Abstract:
The invention concerns a method (100) for recovering and/or recycling a bituminous product by means of pulsed power, the bituminous product comprising bitumen and elements to be separated, involving the following steps: supplying (101) a reactor (11) inside which at least two electrodes (13) extend with the bituminous product and a liquid medium of which at least one liquid component has Hansen solubility parameters δη, δρ and δd such that the bitumen is at least partially soluble in the liquid medium, the elements to be separated being insoluble, generating (102) a series of electromagnetic pulses between the electrodes (13) in the reactor (11) so as to produce, as a result of the power, the frequency and the switching time of the electromagnetic pulses, at least one shock wave and at least ultraviolet radiation, in such a way as to disperse and dissolve the bitumen in the liquid medium, and to separate the bitumen and the insoluble elements, the liquid medium preventing the reconstitution of the bitumen.
