Heat and power integration studies have been carried out for a conventional methane
reforming based hydrogen production plant with capacity of 20.98 kgH2/h. Heat and power
integration results in utility profit due to electricity production in excess of process needs.
Heat integration alone results in a 36% reduction in utility cost. Operation at the minimum
hot/cold or hot/cold/electric utility cost doesn’t require hot utility (methane (fuel)), with a
consequent reduction of carbon dioxide emissions of 6.5%.
