Mercury Removal

Mercury is often present in low concentrations in natural gas, synthesis gas and petrochemical and refinery feedstocks. Mercury is often removed from these gases to comply with environmental and occupational health regulations. Mercury removal from natural gas is critical to prevent corrosion in aluminum heat exchangers used in the production of Liquefied Natural Gas (LNG).

SulfaTrap™-M series mercury removal sorbents offer a cost-effective solution to remove mercury, arsenic, and selenium from liquids and gases. SulfaTrap™-M1 is a physical sorbent that removes elemental, oxidized, and organic forms of mercury to less than 0.01 µg/m3. The sorbent works well with moisture and sulfur compounds present. SulfaTrap™-M2 removes mercury and other metals such as arsenic and selenium. The sorbent works at temperatures up to 300°C to reduce the total metal content to parts per billion levels. The sorbents consist of a high surface area support material grafted with surface function groups to selectively remove mercury and other trace metals.
