Abstract
A process and a system for continuously depolymerizing plastic is disclosed. The system may comprise a mixer for producing a heterogeneous reaction mixture comprising plastic particles and a solvent, a pump for transmitting the reaction mixture at a particle speed sufficient to maintain the plastic particles in suspension in the solvent, a heating apparatus for heating the reaction mixture to its reaction temperature, a hold tube for maintaining the reaction mixture at or above the reaction temperature to facilitate conversion into a homogeneous reaction solution, and a settling tank to allow a solid reaction product to precipitate from the homogeneous reaction solution once cooled.
