METHOD FOR REMOVING HALOGEN IN WASTE SYNTHETIC RESINS

摘要

PROBLEM TO BE SOLVED: To provide a method for removing a halogen in a waste synthetic resin capable of preventing complication of a process and a rise in an energy cost and reducing a halogen. SOLUTION: This method for removing a halogen of a waste synthetic resin comprises a first-stage dehalogenating process (A) for heating and dehalogenating a halogen-containing waste synthetic resin, a granulation process (B) for flowing a melt obtained by heating down and blowing an inert gas on the flow to give a granule and a second-stage dehalogenating process (C) for cleaning a granule.
