Abstract: The installation comprises a thermolysis/cracking reactor that is intended for degradation of organic compounds and presents an enclosure (2) including an input for supplying molten liquid matters to be treated and an output (5) for decomposing gases, and a heating unit to carry reagents in the enclosure in a temperature. The reactor includes an agitation unit (6) that is arranged in an interior of the enclosure and movable compared to the enclosure. The heating unit is embarked with the agitation unit, and interdependently moves the agitation unit. The installation comprises a thermolysis/cracking reactor that is intended for degradation of organic compounds and presents an enclosure (2) including an input for supplying molten liquid matters to be treated and an output (5) for decomposing gases, and a heating unit to carry reagents in the enclosure in a temperature. The reactor includes an agitation unit (6) that is arranged in an interior of the enclosure and movable compared to the enclosure. The heating unit is embarked with the agitation unit, and interdependently moves the agitation unit such that the reagents contained in the interior of the enclosure are heated. The installation comprises: a melter ready to dissolve the organic compounds in the molten liquid matter in an upstream of the reactor; a condensation unit that is supplied with gases of decomposition form the output, and condenses the gases of decomposition to obtain oil; a oil collection system for collecting the oil produced by the condensation unit; and a system of destruction of volatile compounds. The agitation unit includes a rotor (60) presenting a drum and heat-conducting blades (62). The drum is integral to an interior volume of the heating unit, and presents protrusions on an external cylindrical wall of the heat-conducting blades. The blades are arranged over a length and a circumference of the drum so as to ensure that transfer of heat from the drum towards the reagents by an intermediate of the blades and agitation of the liquid in the enclosure and a thin film constitution of liquid on the blades and the drum of the rotor during rotation of the rotor. The enclosure is cylindrical, and horizontally oriented, longitudinal, and cylindrical enclosure, and presents longitudinal ends with the input and an output for solid residues distinct from the output for gases decomposition. The reactor includes a convoying unit that is arranged in the interior of the enclosure and ensures the transfer of solid residues from the input towards the output for the solid residues. The convoying unit comprises the rotor whose blades are arranged over the circumference and the length of the rotor so as to ensure the transfer of the solid residues from the input towards the output for solid residues. A part of an internal surface of the enclosure is mirror polished. The heating unit includes electrical resistors and coolant conduits. The external wall of the enclosure presents a thermal isolation unit including an envelope to double the external wall. The axis of the enclosure is tilted compared to a horizontal so that a level of the input is located on a level that is lower than a level of the output for solid residues.
