbon gases.    An INDEPENDENT CLAIM is included for apparatus (10) for treating waste rubber. The apparatus comprises a furnace having nitrogen gas, a blower in fluid communication with the furnace such that the interior of the furnace has an atmospheric pressure of -2 to -8 inches of water, a venturi separator in fluid communication with the furnace, a heavy oil tank in fluid communication with the venturi separator and a condenser fluidly coupled to the venturi separator. The venturi separator has several nozzles which horizontally spray the vaporized rubber with the oil. The heavy oil binds to the oil in the venturi separator, and is collected in the heavy oil tank. The light oil having boiling point of 36-175 degrees C and non-condensing hydrocarbon gases having boiling point less than 36 degrees C passes through the heavy oil tank and enters into the condenser. The remaining portion of the vaporized rubber is drawn through the condenser such that the light oils are liquefied by cooling the remaining portion at less than 30 degrees C. The non-condensing hydrocarbon gas are drawn through the blower.    DESCRIPTION OF DRAWING(S) - The figure shows the schematic view of the waste rubber treatment method and the apparatus.    apparatus (10)
