Raw natural gas contains hydrogen sulfide (H2S), mercaptans, traces of mercury and other impurities. While H2S and mercaptans are responsible for offensive odour, mercury can lead to corrosion of heat exchangers in downstream operations. In order to purify the natural gas, adsorption using activated carbon is the leading technology.

SpaceBlack Adsorbents provides customized grades of granular and pelletized activated carbon derived from coconut shell charcoal and coal suitable for sweetening of natural gas.
