Steam-Methane Reforming. Most hydrogen produced today in the United States is made via steam-methane reforming, a mature production process in which high-temperature steam (700Â°Câ1,000Â°C) is used to produce hydrogen from a methane source, such as natural gas.
3 Condensate at steam temperature andunder 100 psig pressure has a heatcontent of 308.8 Btu per pound. (SeeColumn 4 in Steam Table.) If this conden-sate is discharged to atmosphericpressure (0 psig), its heat content instantlydrops to 180 Btu per pound.
