Abstract Light hydrocarbon feedstock is fed directly into the secondary reformer with excess of air over that to produce a stoichiometric mixture, the heat load of the existing primary reformer is maintained close to the original figure for increases in plant throughput of over 50%. After operating the heat recovery and shift system in a conventional manner the extra gas is treated in a PSA unit to remove any unwanted impurities and sufficient nitrogen so that the gas produced by mixing the main flow of gas and that from the PSA unit is suitable for ammonia synthesis in the existing equipment or a modification of it.
