      abstract     = {Post-combustion carbon capture technology is seen as an
                      indispensable option for global CO2mitigation. Nevertheless,
                      the benchmark post-combustion carbon capture technology,
                      i.e. theMEA-based chemical absorption technology, has been
                      reported to be rather energy-intensive.Meanwhile, the
                      performance of the gas permeation membrane technology, one
                      of the emergingalternative carbon capture technologies, has
                      also been found to be restricted by the membraneproperties,
                      especially when it is designed to be applied in
                      industrial-scale plants. As a result, theapplications of the
                      post-combustion carbon capture technology in the power and
                      industrialsectors are faced with great resistance. On the
                      other hand, the research of post-combustioncarbon capture
                      for industry is found to lag behind the power sector. The
                      objective of this work isto advance the feasibility of
                      post-combustion carbon capture technology as well as
                      contribute tothe study of carbon capture in the steelmaking
                      industry.In order to do this, two types of hybrid
                      membrane/MEA carbon capture systems (Hybrid D1 $\&D2)$ were
                      designed in Aspen Plus®. In the Hybrid D1 system, a
                      single-stage membrane iscombined with an MEA system while a
                      cascaded membrane system and an MEA system arecombined in
                      the Hybrid D2 system. For comparison, two widely studied
                      standalone capturesystems (cascaded membrane $\&$ MEA) were
                      also modeled. The Polyactive® membrane wasselected to be
                      the investigated membrane material. These carbon capture
                      systems weredeployed in a reference coal-fired power plant
                      and a reference iron $\&$ steel plant, respectively. Amodel
                      of the power plant was simulated using EBSILON®
                      Professional to represent the detailedoperation. Pinch
                      analysis was used to analyze the potential for waste heat
                      integration of thecapture systems into the water-steam
                      cycle. In addition, the performances of the capturesystems
                      when the power plant is operated at part-load were
                      investigated. As for the iron $\&$ steelplant, the energy
                      use network and point sources of CO2 emissions inside the
                      plant wereanalyzed so as to specify the boundary condition
                      for carbon capture. A cost model based on thediscounted cash
                      flow approach was developed for economic analysis.In the
                      power plant, it is revealed that the Hybrid D1 system is
                      neither an energy-efficient nor acost-effective design. The
                      Hybrid D2 system, however, has shown to lead to both a
                      lowerefficiency penalty (9.7 $\%-pts)$ and a lower CO2
                      avoidance cost (48.8 €/tCO2) than the standalonecascaded
                      membrane and MEA systems in the power plant. A basic
                      principle for the design of ahybrid system is concluded
                      according to the result.In the iron $\&$ steel plant, the
                      Hybrid D2 system leads to the lowest CO2 avoidance cost
                      (53.9€/tCO2) but the differences in the avoidance costs of
                      different capture systems are insignificantconsidering the
                      uncertainty of the cost model. It is also found that the
                      steam supply strategy haspronounced impacts on the cost
                      competitiveness of a carbon capture system. In addition, it
                      isdisclosed that an overall lower CO2 avoidance cost can be
                      achieved by deploying multiple typesof capture systems to
                      deal with different point sources of CO2 emissions as
                      compared todeploying only one single type of capture
                      system.},
