Methanation with regard to the symbiosis of the Borealis and voestalpine industries operating in the chemical park in Linz (Austria) is studied using the commercial software Aspen Plus. The methanation of carbon dioxide with hydrogen allows a reduction of carbon dioxide emissions, especially by considering green energy for electrolysis. The reaction dynamics of carbon dioxide methanation is studied to obtain a suitable range of operating parameters, and a general flow diagram is proposed. Flow schemes and process parameters are proposed based on thermodynamic equilibrium and kinetic reaction models. The effects of using coke oven gas in an ammonia synthesis-methanation complex are presented.
