Process and process unit for the preparation of ammonia synthesis gas from a hydrocarbon feedstock comprising sequentially primary and secondary catalytic steam reforming of the feedstock in a primary heat exchange steam reformer and in a subsequent secondary reformer, wherein an effluent stream of primary steam reformed gas is heated by indirect heat exchange with a hot product effluent of secondary reformed gas prior to introduction of the primary steam reformed gas into the secondary reformer.

Process and process unit for the preparation of ammonia synthesis gas

A process for the preparation of ammonia synthesis gas includes supplying a feedstock gas, optionally mixed with a flue gas, to at least one pair of reforming reactors. Each reactor has a process and fuel side and a combustion side. Each pair of reactors is arranged in parallel on the process and fuel side, and in series on the combustion side. A flame temperature in each pair of reactors is controlled by supplying an excess of combustion air to a first reactor of the pair, and oxygen-depleted combustion air to a second reactor of the pair.
