Pure hydrogen production from natural gas via fuel processor based on steam reforming with WGS and PSA units

By G. Ercolino, M. A. Ashraf and S. Specchia


H2 is produced mostly from reforming of fossil fuel followed by a series of purification steps. This work is a sensitivity analysis of H2 production plant from natural gas. The plant consists of steam reforming, a water gas shift, and a pressure swing adsorption units to produce high-purity H2. The sensitivity analysis was carried our varying the percentage of H2 recovery from the PSA (70-75%) and the operating pressure (5-30 bar,g), in order to identify the best operative conditions that provide the best equilibrium between H2 production and the overall efficiency of the system

Topics: water gas shift, pressure swing adsorption, sensitivity analys
