“…In general, the excellent regenerability of PEI-magnetic nanocomposites can be explained by the low volatile nature of PEI, good thermal stability, and excellent interaction between PEI and magnetic nanocomposites, [129,130]. Yuan et al [131] defined capture rate as the fraction of the CO 2 amount captured from the feed stream. In practice, the capture rate can be zero, which corresponds to the membrane unit bypass scenario.…”

“…International Journal of Chemical Engineering Yuan et al [131] highlight two key properties of the membrane that have a direct effect on the energy and mass balance during the separation process, and they are CO 2 permeability and CO 2 /N 2 selectivity. e permeability is determined by the gas permeability of the membrane and defined as the average permeability over the thickness of the membrane.…”

The adoption of nanodoped membranes in the areas of gas stream separation, water, and wastewater treatments due to the physical and operational advantages of such membranes has significantly increased. The literature has shown that the surface structure and physicochemical properties of nanodoped membranes contribute significantly to the interaction and rejection characteristics when compared to bare membranes. This study reviews the recent developments on nanodoped membranes, and their hybrids for carbon capture and gas separation operations. Features such as the nanoparticles/materials and hybrids used for membrane doping and the effect of physicochemical properties and water vapour in nanodoped membrane performance for carbon capture are discussed. The highlights of this review show that nanodoped membrane is a facile modification technique which improves the membrane performance in most cases and holds a great potential for carbon capture. Membrane module design and material, thickness, structure, and configuration were identified as key factors that contribute directly, to nanodoped membrane performance. This study also affirms that the three core parameters satisfied before turning a microporous material into a membrane are as follows: high permeability and selectivity, ease of fabrication, and robust structure. From the findings, it is also observed that the application of smart models and knowledge-based systems have not been extensively studied in nanoparticle-/material-doped membranes. More studies are encouraged because technical improvements are needed in order to achieve high performance of carbon capture using nanodoped membranes, as well as improving their durability, permeability, and selectivity of the membrane.

“…The quantification of operational flexibility is often achieved throughout the literature by solving either the mathematical optimization problem that was defined by Grossmann et al in 1985 or by solving a modified version of the formulations based on the concept of Grossmann et al An overview of recent developments can be found in Grossmann et al [56] Operational flexibility is therefore directly connected, but not limited, to the solution of an optimization problem under uncertainty. [55] Yuan et al [84] present a membrane based flexible carbon capture system. Using optimization methods, the aim of the study is to identify a system design with minimized costs operable under intended time variable operation of the upstream natural gas power plant according to electricity prices.…”

Increasing economic and environmental challenges leads to the need for changes in the chemical industry. In this context, a promising approach is utilizing flexible apparatuses and flexible plants to react to changing boundary conditions. However, the concept of flexibility in chemical engineering, which originated in manufacturing, still lacks a comprehensive organization and categorization of different types of flexibility. Thus, in this work, the origin of flexibility in manufacturing is traced, and a literature overview on flexibility in chemical engineering is provided. Based on a subsequent cluster analysis, four types of flexibility are identified and defined. Furthermore, this work enables research on flexibility to be integrated into a general and consistent definition of flexibility. The definitions are applied to examples from literature to achieve comparability. While enabling the qualitative assessment of flexibility, this work identifies open research gaps regarding the quantification of flexibility.

“…21,22 There is also increased demand for flexible power generation systems that can adapt to varying operation conditions and market conditions on the order of minutes. 23 The EMAR system can ramp up and down the flue gas capture by increasing and decreasing the electricity supplied to the electrochemical desorption train. In comparison, the response time of the thermal amine process will likely be constrained to a dynamic CO 2 capture rate and material safety constraint during heating ramps.…”

The electrochemically mediated amine regeneration (EMAR) process presents an alternative route to the conventional thermal amine regeneration for carbon capture from a flue gas source. In this study, we conducted an economic analysis on the EMAR system for postcombustion CO2 capture from a 550 MWe power plant capturing 3.1 MtCO2 annually and from a mini steel mill with annual capture close to 170 ktCO2 . We followed the recommendation of the National Energy Technology Laboratory (NETL) 2010 report to estimate the cost of CO2 avoided ([$/tCO2 ]). Detailed cost modeling of the electrochemical separation stage was conducted. This is integrated with the entire process flowsheet (e.g., including absorber, compressor, pumps, and other auxiliary equipment). We identified the membrane cost as the dominant capital cost for the electrochemical separation train. At a membrane unit price of less than $10/m2, the CO2 capture cost can be reduced to below $50/tCO2 with optimized process conditions (e.g., desorption pressure and utilization of waste heat). Improvements in process design, cell construction, and solvent formulation may lead to additional reductions in the CO2 capture cost.
