Abstract: Dealing with the exhaust gases from aluminium smelters is still an interesting subject for investigation. The amount of H2S in aluminium reduction cells is enough to produce H2S gaze. Immediate removal of the highly toxic H2S gases makes FTP (Fume Treatment Plant) to just deal with fluoric gases such as HF. Due to the capability of nanotubes in adsorbing gases, this study has been conducted to figure out the adsorption of H2S on (8,8) armchair carbon nanotubes (CNTs). Lennaed-Jones potential was used for gasgas and gas-carbon nanotube interactions and the potential parameters for the carbon-gas and carbon-carbon interactions were obtained from the Lorenz-Berthelot combining rules. The study has been done by using the equation state of Virial and finding the second coefficient in Virial equation. Final steps were the inside density, outside density and total density of nanotubes calculation
