METHOD FOR REMOVING MERCURY FROM LIQUID HYDROCARBON

摘要

PROBLEM TO BE SOLVED: To provide an industrial process for simply and efficiently removing ionic mercury from a liquid hydrocarbon including ionic mercury received in a vessel. SOLUTION: The liquid hydrocarbon including ionic mercury received in a vessel is brought into contact with a sulfur compound represented by the formula (I): M1-S-M2 (wherein M1 and M2 are each H, an alkali metal or an ammonium group) to remove the ionic mercury. In this case, a piping for circulating the liquid hydrocarbon including the ionic mercury by a pump is installed and the sulfur compound represented by the formula (I) is injected into the inlet side or the outlet side of the pump.
