Abstract: The apparatus for thermolysis of waste plastics has a feeding system, a thermolysis reactor, an external circulation loop, and a product collecting system. The collecting and two-step product separation system includes a condenser, a product cooling system, a light fraction receiver with a gaseous product removing system, a crude heavy fraction receiver, and a vacuum evaporator. In the plastic waste thermolysis method, product vapors are removed continuously from the reactor and conducted to the condenser for condensation of vapors to yield a product mixture, which is separated into light oil and crude heavy oil. The light oil is conducted to the light oil receiver and a light oil tank for further processing. The crude heavy oil is pumped to a vacuum evaporator through a heat exchanger for separating into wax and heavy oil for further processing.

Abstract: The invention provides an apparatus and method for thermolysis of waste plastic in which reaction residue and carbonization products are continuously removed. The apparatus includes a feeding system, an extruder, a reactor for thermolysis, a dual agitator housed within the reactor, a trigger system in operative connection with the reactor, a flux heater, and a collecting system in operative connection with the reactor. The reactor for thermolysis has a height at least 1.5 times bigger than a diameter. The trigger system includes a circulation pump and the collecting system has a three-way valve in an external circulation loop. The apparatus is arranged such that the extruder follows the feeding system, the reactor follows the extruder, the trigger system is at a bottom of the reactor, and the flux heater and collecting system follow the reactor.

Abstract: The invention provides an apparatus for thermolysis of waste plastics, particularly polyolefins. The apparatus includes a feeding system, an extruder, a main thermolysis reactor, a dual propeller/mixer housed within the reactor, and a discharging system. The height of the thermolysis reactor is at least 1.5 times bigger than the diameter. The apparatus is arranged such that the extruder follows the plastic feeding system, the thermolysis reactor follows the extruder, and the discharge system follows the thermolysis reactor. The invention also provides a method for using the apparatus for thermolysis of waste plastics. In this method, reaction feedstock, reaction residuals, and reaction products are removed continuously.
