Abstract:
Described are an apparatus and a method for recovering styrene monomer using an auxiliary solvent, more particularly an apparatus and a method for recovering styrene monomer through pyrolysis of waste polystyrene capable of improving recovery ratio of styrene monomer using an auxiliary solvent such as steam, preventing repolymerization of pyrolyzed styrene monomer and effectively preventing production of unwanted high molecular weight materials.
