Title:
APPARATUS AND METHOD FOR RECOVERING MARKETABLE PRODUCTS FROM SCRAP RUBBER
Document Type and Number:
WIPO Patent Application WO2002026914
Kind Code:
A3
Abstract:
Tire pyrolysis systems and processes are provided which include feeding tire shreds to a pyrolysis vessel (40) and pyrolyzing the shreds in a pyrolysis vessel (40) to produce a pyrolysis gas and carbon black mixture. The pyrolysis gas processed by centrifugally separating entrained particles therefrom, separating the pyrolysis gas into a hydrocarbon condensate and a light vapor, removing entrained hydrocarbon condensate from the light vapor, and purifying and refining the hydrocarbon condensate. The carbon black mixture is processed by pulverizing the mixture to break up all strands and clumps of inorganic solids, cooling the carbon black mixture, separating the gross contaminants from the carbon mixture, and purifying and refining the carbon black. The hydrocarbon condensate is puridied and refined by removing all remaining contaminants, removing any polycyclic aromatics to produce a clear, colorless plasticizer oil. The carbon black is purified and refined by pulverizing it into a powder, removing all remaining particulate contaminants, optionally pelletizing the carbon black, and bagging or packaging it for shipping.
