Method and apparatus for removing hydrocarbons from discarded tires by pyrolysis.

摘要

Method and apparatus for removing hydrocarbons from discarded tires by pyrolysis. Tire fragments are conveyed through a reactor vessel (32 min ) and indirectly heated by means of a hollow flight screw conveyor. The heated vapors effluent from the reactor vessel (32 min ) are cooled in a first stage condenser (402, 418; 500) to a predetermined temperature. An uncondensed part of the vapors is cooled in a second stage condenser (404, 420; 505) to a lower temperature than in the first stage condenser (402, 418; 500).
