METHOD AND APPARATUS FOR REMOVING CHLORINE FROM HEAT DECOMPOSITION PRODUCT OF RESIN-CONTAINING WASTE

摘要

PROBLEM TO BE SOLVED: To provide a method, and the like, for effectively removing chlorine from the heat decomposition product of a resin-containing waste.

SOLUTION: The method for removing chlorine from the heat decomposition product of the resin-containing waste comprises mixing an oily heat decomposition product formed from the heat decomposition of the resin-containing waste and being in a liquid state with hot washing water to transfer chlorine components such as inorganic chlorine and inorganic chlorides to the water phase; removing the water phase from the system; and recovering the liquid decomposition product in an oil phase left after removing the water phase. Desirably, the feed systems for the heat decomposition product and for the hot washing water are kept at 150-200°C and at 7-20 atm., to mix the former with the latter while the former is kept in a liquid state.
