A process for producing synthesis gas using at least a first and a second steam reforming reactor each comprising at least one reaction stage enabling the circulation of a reaction mixture and at least one heat supply stage enabling the circulation of a heat transfer fluid, the process comprising the following steps:
- a) mixing a hydrocarbon feedstock gas and steam thereby forming the reaction mixture,
- b) simultaneously supplying the reaction stages of the first and second steam reforming reactors with the reaction mixture obtained in step a),
- c) producing combustion flue gases within the steam reforming reactors, wherein the combustion flue gases are used as heat transfer fluid,
- d) cooling the combustion flue gases to a temperature below 1000° C.,
- e) introducing the combustion flue gases from step d) into the heat supply stage of the first steam reforming reactor,
- f) recovering the combustion flue gases at the outlet of the first steam reforming reactor and introducing them into the heat supply stage of the second steam reforming reactor, and
- g) recovering synthesis gas at the outlet of the first and second steam reforming reactors.
