Abstract
The present invention describes a process for heating the reboiler of the propane/propylene separation column situated downstream of an FCC unit and fed with the Ccut from said FCC unit, a process consisting of heating the water in a hot water circuit by means of one or more process fluids originating from units placed upstream and/or downstream of the FCC unit and called hot fluids, one of these fluids being constituted by the overhead vapours from the fractionation column connected to the mild hydrocracking unit.
