High efficiency recovery process and apparatus for the pyrolysis treatment and halogenation of multi-element waste

摘要

A high efficient recovery process for the treatment of multi-element wastes which comprises the steps of: a) heat treatment of the waste in the presence of a controlled amount of oxygen; b) halogenation of the product of step "a"; and c) separation of the gaseous metal halide products of step "b". An apparatus for carrying out the recovery process comprises a primary heat chamber, a halogenation chamber and a separation unit.
