The presence of elemental mercury in wellhead natural gas has been well documented. Mercury-induced corrosion of LNG aluminum alloy cryogenic exchangers has led to many instances of equipment failure, and mercury present in a hydrogen, syngas or hydrocarbon gas stream shortens the useful lives of many precious metal catalysts.

Chemviron has been defining system requirements and supplying HGR activated carbon products for mercury removal to liquid natural gas plants for more than 40 years using an extensive performance database produced from both lab and field studies.

Our products and technologies are proven to be effective, and continue to be the benchmark of performance for liquid natural gas applications under most treatment conditions.

Gas Processing with Activated Carbon
Mercury Removal with HGR®

A large percentage of natural gas reserves contain trace concentrations of mercury. Mercury removal is particularly important in the production of Liquefied Natural Gas (LNG) as the mercury can lead to corrosion of aluminium heat exchangers used in this process. HGR® is the leading technology for the removal of mercury from natural gas.

HGR® is impregnated with sulfur which will react with the mercury and fix it within the pores of the activated carbon. HGR® has numerous references including the Middle East, North Africa, Europe, Asia and the Americas.

For the removal of mercury from liquid hydrocarbons, HGR®-LH can remove up to 22 times more mercury than standard activated carbon.
