A method for modernizing an ammonia synthesis loop (1) with a first converter (10) and a second converter (11) in series, the first converter (10) comprises a cartridge with one or more catalyst beds, the second converter (11) comprises a catalyst bed in direct contact with said vessel, the method comprising the steps of removing the second converter, and boosting the first converter by replacing the cartridge with a high-efficiency cartridge comprising a plurality of adiabatic catalyst beds and inter-bed heat exchangers, or an isothermal catalyst bed, and by reducing the concentration of inerts in said first converter. |
