1. A method for revamping a plant for the production of a hydrogen-containing synthesis gas, said plant comprising a conversion section, at least one fired device producing heat for said conversion section and a fuel line being directed to said fired device;
said plant being fed with a natural gas feedstock and said natural gas feedstock being split into a first fraction used as process gas in the conversion section and a second fraction used as fuel and directed to said fired-device;
wherein:
a gasification section including a gasifier fed with a carbonaceous feedstock is added to said plant, wherein said carbonaceous feedstock is solid or liquid;
said gasification section being arranged to produce at least part of said fuel directed to said fired device, replacing a corresponding part of said second fraction of natural gas,
wherein the conversion section includes a reforming section, and the effluent of said gasifier is used as fuel, not as a process gas, and provides at least part of the total amount of fuel directed to said reforming section.
