Abstract

H2 production processes from steam methane reforming and combined cycle power plants require carbon dioxide removal from raw synthesis gas to obtain a useful H2-rich product stream. In this work, a wide variety of operating configurations were techno-economically evaluated in Aspen Plus commercial process simulator to improve the efficiency and costs of the pre-combustion CO2 capture process based on chemical absorption using [P2228][CNPyr] ionic liquid. Multiple absorption (from 30 °C to 70 °C) and regeneration (between 90 °C and 120 °C) temperatures were tested along with four different regenerating pressures: 0.1, 0.25, 0.5 and 1 bar. Energy and solvent consumptions and capital and operating costs were calculated for nine configurations using the COSMO-based/Aspen methodology combined with Aspen Economic Analyzer tool. The most promising results were obtained when regenerating the IL at 1 bar and at elevated absorption and regeneration temperatures, due to the higher operating and equipment costs associated with vacuum and the greater utilities cost related to heat transfer when the gap between both temperatures grows. The minimum cost achieved was 64.1$/tCO2 considering an IL scaled up price of 50 $/kg, but it could even be further less than 40 $/tCO2 goal for new generation solvents, when only direct costs were considered.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal SEPARATION AND PURIFICATION TECHNOLOGY due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2022, it was in position 12/142, thus managing to position itself as a Q1 (Primer Cuartil), in the category Engineering, Chemical. Notably, the journal is positioned above the 90th percentile.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 3.91. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 4.73 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 7.57 (source consulted: Dimensions May 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-05-08, the following number of citations:

  • WoS: 25
  • Scopus: 44
  • OpenCitations: 36
Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-05-08:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 76.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 73 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 7.

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:
