Steam System
Intimately integrated into the SMR process is a steam system which provides
process steam as well as removes the large amount of waste heat required to cool
the furnace process outlet, shift outlet, and flue. The steam system allows a
hydrogen plant to be nearly self-sufficient. Many hydrogen plants generate surplus,
high-pressure steam that is exported to the refinery. They can be major steam
