“…Since the SEWGS unit co-captures H 2 S (van Dijk et al, 2011), the preshift section can be designed as sour or clean shift. Because of the increased operating temperature, steam can be used in the cycle to drive both the CO 2 recovery and purity to >95% (Boon et al, 2015), values higher than obtainable for conventional low-temperature PSA separations (Casas et al, 2013). The development of the SEWGS process aims at minimizing the steam requirement for the CO 2 separation in the PSA cycle.…”

“…The development of the SEWGS process aims at minimizing the steam requirement for the CO 2 separation in the PSA cycle. Depending on the feed composition, the total steam usage in SEWGS is between 0.2 and 2 mol steam per mol CO 2 captured (Boon et al, 2015). Moreover, a significant amount of the steam present in the syngas goes with the high pressure H 2 -rich stream and is used in the combined cycle.…”

This paper, which is part of a special issue of the International Journal of Greenhouse Gas Control, gives an overview of the latest achievements in the pre-combustion decarbonisation route for the production of electricity with CO2 capture. Pre-combustion technologies applied to two different fuels are considered, natural gas and coal, since they cover most of electricity production from fossil fuels worldwide. The work first discusses in detail the different sections in which a power plant with pre-combustion CO2 capture can be divided. For each section, the available technologies with corresponding advantages and disadvantages are presented. Next, the plant lay-outs for natural gas and coal proposed in literature, including heat & mass balances and the economic assessment, are discussed. In general, research activity in pre-combustion decarbonisation for power production focused more on coal than on natural gas-based plant since in the latter case the plant complexity and costs are not competitive with post-combustion CO2 capture, which is a technology on the verge of commercialization. Finally the paper briefly discusses pre-combustion CO2 capture in industry especially those projects where CO2 is captured and stored or used for EOR

“…To inhibit coke deposition on the catalyst and achieve a purified H 2 output, the process operation is adjusted to 3.5 MPa pressure, steam-to-carbon ratios of 3.5, and high temperatures [42]. After the reformer, the mixture of gases goes through a heat recovery, and water gas shift reactor where an additional H 2 is produced from the reaction between the steam and carbon monoxide then, the mixture of gases goes through either a pressure swing adsorption or through a CO 2removal and methanation producing virtually pure H 2 [43]. Membrane reactors offer a remarkable solution.…”

Recognizing and procurement of a sustainable energy system are among the supreme important problems that today's scientists should tackle. Interchanging the existing fossil fuels and transforming them into a sustainable fuel is one of the vital pieces in that system. Hydrogen as an energy carrier, obtained from light hydrocarbons, can take an essential role in the matters of sustainability, eco-friendly emissions, and energy saving. Our enthusiasm in stirring toward a hydrogen economy has its root in the vision of securing energy requirements at a satisfactory price, with larger competence and small environmental destruction associated with the utilization of traditional fuels. Hydrogen production pathways and relevant issues are discussed here. This chapter highlights the recent technological progress in the light hydrocarbons toward sustainable hydrogen production.

“…The purge step significantly influences the carbon capture rate (CCR), as more steam desorbs more CO 2 product. Then, the pressure in the column is increased step by step during three pressure equalization steps, and finally, a repressurization step is done by using part of the H 2 product [23,24]. A schematic representation of an integrated steel mill with SEWGS technology is presented in Figure 2.…”

Life Cycle Assessment of SEWGS Technology Applied to Integrated Steel Plants

The environmental evaluation of the sorption-enhanced water–gas shift (SEWGS) process to be used for the decarbonization of an integrated steel mill through life cycle assessment (LCA) is the subject of the present paper. This work is carried out within the STEPWISE H2020 project (grant agreement No. 640769). LCA calculations were based on material and energy balances derived from experimental activities, modeling activities, and literature data. Wide system boundaries containing various upstream and downstream processes as well as the main integrated steel mill are drawn for the system under study. The environmental indicators of the SEWGS process are compared to another carbon capture and storage (CCS) technology applied to the iron and steel industry (e.g., gas–liquid absorption using MEA). The reduction of greenhouse gas emissions for SEWGS technology is about 40%. For the other impact indicators, there is an increase in the SEWGS technology (in the range of 7.23% to 72.77%), which is mainly due to the sorbent production and transportation processes. Nevertheless, when compared with the post-combustion capture technology, based on gas–liquid absorption, from an environmental point of view, SEWGS performs significantly better, having impact factor values closer to the no-capture integrated steel mill.
