    Abstract: Process for the production of synthesis gas by catalytic steam reforming of a hydrocarbon containing feedstock in parallel in an autothermal steam reformer and heat exchange reformer, the heat for the steam reforming reactions in the heat exchange reformer being provided by indirect heat exchange with the combined effluent of the heat exchange reformer and a portion of the autothermal steam reformer.

    Abstract: The present disclosure relates to a process plant and a process for production of a hydrogen rich gas, comprising the steps of (a) directing an amount of a synthesis gas comprising at least 15%, 50% or 80% on dry basis of CO and H2 in combination, a gas comprising steam, and a recycled intermediate product gas to be combined into a first reactor feed gas, (b) directing said first reactor feed gas to contact a first material catalytically active in water gas shift reaction, producing an intermediate product gas, (c) splitting said intermediate product gas in the recycled intermediate product gas and a remaining intermediate product gas, (d) combining said remaining intermediate product gas with a further amount of synthesis gas forming a second reactor feed gas, (e) directing said second reactor feed gas to contact a second material catalytically active in the water gas shift reaction, producing a product gas, characterized in the H2O:CO ratio in said first reactor feed gas being from 0.5 to 2.0 and the H2O:CO ratio in said second reactor feed gas being from 0.5 to 2.0. with the associated benefit of distributing the heat development and thus reducing the maximum temperature in the reactors by limiting the extent of reaction of the reacting mixture, and thereby reducing the amount of steam required for limiting methanation.
