Membrane reforming in converting natural gas to hydrogen: Production costs, Part II

The influence of the nanostructure on the effect of CO2 on the properties of Pd–Ag thin-film for H2 separation

“…However, the process is heat-transfer limited which decreases energy efficiency and causes an exergy loss. An efficient hybrid system (power + hydrogen) with a reduction in energy consumption of about 15% can be realized by using a H 2 membrane separation module downstream of a reforming reactor operating at about 650 • C [1][2][3][4]. Advantages in the process efficiency and economics, as well as a reduction of greenhouse gas emissions per kilogram of H 2 produced are thus possible.…”

Economics of hydrogen production

“…The TECHPOL programme estimated costs in 2004 (Krewitt & Schmid, 2004). Further data are extracted from studies in the literature (Acar & Dincer, 2014;Cormos, 2010Cormos, , 2014DEA, 2010;Gray & Tomlinson, 2002;Iaquaniello, Giacobbe, Morico, Cosenza, & Farace, 2008;Khamis & Malshe, 2010;Kreutz, Williams, Consonni, & Chiesa, 2005;NRC, 2004NRC, , 2008.…”

Natural Gas Catalytic Partial Oxidation: A Way to Syngas and Bulk Chemicals Production

“…This consortium grouped Italian universities and the engineering company Tecnimont KT, cooperating in the development of this innovative technology, that individuated as critical points membrane manufacture and assembling and catalyst optimization. The project resulted in the design and operation of a demonstrative plant (capacity of 20 Nm 3 /h oh hydrogen), placed in Chieti Scalo, based on the integration of a steam reforming reactor with Pd and Pd/Ag based membranes for hydrogen separation (Barba et al, 2008;Iaquaniello et al, 2008;De Falco et al, 2011a;De Falco et al, 2011b). This installation, the first of this type and size, made it possible to completely understand the potential of selective membrane application in industrial hightemperature chemical processes.…”
