Abstract

The depolymerization method comprises the successive steps of pyrolizing a feed material containing polymer in a pyrolysis reactor so as to generate a hot gas stream, removing solid and liquid impurities from the gas stream in a separator and condensing the monomer contained in the gas stream in a condenser.

Cold monomer in liquid state is injected into the transfer column, the internals being configured such that the cold monomer flows downwardly inside the transfer column by gravity, heavy contaminants contained in the gas stream condense in liquid state on the internals and flow back down by gravity towards the bottom of the transfer column and into the separator.
