“…The regenerated lean solution is returned to the absorber, and compressed CO2 is collected in the upper part of the desorber column and transported. 12 Currently, direct gas-liquid contact using amine-based solutions is the leading postcombustion process carbon capture technology, with a market presence higher than 90% due to a high reaction rate, good absorption performance and low cost of production.…”

Post-combustion carbon capture (PCC) using membrane technology is a rising alternative to PCC processes, which is based on conventional equipment, such as CO2 absorptiondesorption in packed columns, to mitigate human-associated climate change. Research on CO2 capture system has been centered on improving the CO2 absorption process efficiency, while little attention has been devoted to the performance of the solvent regeneration technology.In this review, research development is focused on the performance of the CO2 desorption process using hollow fiber membrane contactors (HFMCs). The main impact factors in membrane contactor technology are presented, including solvent and membrane material selection, membrane module design, mass transfer correlations, operational issues, modeling and simulations. Each section has been discussed in terms of its current status while describing future challenges to improve the technology for its industrial implementation.

The synergistic pressure and temperature swing adsorption (SPTSA) technology is designed for purifying coalbed methane (CBM) are proposed in this work. Cyclic processes including four steps: cooling, pressurization, heating, and depressurization. Ideal adsorption solution theory (IAST) was used to evaluate the separation effect. Super activated carbons (SACs) with specific surface area exceeds 3000 m2 g−1 were prepared and used as adsorbents. From 273 to 373 K, the adsorption selectivity (S) changes more than 4, while the S changes less than 2 with the pressure changes from 0.1 to 9 MPa, indicating that temperature change is more conducive to improve the CH4 purity compared to the pressure change. However, more CH4 purification capacity can be obtained by pressure change. In cyclic SPTSA process, the CH4 purification capacity is generally increased by more than 30% compared with the pressure swing adsorption technology, which indicated that CH4 separation and purification under the synergistic action of temperature and pressure is theoretically feasible and has a broad prospect in the CBM purification. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…As one of the highest concentrations of greenhouse gases in the atmosphere, carbon dioxide (CO 2 ) has caused global climate change, which has become one of the major environmental problems that humanity faces at present. This trend is foreseeable and will not change in the future; thus, carbon capture, utilization and storage (CCUS) [1] technology must be implemented to transport and utilize the captured CO 2 and store it in deep-sea geological wells in a supercritical state. The post-combustion capture technology based on the chemical absorption of monoethanolamine (MEA) solvent is the most effective option to solve the problem of CO 2 emissions from fossil fuel power plants [2].…”

For the post-combustion CO2 capture (PCC) system, the time variability of the economic performance is key to the production process of such an actual industrial process. However, the performance index used by the conventional model predictive control (MPC) does not reflect the economy of the production process, so the economic cost function is used instead of the traditional performance index to measure the economy of the production process. In this paper, a complete dynamic model of the PCC system is constructed in Aspen Plus Dynamics. The effectiveness of the model is verified by dynamic testing; subspace identification is carried out using experimental data, a state-space equation between flue gas flow and lean solvent flow; the CO2 capture rate is obtained; and dynamic models and control algorithm models of accused objects are established in Matlab/Simulink. Under the background of the environmental protection policy, an economic model predictive control (EMPC) strategy is proposed to manipulate the PCC system through seeking the optimal function of the economic performance, and the system is guaranteed to operate under the economic optimal and excellent quality of the MPC control strategy. The simulation results verify the effectiveness of the proposed method.
