“…One possible way to circumvent this extreme condition is to displace thermodynamic equilibrium by removing one of the products from the reaction media. This has been done using two different approaches: either removing H 2 in Pd membranes (Bottino et al, 2006;Chen et al, 2006;Mori et al, 2007) or removing CO 2 in high temperature sorbents (Abanades et al, 2004;Balasubramanian et al, 1999;Mayorga et al, 1997;Ochoa-Fernandez et al, 2006;Yong et al, 2000). The process where the CO 2 is removed from the reactions media is the so-called sorption enhanced reaction process (SERP).…”

“…In the Pd‐based membrane, 99.8% of the incoming methane is reformed and 99% of the produced CO is shifted . The thermal energy required for the reforming process is provided from the combustion gases the temperature of which is increased to about 960°C in the supplementary firing of the plant .…”

Life‐cycle performance of natural gas power plants with pre‐combustion CO₂ capture

CO2 capture and storage involves technologies that separate, capture, and store CO2 from large facilities, such as fossil fuel power plants. Although it is a promising measure to meet environmental standards on carbon pollution, proposed technologies in power plants are energy demanding and decrease the energy generated per unit of input fuel when compared to business‐as‐usual scenarios. In this paper, we evaluate the environmental performance of two similarly structured combined‐cycle power plants with pre‐combustion capture. The first power plant performs methane steam reforming in an autothermal reformer, while the second plant uses a reactor that includes a hydrogen‐separating membrane. The two plants are compared both to one another and to a business‐as‐usual scenario using six environmental impact potentials (abiotic depletion, global warming, ozone layer depletion, photochemical oxidant formation, acidification, and eutrophication). The goal is to pinpoint environmental weaknesses and strengths of the two capture technologies. We find that the two plants result in similar impacts, decreasing the contribution to global warming of conventional operation but, at the same time, increasing other impacts, such as ozone layer depletion and photochemical oxidant formation. Additionally, the two capture plants result in higher cumulative non‐renewable and total energy demands, as well as in lower life‐cycle energy balances and efficiencies. The most direct measure to decrease the environmental impacts of the examined techniques would be to increase their efficiency, by decreasing the requirements of the processes in natural and energy resources.© 2014 Society of Chemical Industry and John Wiley & Sons, Ltd

“…However, these studies did not discuss the important issues such as evaluation of membrane area and energy requirements that ultimately affect the fixed and operating costs of the plant specifically in an integrated framework with other processes. Recently, Bottino et al 74 proposed a model for nonadiabatic industrial SMR under equilibrium conditions to study the effect of operating parameters on these two important aspects. Their investigations revealed that temperature profile plays a significant role in process economy and development of thin and permeable membranes is a key issue for improving the performance of large industrial plants.…”

Process intensification aspects for steam methane reforming: An overview

Steam methane reforming (SMR) is the most widely used process in industry for the production of hydrogen, which is considered as the future generation energy carrier. Having been perceived as an important source of H2, there are abundant incentives for design and development of SMR processes mainly through the consideration of process intensification and multiscale modeling; two areas which are considered as the main focus of the future generation chemical engineering to meet the global energy challenges. This article presents a comprehensive overview of the process integration aspects for SMR, especially the potential for multiscale modeling in this area. The intensification for SMR is achieved by coupling with adsorption and membrane separation technologies, etc., and using the concept of multifunctional reactors and catalysts to overcome the mass transfer, heat transfer, and thermodynamic limitations. In this article, the focus of existing and future research on these emerging areas has been drawn. © 2009 American Institute of Chemical Engineers AIChE J, 2009
