Pyrolysis reactor system and method

A system for the pyrolysis of a pyrolysis feedstock comprising:

• a pyrolysis reactor for producing pyrolysis products from the pyrolysis feedstock to be pyrolyzed;
• and
• an eductor condenser unit in fluid communication with the pyrolysis reactor, the eductor condenser unit comprising:
• an eductor assembly having an eductor body that defines a first flow path with a venturi restriction disposed therein for receiving a pressurized coolant fluid and a second flow path for receiving pyrolysis gases from the pyrolysis reactor, the second flow path intersecting the first flow path so that the received pyrolysis gases are combined with the coolant fluid, the eductor body having a discharge to allow the combined coolant fluid and pyrolysis gases to be discharged together from the eductor;
• and
• a mixing chamber in fluid communication with the discharge of the eductor to facilitate mixing of the combined coolant fluid and pyrolysis gases wherein at least a portion of the pyrolysis gases are condensed within the mixing chamber;
• an upstream condenser unit in fluid communication with the pyrolysis reactor for condensing pyrolysis gases from the pyrolysis reactor, and wherein non-condensed pyrolysis gases from the upstream condenser are discharged to and received by the second flow path of the eductor condenser unit, the upstream condenser unit further comprises a condenser inlet clearing assembly to facilitate clearing of pyrolysis oil and/or solids buildup from an inlet of the upstream condenser unit;
• and
• a pressure sensor for monitoring a pressure difference between the inlet of the upstream condenser unit and the internal pressure of the upstream condensing unit;
• and wherein
• the clearing assembly is automated and configured to be actuated upon a selected pressure drop being monitored by the pressure sensor.
