Claims21
A system for converting waste plastic material to petrochemicals, the system comprising:
- a feed inlet and distributor section;
- a raked film reaction section located below the feed inlet and distributor section;
- and
- a stirred tank reaction section located below the raked film reaction section;
- wherein the feed inlet and distributor section comprises:
- one or more feed inlet pipes configured for receiving a waste plastic material feed stream comprising a molten plastic material;
- a distributor assembly configured for collecting the molten plastic material in a weir and distributing the molten plastic material onto an interior wall of the raked film reaction section;
- and
- a vapor outlet configured for collecting and removing a vapor effluent produced in the raked film reaction section.
