Toward Sustainable Solvent-Based Postcombustion CO2 Capture

Phase-Change Solvents and Processes for Postcombustion CO2 Capture: A Detailed Review

“…These are issues which have been highlighted in a few cases (e.g., see Zhang 17 ) and potential solutions have been proposed, but more research is needed in this direction. To this end, Papadopoulos et al 1,90 proposed a framework for holistic sustainability assessment of CO 2 capture solvents, including phase-change solvents, while Papadokonstantakis et al 91 extended this framework to account for holistic sustainability of process flowsheet modifications in view of different solvents. Note here that other materials used in CO 2 capture such as membranes also exhibit environmental impacts when viewed from a life-cycle perspective.…”

Multi-criteria screening of chemicals considering thermodynamic and life cycle assessment metrics via data envelopment analysis: application to CO2capture

“…Recent research has attempted to integrate these dimensions, but through the definition of aggregated scores showing the limitations mentioned before. [44][45][46] There are several attributes that can be used for the selection of CO 2 capture solvent candidates. [44][45][46] In our calculations, we use a set of properties that can be broadly categorised into the following groups:…”

Integrating superstructure‐based design of molecules, processes, and flowsheets

“…To extend both, the design space of the molecules and of the flowsheets, decomposition methods have been developed, which link CAMD to superstructure‐based design of flowsheet configurations. In a first stage of such decomposition methods, the design space of the molecules and/or flowsheets is reduced, for example, using CAMD with heuristic constraints based on guidelines and experience or multi‐objective optimization with molecular cluster techniques . In a second stage, the resulting MINLP is solved or individual process optimizations are performed if the number of remaining feasible solutions is small.…”

[50][51][52] In a second stage, the resulting MINLP is solved or individual process optimizations are performed if the number of remaining feasible solutions is small. In the second stage, the considered process models can consist of a detailed superstructure including discrete process flowsheet decision variables to select the flowsheet configuration.…”
