    摘要： A process and a related equipment for producing ammonia synthesis gas from a hydrocarbon-containing feedstock (20), the process comprising the steps of: primary reforming with steam (21), secondary reforming with an oxidant stream (23), and purification of the effluent of said secondary reforming, said purification comprising a step of shift conversion (13) of carbon monoxide, wherein the synthesis gas (25) produced by said secondary reforming is subject to a medium-temperature shift over a copper-based catalyst, and the global steam to carbon ratio of the process is not greater than 2.

    摘要： A methanation section for producing substitute natural gas (SNG) by reacting a fresh syngas, the methanation section comprising adiabatic reactors connected in series, with heat removal and reacted gas-recirculation, wherein the fresh syngas is fed in parallel to said adiabatic reactors. In a preferred embodiment the reacted gas is recirculated to the first reactor and further dilution of the fresh gas at the inlet of the first and second reactor is achieved by steam addition.
