Mercury present in natural gas can corrode aluminum cryogenic heat exchangers, poison catalysts, and create safety and environmental risks. A sulfur-impregnated granular activated carbon technology captures elemental and organic mercury through chemisorption, where mercury binds to sulfur within the carbon’s pore structure to form stable mercury sulfide. The material provides high adsorption capacity and long bed life when installed in properly designed adsorption vessels. Performance depends on factors such as moisture, pressure, temperature, and gas composition. The technology has been deployed globally for decades and remains a widely used solution for protecting LNG infrastructure and gas processing equipment from mercury contamination.
