| Purification of process gas This process is normally used for the removal of O2, H2, CO or hydrocarbons from process gases. However, with this special process for instance also CO2 or methanol can be removed. Catalytic Fine purification of process gases with noble metal catalysts, e.g. removal of O2, H2, CO, KWST hydrocarbons. Normal inlet concentration 0.01...2 %, Residual content less than 1 ppmv Gas capacity up to 30,000 Nm3/h, Operating pressure 1...250 bar Chemisorption Fine purification of process gases with a copper contact, e.g. removal of O2, H2 or CO. The purification takes place by oxidation or reduction of the copper contact, i.e. in the purified process gas no reaction gas is contained. Residual content of O2 and H2 in the purified gas less than 1 ppmv. Others Removal of contaminations by adsorption with molecular sieves, e.g. CO2 from air, methanol from CO2, or with impregnated activated carbon, e.g. H2S from CO2 or Hg from process gases. |
