Abstract: Methods, systems and designs are provided for removing mercury from crudes. Crude oil is heated to a temperature above 100° C. in a stabilization column for a time sufficient to convert all of the forms of mercury in the oil into the elemental mercury form. The elemental mercury is then stripped from the crude oil by flashing, or preferably by gas stripping with a gas injected at the bottom of the column. Either process transfers the elemental mercury from the oil phase into the gas phase. Elemental mercury can then be removed from the gas phase by methods such as condensation, precipitation, or absorption either alone or in combination.
