ALUMINA GEL / ACTIVATED ALUMINA / IRON OXIDE DESULPHURISATION MASS
Iron Oxide mass is used for the removal of H2S from gas stream. The mass is normally supplied in the form of extrudates and granules dispersed on wood shavings.
Salient Features
- High H2S adsorption.
- Good Mechanical strength.
- Low pressure drop across bed.
