A system for converting waste plastic material to petrochemicals. The system including a feed inlet and distributor zone, a raked film reaction section located below the feed inlet and distributor zone, and a stirred tank reaction section located below the raked film reaction section.

Plastic pyrolysis reactor

A system may include a turbine and a recuperative heat exchanger system. The recuperative heat exchanger system is configured to receive exhaust gases from the turbine. The recuperative heat exchanger system may include a precool section to cool the exhaust gases, a major heating section to receive the cooled the exhaust gases, and a minor heating section to receive the cooled the exhaust gases.

Recuperative heat exchanger system

A heat exchanger system includes a rigid framework. A first heat exchanger may be coupled to a first support structure on a top of the rigid framework. A second heat exchanger may be positioned below the first heat exchanger. The second heat exchanger may be coupled to a second support structure. The second support structure may hang from the rigid framework via a first set of tethers. The first set of tethers may be configured to vertically and horizontally move the second support structure. The vertically and horizontally movement of the second support structure may be based on a thermal expansion of the second heat exchanger.

Heat exchanger hanger system

Process and systems for converting waste plastics include feeding a waste plastic to a melt tank, and in the melt tank, heating the waste plastic to form a molten plastic. The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor. In the pyrolysis reactor, the molten plastic is heated to a pyrolysis temperature, producing a pyrolysis oil product and a liquid pitch product. The pyrolysis oil is then separated into a pyrolysis gas fraction, a light pyrolysis oil fraction, a medium pyrolysis oil fraction, and a heavy pyrolysis oil fraction.
