“…Moreover, the narrower thickness of hollow fibers facilitates the quicker removal of heat generated during CO 2 adsorption on the adsorbent particles, favoring an isothermal environment. Additionally, a decrease in adsorbent thickness leads to enhanced productivity due to a reduction in the cycle time period, which is consistent with the results of Hosseini et al 5 4.6.

“…The differential elements on the fiber side are generated by making differential changes Δ z and Δ r along the unit vectors z and r , while the differential element on the gas and water sides is generated only by making the differential change Δ z . The principal assumptions and equations to develop the model are summarized as follows. , For a more detailed insight into the mathematical modeling, one can refer to the work by Hosseini et al The lumen layer has a negligible thermal capacity. Ideal gas and mixture are assumed. Axial diffusion in the gas phase is neglected compared to bulk movement. N 2 adsorption has been neglected according to the assumption presented by Rezaei et al The contribution of the polymer fiber to CO 2 adsorption is negligible in comparison to sorbent particles. There is a thermal equilibrium between the polymer fiber and the sorbent particles. Intraparticle mass transfer resistance is negligible …”

“…Several technologies, including adsorption, absorption, gas hydrate, and membrane-based processes, have been proposed for the separation of CO 2 from flue gas . The key factor in response to such a challenge is to develop a process producing high purity and recovery but consuming less energy compared to commercial technologies such as amine absorption . Adsorption is one of the promising carbon capture technologies that can operate at high purity and reasonable energy consumption levels.…”

Recently, CO 2 capture has been given attention as an effective way to mitigate the impacts of global warming. However, CO 2 capture through adsorption technology is restricted by the cost of energy consumption, and the optimization of this technology deserves to be noted. Rigorous mathematical models along with optimization algorithms result in significant savings in both time and cost of the experiment. In this paper, a purposeful optimization for the rapid temperature swing adsorption (RTSA) cycle using amino silica hollow fiber adsorbents was presented to evaluate the competitiveness of this fledgling technology with other adsorption methods. Achieving the highest purity and recovery as two conflicting objectives and obtaining the highest process productivity at the lowest energy consumption were two demands for the applicants, which were optimized through a hybrid model of the multiobjective differential evolution (MODE) algorithm and Technique for the Order of Preference by Similarity to Ideal Solution (TOPSIS) decision-making method. The key operating parameters containing water velocity (0.1−2 m/ s), feed and purge gas velocity (0.1−6 m/s), and cooling (15−40 °C) and heating (80−120 °C) temperatures, as well as adsorption (50−500 s), heating (100−250 s), and sweeping (20−150 s) step times, were chosen as decision variables to find the optimal operating point from the Pareto set. A summary of performance comparison between the amino silica hollow fiber-based RTSA cycle and other CO 2 capture technologies available in the literature showed that this cycle with purity and recovery above 80% operates below current international standards. In addition, the energy consumption in this system was higher than other technologies due to the high heat of adsorption of the amino silica adsorbent, which can be overcome to this challenge by choosing a suitable adsorbent or configuration.

Conventional temperature swing adsorption (TSA) is mainly applied for the removal of trace contaminants. Indirectly heated and cooled adsorbers were developed to make bulk separation economically feasible. A quasi-continuous TSA process to remove CO 2 from an N 2 /CO 2 mixture with a pilot plant is established. The experimentally determined data are taken to validate and to adjust a 2D simulation model. For the validation, the CO 2 desorption, the N 2 recovery rate as well as the axial temperature profile are compared. The successful model validation can be seen in the good agreement between simulation and experimental results. Moreover, this process is able to separate high amounts of CO 2 and to produce a nearly CO 2 -free product stream.

Climate issues, especially linked to the greenhouse effect and global warming, are receiving increasing attention. The most direct cause is the overproduction of anthropogenic carbon dioxide. Carbon capture and storage (CCS) is one of the main strategies for mitigating and controlling CO 2 emissions from large emission sources, as well as achieving large-scale CO 2 emission reductions. [1] In October 2018, the Intergovernmental Panel on Climate Change (IPCC) released the 1.5 C Special Report in Incheon, which found that global CO 2 emissions would need to fall by %45% from 2010 levels by 2030, and that the world should aim to be carbon neutral by %2050 by removing CO 2 from the air to stabilize remaining emissions. [2] In June 2019, China released The Third Information Bulletin and The Second Biennial Update, which highlighted CO 2 as the main greenhouse gas emitted by China. However, compared with 2005, China's energy-related CO 2 emissions per unit of GDP decreased by 40.7% in 2016. Nevertheless, the rapid and widespread reduction in carbon emissions is required from all sectors to limit the global temperature rise to 1.5 C or even 2 C. [3] The desire for a shared future for mankind has prompted China to establish increasingly severe emission-control scenarios that call for accelerated development of practical carbon capture technology. [4] However, a lack of generalized methods and reasonable benchmarking analysis of the energy efficiency of typical carbon capture technologies may lead to low reliability, poor generalization, and even contrasting research conclusions regarding their energy efficiency and energy consumption. Thus, an adequate benchmarking analysis framework is urgently required for carbon capture technology. CCS is widely regarded as a new solution to the common challenges currently faced by human society. [5] However, in recent years, CCS research has been inhibited by the "old" problem of excess specific-heat consumption. Thus, it is difficult to promote technological development with sustainable cost control. Moreover, according to the first law of thermodynamics, current carbon capture technology typically requires heat consumption of 3-4 GJ to capture 1 ton of CO 2. [6] Furthermore, its theoretical exergy efficiency is generally below 20% and it exhibits low technology maturity, despite substantial potential for energy conservation and consumption reduction. [7] For post-combustion CO 2 capture, the feasibility of several technologies (such as absorption, adsorption, membrane, and cryogenic methods) has previously been demonstrated. [8] Adsorption is considered to be a
