<p>A method for removing the mercury in an ionic state from a liquid hydrocarbon, characterized in that it comprises circulating the liquid hydrocarbon containing the mercury in an ionic state held in a vessel having a circulation means to the vessel and, simultaneously, injecting a sulfur compound represented by the general formula (I): M1-S-M2 - - - (I) , wherein each of M?1 and M2¿ represents a hydrogen atom, an alkali metal or an ammonium group, to the suction side and/or the delivery side of the circulation means, to thereby contact the liquid hydrocarbon containing the mercury in an ionic state with the sulfur compound with good efficiency. The method allows the mercury in an ionic state to be removed from a liquid hydrocarbon with ease and good efficiency.</p> |
