Exergy Analysis of Methane Steam Reformer Utilizing Steelmaking Waste Heat

Abstract: System analysis was conducted on a proposed combined system for methane steam reforming comprising conventional hydrogen production and waste heat recovery from steelmaking. Operating data for a conventional methane steam reforming system were collected and analyzed. The results showed that the conventional system utilized only 60 % of the natural gas as raw material and the rest is consumed for supplying the reaction heat for methane steam reforming. On the basis of this data, the proposed system was evaluate… Show more

“…So far, the preparation of PCMs using spherical 14,15) and mesh-shaped 16) copper and system analysis [9][10][11][12][13] have been conducted for a high temperature system rather at over 1 000°C. These analyses concluded that natural gas consumption, enthalpy flow, CO 2 emission, cost, and exergy loss of hydrogen production were only 59.6 %, 59.7 %, 62.8%, 86.5%, and 65.8% of those of the conventional system, respectively.…”
