CONTINUOUS REACTOR FOR THERMAL DEGRADATION OF POLYSTYRENE AND METHOD FOR RECOVERY OF STYRENE USING IT

摘要

PURPOSE: An apparatus for recovering a styrene monomer is provided to prevent the yield of a styrene monomer from being lowered in a long time operation by consecutively discharging residues and to maximized the yield of styrene monomer according to use of twin screw pyrolysis reactor. CONSTITUTION: An apparatus for recovering a styrene monomer includes: a pyrolysis reactor(1) causing the melting and pyrolysis by receiving waste polystyrene; a steam collector(4) for collecting steam vapor created in the pyrolysis reactor; a heat exchanger(5) by liquefying the steam vapor collected in the steam collector and converting into oil; an oil reservoir(7) storing the oil liquefied in the heat exchanger; and a residue drain part(3) for discharging the residue generated after pyrolysis.
