Abstract

See full text

The present invention relates to a revamp method for increasing the front-end capacity of a plant comprising

    a reforming section, wherein a feed is reformed in at least one reforming step to a reformed stream comprising CH4, CO, CO2, H2 and H2Oa shift section wherein the reformed stream is shifted in a shift reaction in at least a high temperature shift step,said method comprising the steps ofIn the High temperature shift step exchanging an original Fe-based catalyst with a non-Fe-based catalystIncreasing the feed flow to the reforming section, andThe HTS step is carried out at a reduced steam/dry-gas ratio (S/DG) compared to an original S/DG in the original HTS step with the original Fe-based catalyst.
