A Mercury Removal Unit (MRU) is a fixed-bed adsorption process that removes elemental mercury and mercury compounds from natural gas, condensate, and NGL streams prior to cryogenic processing, liquefaction, or fractionation. Mercury is a naturally occurring trace contaminant in hydrocarbons produced from certain geological formations, present at concentrations ranging from below 1 ng/Nm³ to several thousand ng/Nm³ depending on the field.
