Abstract: A hydrogen plant including a fuel reforming plant configured to receive and process hydrocarbon feedstock and configured to discharge wet reformate including a hydrogen-containing gas stream, and a condenser configured to cool the wet reformate. The hydrogen plant also includes a water separator configured to receive the cooled wet reformate, remove water from the wet reformate, and discharge dry reformate. The hydrogen plant further includes a hydrogen purifier configured to receive the dry reformate, process the dry reformate, and discharge pure or substantially pure hydrogen. A supplemental cooling system is provided in the hydrogen plant to cool the wet reformate in addition to the condenser.
