  • Tire liquefying process reactor discharge system and method
    Patent number: 5464503
    Abstract: A discharge system is used with a tire liquefaction process using a reactor. The system includes a receiver receiving unreacted components, including oil coated metal, from the reactor. The unreacted components are moved through a pyrolysis reactor where they are heated to a temperature sufficient to convert the unreacted hydrocarbon components to a liquid and to gas by way of pyrolysis. The liquid and the majority of gas are drawn off from the pyrolysis reactor. Discharge apparatus connected to the pyrolysis reactor converts the remaining gas to a condensate and discharges the metal. The condensate is also removed for further use.
