5 METHOD FOR THE ELIMINATION OF MERCURY FROM A FEEDSTOCK DOWNSTREAM OF A FRACTIONATION UNIT *** ** ** Process for the elimination of mercury contained in a heavy hydrocarbon-containing 15 feedstock downstream of a main fractionation unit, a process in which: a) the non-elemental mercury contained in the compounds of said feedstock is transformed to elemental mercury; b) a fractionation of said hydrocarbon-containing feedstock is carried out in a fractionation unit in order to produce a top effluent comprising elemental mercury; 20 c) the top effluent obtained in stage b) is brought into contact with a mercury capture material contained in a unit for the capture of mercury, in order to obtain an effluent that is at least partially de-mercurized.
