A method for generating hydrogen in a production facility having a
catalytic steam reformer, a boiler downstream of the catalytic steam
reformer, optionally having a prereformer, and optionally having a shift
reactor, wherein the reformer feed gas mixture is formed using a
steam-containing recycle gas mixture which was formed from boiler
effluent. The boiler generates steam which may be used to form the
reformer feed gas mixture, used elsewhere in the production facility,
and/or used for export steam.
