Carbon Oxides are poisonous for many Hydrogenation reactors. CO/CO2 removal units are usually followed by Methanation units to reduce Carbon Oxides to trace levels. The Methanation reactions are reverse of Steam Reforming reactions and are strongly exothermic. Following reactions take place in Methanation Reactor to reduce CO/CO2 on Nickel catalyst. CO + 3H_2 → CH_4 + H_2 O CO_2 + 4H_2 → CH_4 + 〖2H〗_2 O After passing through the Heat Exchangers and reaching the reaction temperature, the hydrogen gas will enter the Methanation reactor and the Methanation Reactions will take place. The design and fabrication of this unit has been completely done by Chaman Company. The use of high-efficiency and long-life catalyst along with the unique design of this unit, which can guarantee safety at high temperatures, are the advantages of this design.
