Abstract

A discharge system is used with a tire liquefaction process using a reactor (4). The system includes a receiver (8) receiving unreacted components, including oil coated metal, from the reactor (4). The unreacted components are moved through a pyrolysis reactor (38) 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 (38). Discharge apparatus (45) connected to the pyrolysis reactor (38) converts the remaining gas to a condensate and discharges the metal. The condensate is also removed for further use.

Claims

AMENDED CLAIMS[received by the International Bureau on 12 April 1995 (12.04.95); original claims 2-5, 7, 10 and 11 cancelled; original claims 1, 6, 8, 9, 12 and 13 amended; original claim 14 unchanged (4 pages)]

1. A discharge system for a tire liquefying process reacting tires and oil using a process reactor, comprising: a first vertical conduit for receiving unreacted hydrocarbons and metal components of the tires from a tire liquefying process reactor; a pyrolysis reactor having an auger screw means for moving the unreacted components therethrough and a heating means for heating the unreacted components to a temperature sufficient to convert the unreacted hydrocarbon components to a liquid and to a gas by way of pyrolysis; said first vertical conduit allowing the unreacted hydrocarbons and metal components to pass through to the pyrolysis reactor; said pyrolysis reactor set at a slight angle to the horizon sufficient to allow fluid to flow due to gravity and connected to said first vertical conduit; a second vertical conduit connected to the pyrolysis reactor at the opposite end of the pyrolysis reactor from the first vertical conduit for receiving components from the pyrolysis reactor and discharging metal components from the system; a means for drawing off liquid from the pyrolysis reactor located at the end of the pyrolysis reactor near the first vertical conduit; a means for drawing off most of the gas produced in the pyrolysis reactor located at the end of the pyrolysis reactor near the second vertical conduit;

-9- cooling coils wrapped around a portion of the second vertical conduit so as to create a cool surface on that portion of the second vertical conduit for gas from the pyrolysis reactor which has entered the second vertical conduit to condense on to form a condensate; and a flared vent means for removing condensate from the second vertical conduit located in a portion of the second vertical conduit below the cooling jacket.

2. Cancelled.

3. Cancelled.

4. Cancelled.

5. Cancelled.

6. A system as described in Claim 1 in which the flared vent means further includes: enclosure means surrounding that portion of the second vertical conduit that is vented by the flared vent means for gathering the condensate that has passed through the flared vent means; and tank means connected to the enclosure means for accumulating the condensate that has passed through the flared vent means.

7. Cancelled.

8. A system as described in Claim 1 in which the heating means is located on the outside of the pyrolysis reactor for creating heat so as to pyrolyze the unreacted hydrocarbon components passing through the pyrolysis reactor.

9. A discharge method associated with a tire liquefying process using a process reactor, comprising the steps of: receiving unreacted hydrocarbons and metal components of tires from a tire liquefying process reactor; moving the unreacted components with an auger screw means; heating the moving unreacted components to a temperature sufficient to convert the unreacted hydrocarbon components to a liquid and a gas by pyrolysis; drawing off the liquid; drawing off most of the gas; cooling the remaining gas after pyrolysis that is not drawn off to a condensate in a vertical conduit; drawing off the condensate from the vertical conduit; and discharging unreacted metal components through the vertical conduit that is used to cool and condense the remaining gas.

10. Cancelled.

11. Cancelled.

12. A method as described in Claim 9 in which the cooling step includes using a cooling jacket of tubing containing a cooling liquid, said tubing wrapped around a portion of the vertical conduit so as to create a cool surface on that portion of the vertical conduit for the gas to condense on.

-11-

13. A method as described in Claim 9 in which the condensate drawing off step includes: venting the vertical conduit with flared openings in its side located below the cooling portion; and accumulating the condensate that has passed through the vented openings.

14. A method as described in Claim 13 further comprising the step of removing the liquid resulting from the pyrolysis of the unreacted components.

STATEMENT UNDER ARTICLE 19

This statement accompanies the Amendment under Article 19.

Claim 1 has been amended to incorporate the limitations of claims 2-5, which have been cancelled. Claims 6 and 8 have been amended to more precisely define the invention, and are now dependent on claim 1. Claim 7 has been cancelled.

Claim 9 has been amended to incorporate the limitations of claims 10 and 11, which have been cancelled.

Claims 12 and 13 have been amended to more precisely define the invention, and are each dependent on claim 9. Claim 14 is unchanged.

All amendments are consistent with the amendments made to the claims in the priority U.S. patent application

Serial No. 08/142,014 which was allowed on September 9, 1994 and upon which this PCT application is based. No new matter has been added.
