Abstract: Elimination of mercury contained in a hydrocarbon feed by: a) feed 1 is mixed with a hydrogen stream 14 and a gaseous fraction 13 originating from c), b) mixture 1a contacted with a catalyst to convert mercury compounds to elemental mercury producing an effluent containing elemental mercury 6, c) effluent containing elemental mercury is cooled to between 20° C. and 80° C., then, at 1.5 MPa and 3.5 MPa and between 20° C. and 80° C., separation 10 of said effluent containing the elemental mercury into a gaseous fraction 11 and a liquid fraction 15, at least a part of said gaseous fraction 11 being recycled to step a), d) fractionation 20 of liquid fraction 15 to produce a gaseous phase 42 and a liquid phase 21, and e) contacting at least a part of gaseous phase 42 with a mercury collection material 43.
