Abstract: A process is provided including subjecting a raw C5 stream containing C5 diolefins to extractive distillation to form C5 diolefins and a raffinate stream. The process includes subjecting the raffinate stream to dehydrogenation to form additional C5 diolefins, which are recycled to the extractive distillation. Another process includes modifying a C5 diolefin extractive distillation unit by forming a recycle loop with a C5 olefin dehydrogenation reactor. A system is provided that includes a C5 diolefin extractive distillation unit and a C5 olefin dehydrogenation reactor that are arranged in a recycle loop. A process is provided that includes subjecting a raffinate stream containing C5 olefins from an extractive distillation unit to dehydrogenation to form C5 diolefins.

Abstract: 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.
