Mercury removal apparatus for liquid hydrocarbon

摘要

A mercury removal apparatus for a liquid hydrocarbon includes a conversion device which converts a mercury component in a raw liquid hydrocarbon into elemental mercury to obtain a first liquid hydrocarbon containing the elemental mercury. The apparatus also includes a first stripping device which brings the first liquid hydrocarbon into counter-current contact with a first stripping gas, thereby transferring the elemental mercury in the first liquid hydrocarbon to the first stripping gas to obtain (i) a second liquid hydrocarbon in which the amount of the elemental mercury decreases and (ii) a first gaseous hydrocarbon containing the elemental mercury.
