Patent ID: 7707837

Claim:
A steam reforming system comprising: a pre-reformer for producing a pre-reformed gas made primarily of methane from feedstocks having been desulfurized; and a reformer for converting the pre-reformed gas to synthetic gases made primarily of hydrogen and carbon monoxide, wherein said steam reforming system further comprises: a gas turbine; and a heat recovery exchanger for heating the feedstocks and the pre-reformed gas and generating a steam used for pre-reforming the feedstocks by utilizing waste heat of said gas turbine, said heat recovery exchanger comprising a first heat exchanger for heating the feedstocks introduced to said pre-reformer by utilizing the waste heat of said gas turbine, a second heat exchanger for heating the pre-reformed gas supplied from said pre-reformer to said reformer, by utilizing the waste heat of said gas turbine, and a third heat exchanger for generating the steam used for pre-reforming the feedstocks in said pre-reformer also by utilizing the waste heat of said gas turbine.
