A process is provided including subjecting a raw Cstream containing Cdiolefins to extractive distillation to form Cdiolefins and a raffinate stream. The process includes subjecting the raffinate stream to dehydrogenation to form additional Cdiolefins, which are recycled to the extractive distillation. Another process includes modifying a Cdiolefin extractive distillation unit by forming a recycle loop with a Colefin dehydrogenation reactor. A system is provided that includes a Cdiolefin extractive distillation unit and a Colefin dehydrogenation reactor that are arranged in a recycle loop. A process is provided that includes subjecting a raffinate stream containing Colefins from an extractive distillation unit to dehydrogenation to form Cdiolefins.

Upgrading a C5 olefin stream

A styrene monomer reclamation process and system is described. The styrene monomer reclamation process includes providing a waste plastic. The waste plastic includes styrenic polymers. The waste plastic is formed into polymer particles. At least a portion of the polymer particles are dissolved in a solvent to form a polymer stream. The dissolved polymer particles are depolymerized to form a styrene monomer stream.
